Design and Implementation of a Platform for Embedded Multimedia Applications
Songping Mai · 2006
A platform for embedded multimedia applications is presented.Its design and implementation are described in detail.The proposed platform is an MIPS-based scalar RISC with Harvard micro-architecture,5-stage integer pipeline and enhanced multimedia processing capacity.It features a data path including non-aligned data access mechanism, two-dimensional DMA function and separated embedded instruction and data memories.This special architecture greatly promotes execution efficiency of boundary-crossed and block data access operations often found in multimedia processing.The prototype has been fabricated using UMC's 0.18-μm standard CMOS technology.
