The architecture of this processor is based on the CS arithmetic,also combines pipeline process and parallel process to reduce process time,and combines fixed point operation and floating point operation to reduce hardware resource.
该处理器的体系结构由算法直接映射而来,同时根据算法内在的时间关系将流水处理和并行处理相结合,从而极大地减少了处理时间。 根据算法各运算对数据的精度要求不同,将浮点运算和定点运算结合在一块,既满足了成像的精度要求又节省了硬件开销。
