Summary
Distributed Arithmetic (DA) is a high speed multiplication technique used for implementation of digital filters and signal upconversions. The DA is bit serial word parallel approach where throughput rate does not depend on flter length or data ste. In this paper a serial DA method is employed for FPGA implementation of digital component of the TIGER transmitter. A prototype has been synthested and mapped using Xilinx Virtex II. The design with fourteen bit 100 tap FIRfirter and upsanipling ratio of eight takes only 18% of the device. Performance of the DA modulator is discussed with variable filter length and precision level.
