Abstract


The digital signal processor (DSP) is a dedicated processor for digital signal processing embedded . Series \In this paper, in-depth study on the basis of the architecture YHFT-DSP combined DSP development software and testing to achieve functional , designed to achieve a compatible JTAG (Joint Test Action Group) standard simulation / test parts . Simulation / testing components is an important part of the DSP hardware . Analysis domain parts by Simulation / Test Access Port ETAP ( Emulation / Test Access Port ) , the control domain access port the CDAP ( Control Domain AccessPort ) control domain CD (Control Domain ) , AD (Analysis Domain), the storage domain MD (Memory Domain ) and the boundary-scan register BSR (Boundary Scan Register) modules . Simulation / test parts support software debugging function : hardware and software breakpoints set and canceled the instruction pipeline control , CPUcore register file and storage space , reading and writing ; support test functions : sweep in and sweep out the value of the boundary-scan register full - chip scan testing . This paper analyzes the simulation / testing components function to complete the overall structure of the design , and extended the length of the instruction register of the JTAG standard simulation command a the accurate pipeline station boundary of simulation debugging control mechanism , to write all the RTL level code , and made ??design the complete module verification and system validation . The verification results show that this function properly , normal operation , and fully meet the predetermined design goals . Simulation / test parts used in YHFT-DSP chip design . The chip has been cast film production .
