ABSTRACT:
In one embodiment of the invention, a programmable logic device such as an FPGA includes a programmable fabric; a JTAG interface operable to receive configuration data for programming the fabric; a SPI interface operable to receive and transmit configuration data for programming the fabric; and circuitry coupled to the JTAG and SPI interfaces. The circuitry is operable, without being configured, to transfer configuration data received at the JTAG interface to the SPI interface for transmission to an external device having a SPI interface, such as a serial flash memory.
