Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Two kinds of devices are involved in the system of the present invention: a master device and a slave device, wherein the master device refers to a device capable of actively issuing read and write commands in the system, such as a processor, direct memory access (DMA, Direct Memory Access), etc.; A slave device refers to a device in the system that cannot actively issue read and write commands, but can only passively accept read and write commands, such as: memory, peripheral controllers, etc.

[0045] Such as figure 1 As shown, the multiprocessor complete mutual access system of the present invention includes a multiprocessor module 11, an address mapping module 12, an on-chip interconnection bus 13, and a memory module 14; wherein,

[0046] The multiprocessor module 11 is used for processing and computing all data inside th...

Abstract

The present disclosure discloses a method of complete mutual access of multiple-processors. The method comprises: a separate boot memory and a separate address mapping module are allocated for each processor; the processors perform the mutual access in the multiple-processors through the address mapping module after the processors are booted. The present disclosure also discloses a system for enabling complete mutual access of the multiple-processors. The method and the system creates the advantage of allowing complete mutual access of the multiple-processors, thereby sharing address space in the multiple-processors, sharing the peripheral controller and memory, improving expansibility and performance of the system.

Description

technical field [0001] The invention relates to multiprocessor technology, in particular to a method and system for complete mutual access of multiprocessors in a system on chip (Soc, System on chip). Background technique [0002] With the advancement of integrated circuit (IC) technology and the rapid growth of embedded processing requirements, the processor system architecture is developing towards multi-core processors to solve the problems of high complexity and insufficient computing power of single processor systems. [0003] In the prior art, the processor division of labor in the multi-core processor system in the communication field is generally clear, and it is necessary to deal with multiple independent processing tasks. Each processing task is completed by an independent dedicated processing module, and a dedicated processing module is allocated to each dedicated processing module. Processor and peripheral set, each dedicated processor has its own independent add...
