New Partitioning Techniques in Hrdware-Software Codesign

하드웨어-소프트웨어 통합설계에서의 새로운 분할 방법

In this paper, a new hardware-software patitioning algorithm is presented, in which the system behavioral description containing a mixture of hardware and softwae components is partitioned into the hardware part and the software part. In this research, new techniques to optimally partition a mixed system under certain specified constaints such as performance, area, and delay, have been developed. During the partitioning process, the overhead due to the communication between the hardware and software parts are considered. New featues have been added to adjust the hierarchical level of partitioning. Power consumption, memory cost, and the effect of pipelining can also be considered during partitioning. Another new feature is the ability to partition a DSP system under throughput constraints. This feature is important for real time processing. The developed partitioning system can also be used to evaluate various design alternatives and architectures.
