Background technique

As the application requirements of system-on-chip SOC (System On Chip) become richer and more complex, multi-core MPSOC (Multi-processor System On Chip) on chip has become an inevitable trend of development, and with the increasing demand for system performance High, the interconnect architecture between processor cores must be able to provide services with low latency and high throughput while being well scalable. The traditional bus-based centralized interconnection architecture has been difficult to meet the performance requirements of today's systems, and the network on chip NOC (Network On Chip) based on message switching has gradually become the preferred interconnection architecture for communication between processor cores. With the continuous development of technology, a variety of NOC network topologies have been proposed in related technologies, mainly including general network topologies and customized network topologies.

Figure 1 is a general network topology proposed in the related art. In this structure, routing nodes are connected through local interconnection lines, each routing node is connected to a local IP core through a network interface, and data packets are Each routing node transmits data packets from the source IP core to the destination IP core, but in the process of data packet transmission, the next routing node for data packet transmission only depends on whether the next routing node is idle, which is easy to cause. The transmission line is blocked, and the overall utilization rate of the transmission line is not high.

Figure 2 is a system-level customized network topology proposed in the related art, which customizes certain routing rules according to specific system architecture and scene requirements. Incoming data packets can only be transmitted up and down, or given different rules according to the parity column, etc. Since the customization method will limit the flexibility of the bus application, it cannot be directly used between various projects, and once the topology structure is determined, the data flow direction is determined and cannot be dynamically adjusted, which limits the data to some extent. The selectivity of the stream affects the transmission efficiency.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

In one embodiment, referring to FIG. 3 , a chip is provided, and the chip includes: a routing monitoring module 10 and a central processing module 20 .

Wherein, the routing monitoring module 10 is used to obtain the data transmission request and dynamic information of each routing node R; the central processing module 20 is used to determine the routing path according to the data transmission request and the dynamic information, and configure the corresponding routing node R based on the routing path, to The data transmission takes place via the corresponding routing node R.

Specifically, as shown in FIG. 3 , the chip may include multiple routing nodes R, each routing node R is connected by a local interconnection line (solid line in the figure), and some routing nodes R are connected through a network interface unit NIU ( Network Interface Unit) is connected with one or more local components to form a mesh on-chip network bus, where the local components can be CPU (Central Processing Unit, central processing unit), DMA (Direct Memory Access, direct memory access), APB (Advanced Peripheral Bus, peripheral bus), AHB (Advanced High Performance Bus, advanced high-performance bus), etc. There are no specific restrictions here. When data transmission is performed between different local components, the local component at the source end can package the data to be transmitted to generate a data packet, and inject the data packet into the routing node R connected to it through the network interface component NIU, and then pass through the on-chip network bus. The other routing node R transmits, and finally reaches the local component of the destination.

In order to realize the orderly transmission of data packets between each routing node R, avoid network congestion, and at the same time improve network bandwidth utilization, flexibility and reusability of network structure, etc. Central location, etc.) set up a routing monitoring module 10 as a routing monitoring and control center, responsible for collecting and monitoring the information of each routing node R in the on-chip network bus, including data transmission requests and dynamic information, wherein, data transmission requests include but not limited to is the source end, destination end, data packet size, priority information and transmission delay tolerance time of the data packet to be transmitted; dynamic information includes the information of the data packet to be transmitted and the quality of service (QoS) information of the routing node, The information of the data packet to be transmitted includes but is not limited to the source end, destination end, data packet size, priority information, information of the previous routing node and the next routing node R of the data packet to be transmitted. After the routing monitoring module 10 obtains the data transmission request and dynamic information of each routing node R, it directly sends the data transmission request to the central processing module 20 located on the on-chip network bus, and collects the dynamic information of each routing node R. The time stamp is appended and the packet is sent to the central processing module 20 located on the on-chip network bus.

The central processing module 20 may be a local component with data processing capability, such as a CPU, etc., which is newly added to the on-chip network bus, or may be a local component with data processing capability, such as a CPU, on the original on-chip network bus, which is not specifically limited here. . After receiving the information of each routing node R, the central processing module 20 selects different transmission rules and algorithms from the global perspective of the current bus, makes optimized routing suggestions for the data packets of each routing node R, and distributes the optimized routing suggestions to each. The routing node R is used to achieve the purpose of centrally managing and controlling each routing node R in the on-chip network bus. Specifically, the central processing module 20 determines the routing path according to the data transmission request and dynamic information, distributes the routing path to the corresponding routing node R through the routing monitoring module 10, and configures the corresponding routing node R to pass the corresponding routing node R data transfer.

In this example, by acquiring the information of each routing node in the on-chip network bus, and planning the routing path from a global perspective of the system based on the information of each routing node, the management and control of routing can be improved from the local to the system level, which can effectively reduce the network congestion, improve bandwidth utilization, and increase flexibility and reuse of network topologies. At the same time, since the path planning is implemented by the central processing module located on the on-chip network bus, the hardware resource occupation of the routing monitoring module located in the on-chip network bus can be effectively reduced, and the impact of the routing monitoring module on the area and power consumption of the on-chip network bus can be reduced. Influence, and when the central processing module uses the local components with data processing capabilities such as CPU on the original on-chip network bus, no additional hardware cost will be introduced, and the central processing module can be based on its own load. More complex and flexible run, and once the hardware is designed, it is difficult to change and lacks flexibility.

In one embodiment, when determining the routing path according to the data transmission request and the dynamic information, the central processing module 20 is specifically configured to: obtain the source end and the destination end of the data packet to be transmitted according to the data transmission request; The dynamic information of the routing nodes between them determines a routing path that satisfies a preset condition, and generates a routing path according to the routing path that satisfies the preset condition.

Specifically, before data transmission, the local component at the source first packages the data to be transmitted into a data packet and injects it into the routing node R connected to it through the network interface component NIU, and then the routing node R receives the data packet to be transmitted. Then, the data transmission request is sent to the routing monitoring module 10 . After receiving the data transmission request, the routing monitoring module 10 sends the data transmission request and the real-time acquired dynamic information of each routing node R to the central processing module 20 . After receiving the data transmission request, the central processing module 20 obtains the source end and the destination end of the data packet to be transmitted from the data transmission request, and performs path planning according to the dynamic information of the routing node R between the source end and the destination end, so as to Obtain a routing path that satisfies the preset condition, and generate a routing path according to the routing path that satisfies the preset condition. The preset conditions include, but are not limited to, the shortest transmission time, the fewest routing nodes, and the best transmission signal.

For example, referring to Figure 4, assuming that the local component A is the source end and the local component C is the destination end, when transmitting data packets from the source end to the destination end, before the data packets are transmitted, the For example, the dynamic information of routing node Router1 to routing node Router6 is used for routing path planning. During planning, the shortest routing path between routing node Router1 and routing node Router3 can be obtained first (the direct path shown by R1 in the figure) , and determine whether the routing path is used, if not, use the path as the current shortest routing path; if it is used, obtain the shortest routing path other than this path (R2 or R3 in the figure), and Determine if the path is used, if not, use the path as the current shortest routing path. Then, the central processing module 20 generates a routing path according to the current shortest routing path, including the identification information of each routing node on the current shortest routing path, etc., and sends the routing path to the routing monitoring module 10, and the routing monitoring module 10 distributes it to the corresponding routing Node R, to transmit the data packet to be transmitted through the corresponding routing node R.

In this embodiment, routing path planning is performed from the global perspective of the system according to the dynamic information of the source end, the destination end and all routing nodes between the data packets to be transmitted, rather than the routing path planning from the routing perspective or the bus perspective. , which can effectively reduce network congestion and improve bandwidth utilization.

In one embodiment, the central processing module 20 is further configured to dynamically adjust the routing path according to the dynamic information during the data transmission process.

As an example, when the central processing module 20 dynamically adjusts the routing path according to the dynamic information, it is specifically configured to: determine, according to the dynamic information, the usage of the path between the routing node where the data packet to be transmitted is currently located to the next routing node; is used, the unused routing path between the routing node where the data packet to be transmitted is currently located to the next routing node is obtained according to the dynamic information; the routing path is adjusted according to the unused routing path.

That is to say, during the data transmission process, if it is determined according to the dynamic information that the path between the routing node where the data packet to be transmitted is currently located to the next routing node is used, then the routing node where the data packet to be transmitted is currently located is re-acquired according to the dynamic information. to an unused routing path between the next routing node, and data transmission is performed based on the unused routing path, so as to ensure that the data packets to be transmitted can be transmitted in time.

For example, referring to FIG. 4 , assuming that the routing node where the data packet to be transmitted is currently located is Router1, and the next routing node determined before the data packet is transmitted is Router3 and the routing path is R1, then during the data packet transmission process, if the path R1 is used, and the central processing module 20 will re-plan the route according to the dynamic information of the routing node. As an example, the central processing module 20 calculates a recommended path, such as R2, according to the QoS information of the data packets to be transmitted, combined with the current data packet transmission conditions on the routing nodes Router1, Router2 and Router6 and the priorities of these data packets as path planning conditions. Or R3, so that the data packets to be transmitted at the routing node Router1 do not need to wait on the path R1, and can immediately start to transmit on the path R2 or R3, which effectively improves the network utilization rate and transmission bandwidth. Of course, dynamic and flexible adjustment of the routing path may also be performed based on other dynamic information, which is not specifically limited here.

In this embodiment, in the process of data transmission, by dynamically and flexibly planning the routing path from the global perspective of the system and the current congestion degree of the network according to the dynamic information of the routing node, the network utilization rate and the transmission bandwidth can be effectively improved.

As another example, when the central processing module 20 dynamically adjusts the routing path according to the dynamic information, it is specifically configured to: determine according to the dynamic information that there are multiple data packets to be transmitted within one processing cycle of the routing node and need to be transmitted through the same routing path , obtain the priority of each data packet to be transmitted according to the dynamic information; clear the same routing path in advance according to the priority of each data packet to be transmitted.

Further, when the central processing module 20 clears the same routing path in advance according to the priority of each to-be-transmitted data packet, it is specifically configured to: prohibit in advance the transmission of the low-priority to-be-transmitted data packets through the same routing path.

For example, referring to FIG. 5 , in one processing cycle of the routing node, if there are multiple data packets to be transmitted that need to be transmitted through the same routing path, for example, the data packets to be transmitted from the routing node Router1 are transmitted to the routing node through the path R1. Router3, the data packets to be transmitted of the routing node Router2 are transmitted to the routing node Router3 via the path R2 and the path R1, and the data packets to be transmitted of the routing node Router6 are transmitted to the routing node Router3 via the path R3 and the path R1, and each to-be-transmitted data packet is obtained at this time. The priority of the data packets. Assuming that the priority of the data packets to be transmitted of the routing node Router1 is the highest, then the data packets to be transmitted of the routing node Router2 and the data packets to be transmitted of the routing node Router6 will be regulated to other routing paths in advance. The path R1 is locked to ensure that the data packets with the highest priority to be transmitted are transmitted to the routing node Router3 via the path R1.

In other words, if there are data packets to be transmitted with higher priority and higher real-time performance that need to be transmitted on the path R1, the central processing module 20 will clear the path R1 in advance, for example, the data packets to be transmitted with lower priority will be transmitted in advance Control to other routing paths (the data packets that are being transmitted will continue to be transmitted), clear and lock the path R1 in advance to ensure that the subsequent data packets with higher priority and higher real-time performance can be transmitted with low delay.

In this embodiment, dynamic transmission control is performed according to the priority of the data packets to be transmitted, so as to ensure that subsequent data packets with higher priority and higher real-time performance can be transmitted with low delay.

In one embodiment, the central processing module 20 is further configured to perform security management and control on the routing node corresponding to the routing path during the data transmission process.

Further, when the central processing module 20 performs security management and control on the routing node corresponding to the routing path, it is specifically used for: when the running time or running state of the chip satisfies the preset condition, controlling the routing node in the security management and control state to control the non-secure data. Package is prohibited. Wherein, the running status includes but is not limited to the safe startup running status and the unauthorized safe access status.

That is to say, during the data transmission process, the central processing module 20 also obtains the running time or running state of the entire chip, and then performs dynamic security management and control on each routing node based on the running time or running state. For example, in certain time periods or operating states, it is possible to flexibly restrict the access rights of some local components (such as master GPU, etc.) to other local components (such as slave SRAM, DDR, etc.), such as restricting blacklisting access from the master device to the slave device.

As an example, referring to FIG. 6 , when the local component E needs to access the local component C, within a period of initialization after the security startup phase, the routing node Router3 will start the security control mechanism through the authorization of the central processing module 20, such as The access restriction is implemented through the SWTICH (switch) in the routing node Router3, and the local component E in the blacklist is prohibited from accessing it from various paths until after initialization or after the signature of the local component E is verified, through the central processing module 20. Once authorized again, the routing node Router3 lifts the access restriction to the local component E in the blacklist, thereby restricting the access of the master device in the blacklist to the slave device and ensuring the security of data transmission.

As another example, referring to FIG. 6 , during system operation, if it is found that some local components (such as the main device GPU) access an alarm to some unauthorized security addresses, the local components (such as the main device GPU) are prohibited from accessing certain unauthorized security addresses. Access to certain local components within the bus (eg slave SRAM, etc.).

In this embodiment, by performing dynamic security management and control according to the running time or running state of the chip, the security of the entire on-chip network bus can be guaranteed. That is to say, the central processing module can perform more cross-condition operations, such as superimposing factors such as the security and power supply of the entire network into the dynamic control of routing nodes, so as to control the routing nodes from a system perspective rather than a routing perspective or a bus perspective. On-chip network bus for scheduling and security control.

To sum up, in the chip of the embodiment of the present invention, the information of each routing node in the on-chip network bus is obtained through the routing monitoring module, and the routing path is determined and dynamically adjusted based on the information of each routing node from the system global perspective through the central processing module, The management and control of routing is improved from local to system level, which can effectively reduce network congestion, improve bandwidth utilization, and improve the flexibility and reusability of network topology. At the same time, through the central processing module on the on-chip network bus for global traffic control, it is possible to use the computing power of the central processing module such as CPU without the cost of large hardware cost and complexity, through the combination of software and hardware, and according to more crossovers The condition performs dynamic traffic control, security control, and power consumption control on data packets from a system-wide perspective.
