Abstract
An associative signal processing apparatus for processing a plurality of samples of an incoming signal in parallel, the apparatus comprising: (a) an array of processors, each processor including a multiplicity of associative memory cells, the memory cells being operative to perform: (i) compare operations, in parallel, on the plurality of samples of the incoming signal; and (ii) write operations, in parallel, on the plurality of samples of the incoming signal; and (b) an I/O buffer register including a multiplicity of associative memory cells, the register being operative to: (i) input the plurality of samples of the incoming signal to the array of processors in parallel by having the I/O buffer register memory cells perform at least one associative compare operation and the array memory cells perform at least one associative write operation; and (ii) receive, in parallel, a plurality of processed samples from the array of processors by having the array memory cells perform at least one associative compare operation and the I/O buffer register memory cells perform at least one write operation.
