Embodiment Construction

[0016] Multiprocessor shared peripheral circuit implementation method, each hardware accelerator is connected with a bus switch to switch the bus from different processors, the processor first sends a bus application when using the hardware accelerator, and the bus switch is based on the working state of the hardware accelerator Decide whether to allow the access of the processor; when a data processing and transfer of the hardware accelerator is completed, the processor issues a bus release command to allow the next use of the hardware accelerator;

[0017] For frequently accessed control register peripherals, use the bus synchronization circuit to merge the buses from different processors, synchronize the buses of each processor to the same clock domain, and merge the buses of multiple processors according to the order of priority Become a bus to access the control register peripherals, and ensure that multiple processors do not access the same control register peripherals at...

Abstract

Present invention discloses a multiprocessor shared peripheral equipment circuit implementation method and circuit. It contains Each hardware accelerator peripheral equipment connected with a bus switch for switching bus from different processor, processor sending bus applying in using hardware accelerator, bus switch determining whether allowing said processor visiting according to said modular work state, when hardware accelerator completing once data processing, processor sending bus release command for allowing next uses of said accelerator, multiprocessor bus adopting synchronous circuitmergence for frequent visited control register peripheral equipment, so realizing shared peripheral equipment data processing with simple circuit and reasonable design.

Description

technical field [0001] The invention relates to the technology of TD-SCDMA mobile phone digital baseband processing chip of time-division synchronous code division multiple access technology, in particular to a multi-processor shared peripheral circuit realization method and its circuit; it belongs to the technical field of communication electronics. Background technique [0002] The key to the realization of time-division synchronous code division multiple access technology TD-SCDMA mobile phone lies in the digital baseband processing chip, which is to complete the TD-SCDMA baseband digital signal processing function and the physical layer software, communication protocol stack, application layer man-machine interface MMI software operation core. This kind of chip usually adopts a multi-processor structure, uses a dual digital signal processor DSP to cooperate with a hardware accelerator to complete the signal processing of the physical layer, and uses an advanced reduced i...
