Abstract :
In this paper we show how the High Level Synthesis (HLS) tool can efficiently be used for DSP ASIC development. The performance of general HLS tool is improved with simple transformations and code optimizations, and a direct mapping to technology optimized parameterizable ASIC Register Transfer Level (RTL) library. The library mapping contains three phases: a structure recognition, an architecture selection and a parameter optimization. As an optimization framework SYNT, Synopsys and Matlab design environments are integrated. Lsi10k and Xilinx 4000 series are used as target technologies to demonstrate the performance of the approach
