The latest proposed Ethernet standard is 10GBASE-T or 10 Gigabit Ethernet, which achieves a data rate of 10 Gigabits per second (Gbps). This is intended to meet the ever-increasing demand for data rate and bandwidth. The high frequencies involved in the 10GBASE-T standard give rise to a new type of crosstalk in data cables, which was not an issue in earlier(More)
The inverse discrete cosine transform (IDCT) is a significant component in today's JPEG and MPEG decoders. Of all the stages in the decoding process of a JPEG file, the IDCT is the most computationally intensive. Hence, we require fast and efficient implementations, either in software or hardware. Numerous individual designs for computing the ID-IDCT have(More)
A new class of iterative bit flipping (BF) decoding algorithms adapted for low-density parity check (LDPC) convolutional codes is proposed. Compared with Gallager's original BF algorithm, the new BF algorithms improve both the coding gain and the error correction speed. At a bit error rate (BER) of 10 , the best of the new bit-flipping algorithms achieves,(More)
In this paper, we introduce low density parity check convolutional code (LDPC-CC) parallel encoder and decoder algorithms for the XInC MIMD multi-threaded microprocessor. A modified memory-based decoder architecture and an interleaved LDPC-CC code scheme are also proposed. Extensions and simple modifications to the current XInC microprocessor are proposed(More)
Low density party check (LDPC) codes are among the most powerful error control codes known. They can produce error correcting performance close to the Shannon limit and can be decoded using iterative decoding algorithms with linear complexity. These key advantages have made LDPC codes a candidate coding scheme for various novel applications and standards,(More)
