ABSTRACT:
A method is provided for configuring an FPGA using a decoder implemented in the FPGA. Specifically, an external configuration device or an embedded non-volatile memory configures a first portion of the FPGA as a decoder. Encoded configuration data is transferred to the decoder, which then configures other portions of the FPGA. In one embodiment, the decoder is a decompression unit, which decompresses compressed configuration data. In another embodiment, the decoder is an interpreter, which interprets configuration commands. In some embodiments, the portion of the FPGA used for the decoder can be reconfigured after the configuration of the other portions of the FPGA.
