A datapath is a collection of functional units such as arithmetic logic units (ALUs) or multipliers that perform data processing operations, registers, and buses. Along with the control unit it composes the central processing unit (CPU). A larger datapath can be made by joining more than one datapaths using multiplexers. A data path is the ALU, the set of registers, and the CPU's internal bus(es) th… WebAug 5, 2007 · The datapath width significantly affects the area and power consumption of processors, memories, and circuits.

WebBitwidth optimization of FPGA datapaths can save hard-ware resources by choosing the fewest number of bits re-quired for each datapath variable to achieve a desired qual-ity of result. However, it is an NP-hard problem that re-quires unacceptably long runtimes when using sequential CPU-based heuristics. We show how to parallelize the key WebMicrochip Technology
