Abstract

In this paper we address the time-constrained architectural synthesis of fixed-point DSP algorithms using FPGA devices. 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); and, (iii) a novel resource usage metric that enables the wise distribution of logic fabric and embedded DSP resources. The paper shows: (i) the benefits of applying a multiple wordlength approach to the implementation of fixedpoint datapaths; and (ii) the benefits of a wise use of embedded FPGA resources. The proposed metric enables area improvements up to 54% and the use of a complete fixed-point datapath leads to improvements up to 35%.
