Programmable Input And Output Interfaces In Processing Integrated Circuits For Servers And Other Devices

A method for operating a processing integrated circuit, the method comprising:

• configuring a first programmable interface circuit in the processing integrated circuit to transmit first information from a first hard logic circuit in a processing core of the processing integrated circuit to a first external terminal of the processing integrated circuit;
• and
• configuring a second programmable interface circuit in the processing integrated circuit to transmit second information from a second external terminal of the processing integrated circuit to a second hard logic circuit in the processing core of the processing integrated circuit,
• wherein the processing integrated circuit is one of a microprocessor, a central processing unit, or a graphics processing unit.

A processing integrated circuit comprising:

• a processing core comprising hard logic circuits;
• and
• a programmable interface circuit that is configurable to exchange signals between an external terminal of the processing integrated circuit and the hard logic circuits,
• wherein the programmable interface circuit comprises an input buffer circuit and an output buffer circuit, and wherein the processing integrated circuit is one of a microprocessor, a central processing unit, or a graphics processing unit.
