Digital System Design

In some modules of digital systems, such as Fast Fourier Transform (FFT), Discrete Fourier transform (DFT), IQ (in-phase and quadrature components) modulation/ demodulation, the outputs use the complex data formed , and the calculation of its magnitude value √ are required. In software digital signal processing platform, the multiplication and square root operations are executed by using its math library; however, in Application specific integrated circuit (ASIC) digital system design, the implementation of those operators via Coordinate Rotation Digital Computer (CORDIC) algorithm requires the numerous resources and delays. So, in this paper, we present a fast approximation method for above problem which takes a small delay but acceptable accuracy for AISC digital system design. Keywords—ASIC, Digital system design, FFT, DFT, Fast amplitude approximation, Max-Min approximation.

With the continuous improvement of the complexity of the microelectronic system, its reliability risk is becoming more and more obvious. In order to improve the reliability of electronic systems in complex electromagnetic environment, this paper proposes a new fault self-repairing method; the idea is to realize controllable silicon evolution on the FPGA. A MicroBlaze CPU and VRC array are designed, and the CPU runs the evolutionary algorithm to configure the VRC array, dynamically changing the structure and function of the circuit, so as to obtain high reliability of the digital fault self-repairing circuit. Evolving fault self-repairing technology provides a new way for the high reliability of the digital system design.
