基于QEMU的TMS320C3X指令集架构仿真

Instruction set architecture emulator can assist developers to develop and test software more efficiently in the absence of relevant hardware devices, and has high practical value.Based on the most mature emulator framework QEMU in the open source community, this paper designs and implements an instruction set architecture emulator for TI\'s TMS320C3X floating-point DSP, and optimizes the algorithm according to its characteristics of not including virtual memory and suffering large overhead in emulation of floating-point arithmetic.Experiments show that, the QEMU-based TMS320C3X emulator achieves a fair amount of improvement in performance compared to the existing UNISIM emulator, with accuracy loss up to 0.1454%.
