Abstract :
In this paper, we propose a new two-dimensional (2-D) systolic-array digital filter using a local broadcast scheme that is the hybrid of a modified reordering and another systolic transformation. This architecture occupies local broadcast, lower quantization error and zero latency without sacrificing the number of multipliers as well as delay elements under the accepted critical period. In addition, the widely used 2-D cascaded systolic digital filter can be described and reconstructed by a similar methodology
