Abstract :
Two components for image compression which provide almost all the computational power required by today´s efficient codecs for full motion image compression are presented. The first component computes 8×8 discrete-cosine transform and zigzag conversion of coefficient scanning for a pixel rate up to 27 MHz. The second component computes full-search motion estimation for a pixel rate up to 18 MHz. System implementation for image compression is discussed
