Instruction allocation device of high performance universal signal processor

Abstract

The invention relates to an instruction allocation device of a high performance universal signal processor. For the many-to-many condition of correspondence of a plurality of instructions to a plurality of execution units or channels in a high performance universal signal processor chip, the instruction allocation device realizes many-to-many automatic allocation and priority assignment by adopting the combination of an instruction core division module, an instruction classification module, an instruction allocation module and a multi-core instruction allocation integrated module so as to effectively solve allocation difficulties in the assignment of the execution units or transmission channels and that the plurality of instructions simultaneously occupy the same execution unit, finish the task of highly-efficiently, rapidly and rationally allocating all the instructions of the BWDSP100 chip and realize the full functions of operation execution resource occupation and transmission channel scheduling of the programmable very large scale digital signal processor (DSP) integrated circuit chip.

Description

technical field [0001] The invention relates to a high-performance general signal processor instruction distribution device. Background technique [0002] At present, digital signal processing chips have become the core components in high-speed automatic control, image processing, communication technology, radar and various signal processing. [0003] The development of domestic programmable VLSI IC chips is still in the preliminary trial stage, and the circuit design for the internal instruction distribution of VLSI chips with complex instruction sets, as well as the scheduling of execution units and bus channels is still to be solved. problem. [0004] The most widely used in the world at present is the TMS series of American TI Company and the TS series DSP chip of ADI Company. Two high-performance digital signal processing chips ADSP TS101S and ADSP TS20XS of ADI Company are more representative. The following compares the calculation execution unit inside the ADSP TS2...
