Time multiplexing a plurality of configuration settings of a programmable switch element in a FPGA

摘要

A field programmable gate array (FPGA) system for time multiplexing a plurality of programmable configurations of the FPGA. The system includes a plurality of configuration memory cells which are loaded with configuration information. A time slice selector couples selected configuration memory cells to programmable switch elements that determine the configuration and function of the logic within the FPGA. A time slice controller determines which of the configuration memory cells the time slice selector couples to the programmable switch elements. The configuration memory cells may be implemented with half SRAM cells and the time slice selector may be implemented with P-channel transistors.
