System, apparatus and method for adaptive operating voltage in a field programmable gate array (fpga)

A method comprising:

• receiving, in a field programmable gate array (FPGA) having at least one programmable logic circuit, a bitstream and metadata associated with the bitstream;
• programming the at least one programmable logic circuit with the bitstream to enable the at least one programmable logic circuit to execute a function;
• executing at least one self-test for the function in the FPGA at a first voltage, the metadata to identify the at least one self-test and the first voltage;
• determining if the execution of the at least one self-test meets a performance threshold;
• and
• causing the FPGA to operate at the first voltage in response to determining that the execution of the at least one self-test meets the performance threshold.

An apparatus comprising:

• a system on chip including at least one core and at least one field programmable gate array (FPGA), the at least one FPGA comprising:
• a plurality of programmable logic circuits each to execute a function programmed with a corresponding bitstream;
• at least one self-test circuit to execute one or more self-tests at one or more first voltages, the at least one self-test circuit to be programmed with metadata associated with the corresponding bitstream;
• and
• a power controller to identify a minimum operating voltage for the plurality of programmable logic circuits based on the execution of the one or more self-tests.
