Design of Hardware Loops for Audio-Specific DSP Core
Yiwen Wang · 2008
Design of hardware loops for an audio-specific DSP core was presented,which could implement both single-instruction and multi-instruction hardware loops with the same hardware architecture and loop instructions, and up to 4 nested loops were allowable.The proposed design was verified based on FPGA platform.It has been demonstrated that the hardware loop architecture can perform repetitive execution of instructions accurately and efficiently. The design provides necessary support for audio decoding based on audio-specific DSP core.
