Abstract EN
We address the automatic synthesis of DSP algorithms using FPGAs.
Optimized fixed-point implementations are obtained by means of considering (i) a multiple wordlength approach; (ii) a complete datapath formed of wordlength-wise resources (i.e., functional units, multiplexers, and registers); (iii) an FPGA-wise resource usage metric that enables an efficient distribution of logic fabric and embedded DSP resources.
The paper shows (i) the benefits of applying a multiple wordlength approach to the implementation of fixed-point datapaths and (ii) the benefits of a wise use of embedded FPGA resources.
The use of a complete fixed-point datapath leads to improvements up to 35%.
And, the wise mapping of operations to FPGA resources (logic fabric and embedded blocks), thanks to the proposed resource usage metric, leads to improvements up to 54%.
