AltiVec技术是PowerPC体系结构处理器采用的多媒体向量处理技术。研究和设计了支持该技术的128位可分裂式加法器。该加法器可分裂实现16个字节、8个半字、4个字的并行加法操作。从时序、面积以及验证的复杂度等方面对三种设计方法进行了分析比较。
AltiVec is a vector processing technology adopted by PowerPC processor.A fissile adder for it is presented.The 128- bits fissile adder can finish sixteen bytes add-operations or eight half-words add-operations or four words add-operations.h also provides the analysis of the timing,area and the verification complexity as to different design methods.
