| Abstract: | Source code analysis technology is an important processor design method,which is efficient in fixing the bottleneck of algorithm.The novel fine-grained code analysis technology extends the instruction set of an open source extensible processor OR1K by means of source code profiler,in terms of application of security application,and implements the extended instruction in mode of co-processor with base processor.The experimental result indicates that the extended processor has achieved 1.78 times increased processing efficiency at the cost of small chip area consumed. |
