32-bit RISC Microprocessor for Digital Media Player
INTRODUCTION
Preliminary
1-1
1 INTRODUCTION
The TCC76x is a system LSI for digital media player based on the ARM940T, ARM’s proprietary 32-bit RISC CPU
core. It can decode and encode MP3 or other types of audio/voice compression/decompression standards by
software based architecture. The on-chip USB controller enables the data transmission between a personal
computer and storage device such as NAND flash, HDD, CD etc.
