On-chip communication method of complex SOC

Abstract

The invention relates to an on-chip communication method of a complex SOC. The method comprises the steps that a main processor receives a to-be-solved signal, disintegrates a processing algorithm ofthe to-be-solved signal into multiple openCL invocations, and sends the openCL invocations to a communication and data management pool; the communication and data management pool sends the received openCL invocations to a communication loop in sequence; the openCL invocations are processed by all signal processing modules on the communication loop, then return to the communication and data management pool, and are collected by the communication and data management pool to be sent to the main processor. According to the on-chip communication method of a complex SOC, on the basis of unidirectional annular structure scheduling of the communication and data management pool, communication management when a large quantity of signal processing modules exist can be achieved, the processing modulesin the complex SOC can ensure the transmission efficiency during communication, the difficulty of star topology and bus topology structures during chip design is avoided, and the competition and conflict problems when multiple processing modules can complete the same openCL invocation are solved.

[0002] The rapid development of semiconductor manufacturing technology makes it possible to integrate larger-scale hardware resources on the chip. SoC tends to be a multi-core heterogeneous system chip composed of various types of CPUs, DSPs, and application-oriented hardware acceleration engines. Communication, the existing star and bus topology will have competition and conflict problems in the face of a large number of signal processing, and make the main processor overload, reduce the task processing capacity of the main processor, in addition, the existing communication Structural design is difficult, which is not conducive to expansion and openness. Therefore, it is urgent to redesign SOC communication, so as to transform from a calculation-based design to a communication-based design, and realize a scalable communication architecture.
