Abstract In recent years, the transmission speed of a cellular phone of the next generation has reached 100Mbps, and the transmission speed of optical communication amounts to 40 Gbps. Accordingly, demand for robust error correction code with high-speed processing of a Gbps class is increasing. The proposed code “High dimensional torus knot code” performs well in a field with many errors. In a performance comparison with the Reed-Solomon code, the performance of the proposed code is better than the Reed-Solomon code in an environment with 10-1-10-2 error. Moreover, doing a simulation in a CDMA communication environment, fluttering of error property has not occurred with the product code of convolutional codes (as inner code: the rate is 1/2) and the proposed code (as outer code: the rate is 0.53). Alternatively, under the same conditions, a fluttering error occurred in the Turbo cord. By applying the LSI technology, we developed ASIC of the proposed code, and FPGA for the high-speed MPEG communication device. We developed the three-dimensional, size-nine 3Dm9 and 4Dm5 chip. More specifically, the 3Dm9-code chip (developed in 2001) having a rate of 0.70 and block length of 729 bits was burnt onto a 100-kilogate, 0.35-micron-order LSI chip, and the 4Dm5-code chip (r=0.41, block=625, developed in 1999) was burnt onto a 50-kilogate, 0.6-micron-order LSI chip. Moreover, the 3Dm9-code chip was operated at a clock speed of 66.6MHz with throughput of 48Gbps. Finally, after applying the developed FPGA, the high-speed MPEG communication device can transmit a movie signal of 33Mbps.
