Impact of Bit-Width Specification on the Memory Hierarchy for a Real-Time Video Processing System

Bit-width specification will affect the total memory storage requirement of a video processing system. However, what is not so obvious is that the bit-width specification will also affect the design of the memory hierarchy. Experiments with a real-life surveillance system show how the optimal alloca...

Summary:Bit-width specification will affect the total memory storage requirement of a video processing system. However, what is not so obvious is that the bit-width specification will also affect the design of the memory hierarchy. Experiments with a real-life surveillance system show how the optimal allocation of shift registers for the storage of intermediate results is sensitive to bit-widths. It is shown that the total on-chip memory storage requirement can be reduced by 61 percent compared to a non-optimal design
