Definitions
- the invention relates to a method of transmitting data between functions implemented on an electronic chip of the manycore type comprising a plurality of execution cores.
- the invention also relates to an electronic chip of the manycore type.
- a “multi-core” processor is a processor having at least two cores or computing units etched within the same chip (“chip” in English) and which work. in parallel.
- a heart is a set of circuits capable of executing programs independently.
- cluster is a set of cores which communicate with each other through shared memory.
- the clusters are interconnected by communication systems implementing different communication techniques (eg NoC, acronym for “Network-on-Chip” or parallel bus type AXI, (acronym for “Advanced extensible Interface”) .
- Such manycore processors have architectural properties, which in addition to allowing the execution of massively parallel computations, also make it possible to host different functions in terms of criticality and safety, functions which were previously hosted on CPUs and therefore different housings.
- the use of chips comprising a “manycore” processor makes it possible to reduce the weight, the bulk as well as the electrical consumption of an architecture implementing many functions.
- this solution goes hand in hand with a loss of reliability linked to common failure modes, which is problematic when it is necessary to be able to ensure a high level of safety for a software process, eg for the control of the various components. of an airplane.
- the loss of puce causes the loss of all the functions hosted on it. The probability of losing several functions simultaneously is therefore increased, which can be dramatic in the case of an airplane.
- a method of transmitting data between functions implemented on a first electronic chip of the manycore type is described.
- the first electronic chip comprises a plurality of execution cores, said execution cores being grouped together in a cluster, said clusters being interconnected by at least two communication systems.
- the data transmission method comprises the steps of: implementing a first function on a first cluster; implementing a second function on a second cluster, characterized in that said second function is also implemented on a third cluster different from said first and second clusters; and transmitting at least one piece of data between said first function and said second function.
- transmitting at least one piece of data between said first function and said second function comprises transmitting a piece of data between said first function and said second function both on a first communication link belonging to a first communication system and on a second communication link belonging to a second communication system different from said first communication system.
- said first communication system is of the network on a chip type.
- said second communication system is a parallel bus.
- said first electronic chip being interconnected to a second electronic chip of the manycore type distinct from said first electronic chip, said first function is also implemented on a first cluster of said second electronic chip and said second function is further implemented on a second cluster of said second electronic chip.
- said first function implemented on one of said first or second chips transmits at least one data item to said second function implemented on the other of said first or second chips at the same time on a first type communication link.
- said first electronic chip being interconnected to a third electronic chip of the multi-core type, said first function is further implemented on a first core of said third electronic chip and said second function is further implemented on a second core of said third electronic chip.
- said first function transmits at least one data item to said second function both on a first communication link of Ethernet type and on a second communication link of PCIe type.
- a manycore type electronic chip comprising a plurality of execution cores is also described.
- the execution cores are grouped into clusters, said clusters being interconnected by at least two communication systems.
- the manycore type electronic chip includes:
- a system comprising a first electronic chip of manycore type according to one of the preceding embodiments interconnected to a second electronic chip of manycore type distinct from said first electronic chip is described.
- the first function is further implemented on a first cluster of said second electronic chip and the second function is further implemented on a second cluster of said second electronic chip.
- a system comprising a first electronic chip according to one of the preceding embodiments interconnected to a third separate multi-core type electronic chip of said first electronic chip is described.
- the first function is further implemented on a first core of said third electronic chip and the second function is further implemented on a second core of said third electronic chip.
- FIG. IA illustrates a component architecture of manycore type according to a first embodiment
- FIG. IB illustrates a component architecture of the manycore type in which clusters are linked point to point
- FIG. IC illustrates a component architecture of the manycore type in which clusters are connected by parallel bus
- FIG. 2 illustrates a component architecture of manycore type according to a second embodiment
- FIG. 3 illustrates a system comprising two components of the manycore type according to a particular embodiment
- FIG. 4 illustrates a system comprising two components, a manycore component and a component of the multi-core type, according to a particular embodiment
- FIG. 5 schematically illustrates a method of transmitting data between functions implemented on an electronic chip of the manycore type comprising a plurality of execution cores.
- Fig. IA illustrates a manycore component architecture according to a first embodiment.
- Each cluster includes a plurality of cores or computing units. Each core communicates with the other cores in the cluster through shared memory.
- the clusters C0 to C4 are interconnected with one another by at least two separate communication systems SI and S2. In one embodiment, the two distinct communication systems S1 and S2 are of different designs.
- the first communication system S 1 is shown in solid lines and the second communication system is shown in dotted lines S2.
- the manycore component can include other well known components not shown in FIG. IA (eg cache, memory, ROM, RAM, etc.).
- the first communication system SI ensures the deterministic routing of the data.
- This first SI communication system is typically of the point-to-point communication type (eg NoC, known by the French terminology of “network on a chip”). All the paths between the clusters being dedicated links, the routing of the data is guaranteed with a controlled latency.
- NoC is a technique for designing a communication system between clusters on the manycore component.
- a NoC type communication system applies network theories and methods to communications within the component.
- a serial bus NoC type communication system also has the advantage of being scalable. In particular, it makes it possible to multiply point-to-point links between clusters.
- the second communication system S2 does not provide this determinism in the routing of data. On the other hand, it offers the possibility of exchanges via various interfaces.
- This second communication system S2 is typically of the parallel bus type (e.g. AXI). In this second communication system, the routing of data is not guaranteed with controlled latency.
- Fig. IB illustrates such a point-to-point connection of the clusters C0 to C4.
- each couple of arrows represents a Buspp connection between two point-to-point clusters. Not all connections are shown.
- cluster C1 can also be connected to cluster C3 point to point by a NoC type bus.
- AXI is a protocol allowing the interconnection of clusters via a parallel bus. This protocol is part of the AMBA standard (acronym for “Advanced Microcontroller Bus Architecture”) developed by the company ARM Limited.
- the protocol simply establishes the rules of communication between the different modules (e.g. clusters) of a chip.
- Fig. IC illustrates such a connection of clusters C0 to C4 by a parallel bus.
- each couple of arrows represents a Buspar connection between a cluster and a Bdist distribution bar, ie a bus intended for the distribution of data on several types of interfaces (eg DDR, PCxpres, CAN, UART I2C, SPI, etc.) .
- the clusters C0 to C4 are interconnected with each other through the distribution bar Bdist.
- This P chip is advantageously used to implement avionics functions which require increased safety.
- the data in question are, for example, flight parameters such as the altitude of the aircraft, its speed, etc.
- a first function A eg monitoring of flight parameters is implemented on a first cluster C4
- a second function B eg managing flight controls, is implemented on a second cluster C0 distinct from the first cluster C4.
- the function B is also implemented on a third cluster C2 distinct from the first and second clusters C4 and C0.
- Function B implemented on cluster C2 is called a "redundant" function and is denoted B ". This is indeed the same function as function B implemented on cluster C0.
- function B implemented on C0 is stopped. Thanks to the "redundant" function B ", correct operation of the avionics system is maintained. Indeed, function A can continue to exchange data with function B 'implemented on cluster C2. The data is for example exchanged by passing from cluster C4 to cluster C3 and from cluster C3 to cluster C2. Data exchanges between C4 and C2 via C3 can be done through an internal communication system on the chip, e.g. NoC type.
- function B on two separate clusters C0 and C2 significantly improves the reliability of the avionics system.
- the function B is implemented on more than two distinct clusters in order to increase the redundancy and therefore the reliability.
- the failure of a data exchange link between two clusters, eg between C2 and C3, or else of the NoC type communication system as a whole can cause a stop of the avionics system or at least of certain functions which can be critical from a safety point of view.
- Fig. 2 illustrates a manycore component architecture according to a second embodiment.
- a single component or P chip there is a plurality of clusters, C0 to C4.
- Each cluster includes a plurality of cores or computing units.
- Each core communicates with the other cores in the cluster through shared memory.
- the clusters C0 to C4 are interconnected with each other by at least two communication systems SI and S2, e.g. of the NoC type and parallel bus.
- the same data are exchanged on two different communication systems, e.g. on a first system of NoC type and a second system of parallel bus type.
- the data exchanges via the first communication system are represented by arrows in solid lines and the data exchanges via the second communication system are represented by arrows in dotted lines.
- the second communication system makes it possible to maintain the exchange of data.
- function A implemented on C4 sends data to function B 'implemented on C2, it sends them via links L0 and L1 belonging to the first communication system and also via the L2 and L3 links belonging to the second communication system
- data exchanges can continue on the other link L0 belonging to the first communication system.
- function B ’ can optionally receive the same data twice, i.e. once for each communication system. Therefore, it can be decided that function B ’uses only the data received first and therefore ignores the same data that would be received second.
- priority may be given to one communication system over the other. Thus, if the priority is given to the first communication system and the function B 'receives data from the function A via these two communication systems, they use the data from the first communication system and ignore the data in origin of the second communication system.
- the data between two clusters is exchanged via more than two different communication systems in order to increase redundancy and therefore reliability.
- NoC and parallel bus type Communication systems of the NoC and parallel bus type are given by way of simple illustrative examples. Other communication systems operating under other communication protocols and allowing data exchange between clusters can be used instead of or in addition to NoC and parallel bus type communication systems.
- Fig. 3 illustrates a system comprising two manycore components according to a particular embodiment.
- the system comprises a first manycore component PI and a second manycore component P2, which are interconnected by at least two communication links La and Lb.
- Each component PI and P2 comprises a plurality of clusters, C0 to C4.

- Each core communicates with the other cores in the cluster through shared memory.
- the clusters C0 to C4 are interconnected with each other by at least two communication systems SI and S2, e.g. of the NoC type and parallel bus.

- the function A implemented on the PI component can exchange data with the function B implemented on the second component P2 thanks to the link La of a first communication system (eg of NoC type) or thanks to the Lb link of a second communication system (eg parallel bus).
- the components exchange data via at least two communication systems, eg of NoC type and parallel bus as illustrated in FIG. 3.
- the function B can also be implemented in the component P2 on another cluster distinct from C2 on which it is already implemented in order to increase the redundancy and therefore the reliability of the device. system.

- the function A implemented on the PI component can exchange data with the function B or B 'located on the same PI component according to the embodiments described with reference to Figs IA, IB, IC and 2.
- the function A implemented on the component PI can furthermore exchange data with the function B implemented on the second component P3 via a first communication system in using for example links Le, eg of Ethernet type or via a second communication system using for example links Ld, eg of PCIe type (acronym for “Peripheral Component Interconnect Express”).
