Abstract

The invention discloses an ASIP based on an extensible processor architecture and a realizing method thereof, which mainly solve the problem of high circuit complexity and large resource consumption in the prior art. Aiming at the extensible processor architecture after optimization, the invention adopts a five-level-pipeline realizing method, and adopts a data orientation technology and a branch non-execution strategy to solve data hazards and control hazards in pipeline treatment respectively. The ASIP comprises an instruction fetch unit, a decoding unit, an execution unit, a memory access unit, a write-back unit, a pipeline control unit, a timer and an interrupt controller. According to the ASIP and the method, the characteristics of a pipeline processor and an FPGA (field-programmable gate array) are considered sufficiently, the pipeline structure is partitioned reasonably, and the hardware resources of the FPGA are utilized to the utmost extent; and the ASIP and the method have the advantages of simple circuit design, low resource consumption, high processor performance and low power consumption, and are highly suitable for large-scale parallel processing.
