The FPGA is ideally suited for an efficient implementation of the underlying finite field arithmetic. The software benefits the global control. We use a standard basis representation for the field elements and projective coordinates to implement the group operation. The results for area are comparable with existing hardware implementations. Although no attempts have been made yet to reduce the critical path delay of the hardware part, we obtained promising results towards speed and throughput. A clock frequency of 10 MHz is realized, but a lot more must be possible after optimization.","PeriodicalId":246898,"journal":{"name":"2001 IEEE Workshop on Signal Processing Systems. SiPS 2001.

However, the standard implementation of their decoding standard of their decoding algorithm suffers from a large latency and high power consumption making them improper for mobile interactive systems. To overcome this drawback, we systematically analyzed the maximum a posteriori algorithm, the key-building block of the decoder, and stated that memory accesses are the bottleneck. Therefore, we have systematically optimized the data transfer and storage. This paper presents the main results of this optimization, especially those concerning the memory organization and architecture. This optimization reduces the latency by a factor of 600 and the energy per bit by a factor of 20, allowing turbo codes application in future high-speed mobile systems.","PeriodicalId":246898,"journal":{"name":"2001 IEEE Workshop on Signal Processing Systems.

The proposed schemes impose to the direct form and achieve a certain reduction in the power consumption. A novel retimed structure and balanced modularized techniques are introduced and used to reduce the critical path to achieve hardware efficiency. A novel separated signed processing data flow scheme with modifying CSD (canonical signed digit) representation is also introduced and used to reduce the transition, which is the main source of power consumption. The combination of the proposed methods gives up to 71% reduction in power consumption with a slight area overhead.","PeriodicalId":246898,"journal":{"name":"2001 IEEE Workshop on Signal Processing Systems.
