Description
Technical Field
The invention relates to the field of software radio, in particular to a multi-bus processor MHAL routing method in a software communication system structure.
Background
The Software Communications Architecture (SCA) provides an implementation-independent open architecture for the design of software radios. The SCA separates waveform application from bottom hardware and an operating system through a layered structure, provides a distributed processing environment through a CORBA technology, and realizes the portability of waveforms. In order to meet different communication service requirements, multiple processors are generally used in software-radio hardware platform design, and the various processors have great differences in architecture and programming mechanism, and support the CORBA to different degrees. The common processor only supports CORBA by general purpose processor GPP (general purpose processor), and the digital signal processor DSP and the field programmable gate array FPGA do not support CORBA generally. The following naming convention applies to processors: GPP stands for CORBA-capable processors (which may be CORBA-capable DSPs); DSP stands for a processor supporting C language, but does not support CORBA; FPGAs represent processors that support HDL, as well as CORBA. The software radio hardware platform is a heterogeneous processor platform consisting of a General Purpose Processor (GPP) and a special processor (DSP)/FPGA, and the difficulty of management and component interconnection and intercommunication is increased due to the difference of application development environments caused by the distributed heterogeneous characteristics of the platform, so that the flexibility of the system is limited. The current SCA specification provides a transparent data distribution mechanism for components on the general purpose processor GPP by means of CORBA middleware, i.e. a component on GPP can transmit data to another GPP component via CORBA without concern about the location of the other party and how the data is routed. But this is not applicable for special purpose processors like DSP/FPGA, since they do not directly support CORBA middleware yet, so the communication between DSP/FPGA components and GPP components and between components on different DSP/FPGAs depends on the modem level hardware abstraction layer MHAL specification. In the software radio based on SCA, communication between GPPs and inside is provided by CORBA middleware, and communication between GPPs and DSPs, between GPPs and FPGAs, between DSPs and between FPGAs is realized by a modulation and demodulation hardware abstraction layer (MHAL).
The MHAL specification is used to address platform independence of waveforms. MHAL is an underlying communications model that improves the portability of waveform components by providing standard protocols and interfaces to the underlying hardware and waveform components in different computing units on a hardware platform. MHAL specifies that a hardware abstraction layer performs data interaction In a packet switching mode, and each data packet has four fields of IU (In-Use), logical address LD (logical destination), length and Payload. When the information source program sends data, the information source program packs the data according to an MHAL message format, an LD field of the data packet is a logic address of the information sink program, and then a standard interface function Mhal _ Comm or a pushPacket function provided by the MHAL is called to send the data packet to a corresponding processor through a bus driving program. When the information sink program receives data, after the MHAL receives the data packet, the MHAL analyzes the logic address LD field of the data packet and calls the information sink program which is called and corresponds to the logic address LD field.
The MHAL specification defines standard API interfaces and message formats, and the description of data routing is simple, only specifying that routing functionality is required. The existing MHAL routing method includes: when the source program sends data, the MHAL searches a processor address PD (physical destination) operated by the sink program corresponding to the logic address of the sink program from the LD and PD mapping table according to the LD, and calls a bus driver by taking the PD as an input parameter so as to send a data packet to a processor corresponding to the PD. When the information sink program receives data, the MHAL searches for the corresponding callback information sink program from the LD and information sink program mapping table according to the LD and calls the callback information sink program. The existing MHAL routing method has the following disadvantages:
the existing MHAL routing method does not support a station system with multiple buses between processors.
The PD distribution in the existing MHAL routing method is according to a processor-PD, and a single-bus station system is arranged among the processors, so that the existing method can be adapted. In the current radio station system, a plurality of buses among processors are often involved, and a control bus and a data bus are typically coexisted. The control bus is generally low in speed but high in real-time performance and is used for transmitting control parameters. Data buses are typically high in speed, but not in strong real-time, and are used to transmit traffic data. In the existing MHAL routing method, one processor and one PD are used, when data is sent, only a data packet packed according to MHAL message format is transmitted to MHAL, MHAL can search for the PD according to LD, but one PD corresponds to two buses, and MHAL cannot know which bus driver is called. Therefore, the existing MHAL routing method cannot be used in a multi-bus station system between processors.
The existing MHAL routing method does not support a multi-port radio system of a processor.
When the existing MHAL routing method is used for sending data, only data packets packed according to MHAL message formats are transmitted to the MHAL, the MHAL can search the PD according to the LD, and the MHAL cannot determine which port of a bus to send the data packets, and cannot be used in a multi-port radio station system of a processor.
And thirdly, the existing MHAL routing method does not support packet routing forwarding.
The existing MHAL routing method is based on the condition of single bus full interconnection among processors, that is, each processor can access all other processors through a unique port of a bus, and does not consider the condition that the a processor is connected with the B processor, the B processor is connected with the C processor, and the C processor is not connected with the a processor, but the a processor needs to be communicated with the C processor, that is, the existing MHAL routing method does not support packet routing forwarding, which is often found in the existing radio system.

in the step of establishing a routing related information table, planning a physical address PD in advance according to a bus type and a bus port on a processor by taking the bus port as a minimum unit, and planning a logical address LD according to a waveform number, a component number and a port number, and on the basis, establishing a physical topology information table, a PD and bus driver mapping table, an LD and PD mapping table and an LD and sink program mapping table according to the connection relation of each bus port physical address PD between processors, the corresponding relation of each bus port physical address PD and a bus driver on each processor, the component deployment condition and the corresponding relation of each LD and a callback function;
in the step of sending data routing, a sending data routing function completes sending data routing, and the sending data routing function searches a processor bus port physical address destPD corresponding to the logic address of an information sink program from an LD (logical address) and PD mapping table according to the logic address LD by using three tables, namely a physical topology information table, a PD and bus driver mapping table and an LD and PD mapping table in a routing related information table; according to the destPD, searching a physical address nextPD of a corresponding next hop processor bus port and a physical address localPD of a corresponding local processor bus port from a physical topology information table; according to localPD, a bus driver corresponding to a bus port of a local processor is searched from a PD and bus driver mapping table, then, with nextPD as an input parameter, the corresponding bus driver is called so as to send a data packet to a processor corresponding to nextPD through a bus corresponding to localPD;
in the step of receiving data, a received data routing function completes received data routing, and the received data routing function forwards a data packet needing routing forwarding according to a sending data routing process by using an LD field in a routing related information table and an information sink program mapping table when receiving data; and the receiving data route searches a corresponding callback sink program from a mapping table of the LD and the sink program according to the logic address LD, if the corresponding callback sink program is found, the sink program is called to process the receiving data packet, otherwise, a sending data route function is called, and the data packet is forwarded according to a sending data route flow.
Compared with the prior art, the invention has the following beneficial effects:
inter-processor multi-buses are supported. The invention plans the PD with the bus port as the minimum unit according to the bus type and the bus port on the processor, and ensures that each port has an independent PD. When data is sent, a data sending routing function searches for destPD from an LD and PD mapping table according to the LD, searches for corresponding nextPD and localPD from a physical topology information table according to the destPD, and searches for a corresponding bus driver from a PD and bus driver mapping table according to localPD, so that when a data packet is sent by using a standard interface function Mhal _ Comm or pushPacket specified by MHAL specification, which bus used by the data packet can be determined for transmission. The problem that bus selection cannot be performed when a standard interface function Mhal _ Comm or pushPacket specified by an MHAL specification is used for sending a data packet in the conventional MHAL routing method is solved, and a multi-bus radio station system is supported among processors.
Multiple ports of the processor are supported. The invention plans the PD by taking the bus port as the minimum unit, looks up the corresponding nextPD and localPD from the physical topology information table according to the destPD, and looks up the corresponding bus driver from the PD and bus driver mapping table according to the localPD, thereby determining which port of which bus is selected to transmit data.

The invention solves the problem that the existing MHAL routing method does not support the routing and forwarding of the data packet.
