Abstract: |
A method based on VSIPL API is proposed to solve the problems such as
bad portability and reusability of embedded information processing in aerospace
and communication field to improve portability and reusability between various s
ystems and platforms. By AltiVec technique of Power-VSIPL, data-parallel desig
n and loop unrolling optimization, the middleware can insure precision and incre
ase effectiveness by 1~5 times. |
