Multiplication is a significant process in digital signal processing algorithms. These algorithms involve large number of multiplications, which is time consuming. In digital signal applications time is more important as compared to accuracy. In this paper a simple and efficient architecture of multiplier is proposed which uses adders, shifters, encoders and decoder etc. that consume less area, time...
This article presents a generator of floating-point exponential operators targeting recent FPGAs with embedded memories and DSP blocks. A single-precision operator consumes just one DSP block, 18 Kbits of dual-port memory, and 392 slices on Virtex-4. For larger precisions, a generic approach based on polynomial approximation is used and proves more resource-efficient than the literature. For instance...
In many DSP applications (image and voice processing, baseband symbol decoding in high quality communication channels) several dBs of SNR loss can be tolerated without noticeable impact on system level performance. For power optimization in such applications, voltage overscaling can be used to operate the arithmetic circuitry slower than the critical circuit path delay while incurring tolerable SNR...
