Memory efficient software synthesis form dataflow graph
Wonyong Sung, Junedong Kim, Soonhoi Ha · International Symposium on Systems Synthesis · 1998
Due to the limited amount of memory resources in embedded systems, minimizing the memory requirements is an important goal of software synthesis. This paper presents a set of techniques to reduce the code and data size for software synthesis from graphical DSP programs based on the synchronous dataflow (SDF) model. By sharing the kernel code among multiple instances of a block, we can further reduce the code size below the single appearance schedule. And, a systematic approach is presented to give up single appearance schedules to reduce the data buffer requirements. Experimental results from two real examples prove the significance of the proposed techniques.
