Linearly scalable finite impulse response (FIR) filter

摘要

The present invention provides an improved Finite Impulse Response (FIR) filter providing linear scalability and implementation without the need for delay lines, comprising a multiprocessor architecture including a plurality of ALUs (Arithmetic and Logic Units), multipliers units, data cache, and load/store units sharing a common instruction cache, and multi-port memory, and an assigning means for assigning to each available processing unit the computation of specified unique partial product terms and the accumulation of each computed partial product on specified output sample values. A method is also provided for implementing an improved Finite Impulse Response (FIR) filter providing linear scalability using a multiprocessing architecture platform without the need for delay lines.
