| Research Abstract |
High level design methodologies are becoming more and more important in the design of large system LSI devices. As a result, behavioral synthesis from C and other high level languages is key to achieving the productivity demanded by such large designs.
For memory intensive applications in particular, the automatic identification, optimization and synthesis of memory access operations is essential.
This research developed a method for automatically generating behavioral descriptions for memory access pipeline circuits. Combined with registerization, the approach can accelerate Memory Accesses (MA) irrespective of the degree of data reuse.
The method is applied to well-known algorithms used in applications such as speech recognition, JPEG encoding and particle tracking technology, and its effectiveness evaluated.
The number of MAs is reduced by over 20% and the overall performance improved by over 10% using these MA speed-up methods.
