Abstract :
An approach to the realisation of 2D FIR filters based on a novel radix differential arithmetic is introduced. The differential algorithm is accomplished by coding the input video signal more efficiently using a DPCM coding system. Whereas the filter\´s coefficients are fed in digit serial fashion and specified using radix-2" arithmetic. The proposed approach provides a spectrum of architectures to allow a more flexible design trade off analysis between throughput rate and hardware cost
