Soft IP Compiler for a Reed-Solomon Decoder

Abstract

In this paper, we present a soft IP compiler for the ReedSolomon decoder that generates a fully synthesizable VHDL core exploiting characteristic parameters and design constraints that we newly classify for the soft IP. It produces a structural design with an estimable regular architecture based on a finite state machine with a datapath (FSMD). Since characteristic parameters provide different design points on the design space, using one of two simple procedures called the constructive search with area increment (CSAI) and constructive search with speed decrement (CSSD) for design space exploration, the core compiler makes it possible for an IP user to create the Reed-Solomon decoder with appropriate sub-architectures without synthesizing many models. Experimental results show that the IP compiler can apply to several industry standards.

RTL development of a parameterizable Reed–Solomon Codec

“…Timing analysis was neglected in that work, an important metric that defines whether a given architecture meets or not throughput requirements of the targeted application. Park et al covered such an aspect by proposing a Soft IP compiler for RS decoders that is capable to search a RTL architecture which is closest to user area and throughput needs [29]. It concentrates more on the algorithm used to generate the IP, and the aspects of the RTL development of parameterizable RS codecs were not a centrepiece in that work.…”

Design of Encoder and Decoder for LDPC Codes Using Hybrid H-Matrix

“…The bit-error-rate (BER) can be reduced without increasing the signal power since the transmitted data carry redundancies that are used to detect and correct errors. This coding skill is useful in transmission on finite power channels such as general switched telephone networks [2]- [5].…”
