In this paper we present a CORDIC based FPGA implementation of Singular Value Decomposition for real time tactile information processing. The design is implemented to handle an arbitrary size two dimensional sensor input matrix. Besides the accuracy of the computation, implementation results figure out a relationship between used resources/latency and input data resolution: for each additional 1 bit input data resolution in the proposed case study, the average percentage slice logic utilization increases of 5.9%, and the average percentage clock cycles increases of 7.68%. This result demonstrates the necessity of computing the Singular Value Decomposition with fixed point arithmetic. Otherwise, silicon area and time delay will increase dramatically.
