ABSTRACT:
An FPGA includes an embedded non-volatile memory coupled to a configuration access port. The configuration access port allows the non-volatile memory to program the configuration memory of the FPGA. On power-on or reset, the non-volatile memory configures a first portion of the FPGA using configuration data stored in the non-volatile memory. Other portions of the FPGA can also be configured using the embedded non-volatile memory. Alternatively, an external configuration device can configure the other portions of the FPGA through a configuration port. Further, either the embedded non-volatile memory or the external configuration device can reconfigure the first portion of the FPGA.
