Abstract EN
This paper presents an automated tool for floating-point to fixed-point conversion.
The tool is based on previous work that was built in MATLAB/Simulink environment and Xilinx System Generator support.
The tool is now extended to include Synplify DSP blocksets in a seamless way from the users' view point.
In addition to FPGA area estimation, the tool now also includes ASIC area estimation for end-users who choose the ASIC flow.
The tool minimizes hardware cost subject to mean-squared quantization error (MSE) constraints.
To obtain more accurate ASIC area estimations with synthesized results, 3 performance levels are available to choose from, suitable for high-performance, typical, or low-power applications.
The use of the tool is first illustrated on an FIR filter to achieve over 50% area savings for MSE specification of 10−6 as compared to all 16-bit realization.
More complex optimization results for chip-level designs are also demonstrated.
