Abstract

BWDSP is a word addressed VLIW DSP supporting clustering and SIMD.Based on open source compiling infrastructure open64

key technologies of compiler are developed for BWDSP which consist of optimized processing of address register

instruction clustering combined multi-heuristic factors

register allocation and instruction scheduling on clustering architecture.The key optimization technologies of BWDSP compiler on its hardware architecture include vectorization based on dependence analysis

application of effective instruction and recognization of zero overhead loop.Some general attention points for compiler development based on open source compiler infrastructure are presented after the development experience on BWDSP compiler is summarized.
