Configurable RS Decoder Design And Co-verification Use Hardware And Software

With the integration of mobile phone technology is increasingly high, Mobile TVhas attracted a lot of businesses since the2008Beijing Olympic Games. China SARFTCMMB and Korea T_DMA are used as the mobile TV standards. These standards arebased on RS as the outer code, LDPC as inner code to complete the encoding of thesignal, so the receiving port of mobile phone baseband must complete the decodingfunction of the signal. The RS codec realization is the focus of this thesis.This thesis is not only to complete the RS codec design, as well as efforts tocomplete the verification，verification is very important for IC, it always cost effortstwice than design.I participated in the RS codec algorithm study, C model implementation andverification, RS decoder RTL implementation in multi-mode, DUT area and poweroptimization. Area optimization implemented in two ways, ont way is modified the GFmultiplier form general to special, the area decrease from1962to293.Another way isshared the common component, the area reduced the fifth.A large number of randomstress test using System verilog DPI methodology.The contents of this thesis as follow:1. Implement and verify the algorithm using C language which supports threemodes RS(240,224), RS(240,192), RS(204,188), as a golden model for the followingup of hardware and software co-verification.2. According to the algorithm, design the hardware circuit, and the area and powerhave been optimized. Conventional design only support|L|=1in ME algorithm, thedesign it can support L to any value.3. Co-verification of the DUT and C golden model use the DPI methodology.Using code coverage and functional coverage detect the integrality of the verification.4. Do FPGA emulation.
