Audio processing and especially MP3 decoding is usually implemented by software due to the complexity of its hardware alternative. This work proposes a hardware solution to one of the most critical parts of an MP3 decoder, the polyphase filter bank. The aim is to improve its operation rate while saving power. The proposal takes advantage of the DSP-oriented architecture of modern FPGAs. Sequential...
Porting MP3 decoder effectively on a given hardware platform ADSP-BF533 EZ KITLITE is discussed in this paper [1]. Data structure layout, proficient data placement and data memory/cache handling for porting MP3 decoder are discussed. Hardware features and advanced instructions are availed for effective implementation of MP3 modules to reduce the MIPS. Results show MP3 decoder implementation consumes...
The authors present a hybrid hardware/software implementation for packetizing of MPEG-2 based video and audio ES to Transport Stream (TS). We have achieved one program TS packetization using DSP chips before. In that configuration, two 16-bit fixed-point DSP chips are needed for video and audio PES, TS packetization and formation, respectively (Yong Ji and Zhaohui Cai, 1998). In this design, we integrate...
