Design of a hardware efficient multiplier-less architecture for the computation of multi-dimensional convolution is presented in this paper. The new architecture performs computations in the logarithmic domain by utilizing novel multiplier-less log

modules. An effective data handling strategy is developed in conjunction with the logarithmic modules to eliminate the necessity of multipliers in the architecture. The proposed approach reduces hardware resources significantly compared to other approaches while it still maintains a high degree of accuracy. The architecture is developed as a combined systolic-pipelined design that produces an output in every clock cycle after the initial latency of the system. The architecture is capable of operating with a high speed clock frequency of 99 MHz based on Xilinx’s Virtex II 2v2000ff896-4 FPGA and the throughput of the system is observed as 99 MOPS (million outputs per second).
