The programmable digital convolver provides an example of a sophisticated processor, developed for a particular function.
However, the sophisticated digital convolver which is optimized for one function still lags behind the computational performance of the SAW convolver.
Wiatr et al [7] implemented FPGA based convolver and calculated that number of CLBs required to implement RBs is even more than CLBs required for implementing rest of the system i.e.
In a CMC configuration, the first convolver linearly time-skews the frequency components of wideband signals to counter the time-skewing that occurs in the second convolver.
The CR may be implemented in one of two basic algorithms, Figures 1 and 2, typically designated as M(L)-C(S) and M(S)-C(L),[4] but here simplified to long multiplier and long convolver, respectively.
Each convolutional layer contains several different convolvers (filters) and these convolvers make observation to all partial features of the signal.

This is mostly due to the use of expensive FFT-based convolvers in the acquisition process.
Prior to joining Sawtek, Almar was with COM DEV in Canada and Plessy Research in England, where he had responsibility for the design and implementation of SAW convolvers, resonator filters and SAW dispersive delay lines for pulse compression systems and microscan receiver subsystems.
