High Performance and High Efficiency Memory Management System for H.264/AVC Application in the Dual-Core Platform
2006
This paper proposes memory management system for multimedia application based on dual-core platform. To use memory bus bandwidth efficiently and reduce memory bus transition, two steps store optimization in control level is adopted and bus efficiency increases nearly 35% compared with former scheme. To harmonize different master requirement, reasonable schedule level arranges memory access priority. Under these two levels, memory controller can cope with H.264 HDTV decoder 1920times1080 @ 30 frames per sec real time access clocking at 100 MHz. Moreover, this VLSI design is convenient to be integrated into different multimedia processing platform
