A generalized algorithm with efficient architectures for high-speed parallel scramblers with reduced registers is proposed. The algorithm can be applied to any scrambler polynomials with three terms to achieve small numbers of registers and fan-outs. The critical paths only have one register and one XOR gate, which are merged into a dynamic differential circuit for implementation. The results show...
The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
Soft errors caused by ionizing radiation have emerged as a major concern for current generation of CMOS technologies and the trend is expected to get worse. Soft error rate (SER) measurement, expressed as number of failures encountered per billion hours of device operation, is time consuming and involves significant test cost. The cost stems from having to connect a device-under-test to a tester for...
In this paper, we present an automatic soft IP (Intellectual Property) generation method for high-speed Viterbi decoders. In our scheme, the synthesizable HDL (Hardware Description Language) code for the Viterbi decoder is automatically produced depending on not only the system parameters such as a coding rate but also the hardware architecture for parallel processing. The proposed method is implemented...
