Power-aware RAM Mapping for FPGA Embedded Memory Blocks

Free registration required

Executive Summary

Embedded memory blocks are important resources in contemporary FPGA devices. When targeting FPGAs, application designers often specify high-level memory functions which exhibit a range of sizes and control structures. These logical memories must be mapped to FPGA embedded memory resources such that physical design objectives are met. In this work a set of power-aware logical-to-physical RAM mapping algorithms are described which convert user-defined memory specifications to on-chip FPGA memory block resources. These algorithms minimize RAM dynamic power by evaluating a range of possible embedded memory block mappings and selecting the most power-efficient choice.
