In this paper we present 1D and 2D systolic
Distributed Arithmetic (DA) based structures that are designed
for the implementation of Finite Impulse Response (FIR) filters.
The paper compares the 1D DA based systolic structure with
1D systolic DA based decomposition method. The filters are
implemented on a Xilinx Virtex II Pro (XC2VP30) FPGA using
HDL and system metrics like Area, Gate Count, Maximum
Usable Frequency and Power consumption are estimated for
different filter orders and address lengths. The 1D systolic
decomposition structure is also compared with the existing
system generator implementation of DA FIR.. Results for an
exemplary implementation are presented.
