32-Bit triple-emission digital signal processor supporting SIMD

Abstract

The invention discloses a 32-bit triple-emission digital signal processor supporting SIMD (Single Instruction Multiple Data), comprising three flow lines in parallel emission: a data access flow line, an integer arithmetic flow line and a vector arithmetic flow line, wherein each flow line is provided with an independent decoding and execution unit and supports SIMD operation. The 32-bit triple-emission digital signal processor supporting SIMD is mainly composed of a program memory interface unit, a data memory interface unit, an instruction fetch unit, a flow line control unit, a system bus, a data access flow line unit, an integer arithmetic flow line unit, a vector arithmetic flow line unit, a data register, an address register, a vector register, a coprocessor interface unit and a floating point arithmetic unit, all of which are connected together through a circuit. The 32-bit triple-emission digital signal processor supporting SIMD supports parallel execution of three flow lines so that the parallel processing capability of a DSP (Digital Signal Processor) is improved; besides, the 32-bit triple-emission digital signal processor supports parallel execution four groups of 16-bit multiplying and adding operations in a single cycle, and supports simultaneous execution of the operation of five groups of data and the access operation of one group of data; therefore, the data processing capability of the DSP is enhanced.

Description

technical field [0001] The invention relates to a digital signal processor, in particular to a 32-bit three-transmission DSP supporting SIMD. Background technique [0002] DSP can process digital signals in real time, has data processing capabilities far beyond general-purpose processors, and plays an important role in data communication, multimedia processing and other fields. With the high-speed development of communication technology and multimedia technology, the requirements for DSP data processing capabilities are getting higher and higher. The methods to improve DSP data processing capability mainly include increasing DSP main frequency, adopting multi-core architecture to enhance the processing capability of the whole circuit, adopting multi-transmission structure to enhance the parallel processing capability of DSP core, etc. At present, as the main frequency of DSP is getting higher and higher, the cost and difficulty of continuing to increase are also getting hig...
