A systolic realization for 2-D digital filters
M.A. Sid-Ahmed · IEEE Transactions on Acoustics Speech and Signal Processing · 1989
Systolic hardware realizations for two-dimensional finite-impulse-response (FIR) and infinite-impulse-response (IIR) digital filters are presented. The structure permits the 2-D input data to be scanned row-wise and broadcasted one value at a time to various processing elements. Shift registers are used to store the required data needed by the 2-D recursive equation. A processing element can be implemented in VLSI, and as many of these as are required to satisfy the order of the filter can be used to build the total structure.>
