Abstract: For clock shared a multithreaded processor(SMT_PAAG)of instructions and data transfer rate indemand, proposes a shared clock multithreaded processor cross storage structure.The structure is composed of data storage and instruction cross storage.The data storage exchange between the front processing unit and the multi thread processing unit(Element Processing, PE)is realized, data interactions between threads, and thread the internal data access.Instruction cross storage to achieve the PE internal thread instruction access.Implemented on the FPGA results show that the cross-storage structures can meet a multithreaded processor for instructions and data transfer rate of the demand, the highest frequency can reach 518.309 MHz.
