An Algorithm for FPGA based Implementation of Variable Precision MAC unit for High Performance Digital FIR Filters
نویسندگان
چکیده
The MAC Unit plays an important role in DSP applications. When implemented on FPGA, many MAC Units can be implemented on a single FPGA flexible to different design architectures. Hence the need of efficient MAC Units arises for filter applications. This paper discusses about variable precision based MAC Unit implemented on FPGA at algorithmic level. The proposed algorithm for FIR Filters is high performance and area efficient than the conventional MAC Unit. The delay for VP MAC Unit is reduced nearly by 60% than the conventional MAC Unit.

متن کاملDesign of IIR Digital Filter using Modified Chaotic Orthogonal Imperialist Competitive Algorithm (RESEARCH NOTE)
There are two types of digital filters including Infinite Impulse Response (IIR) and Finite Impulse Response (FIR). IIR filters attract more attention as they can decrease the filter order significantly compared to FIR filters. Owing to multi-modal error surface, simple powerful optimization techniques should be utilized in designing IIR digital filters to avoid local minimum. Imperialist compe...
