Abstract
A processing integrated circuit includes a processing core comprising hard logic circuits and a programmable interface circuit configurable to exchange signals between an external terminal of the processing integrated circuit and the hard logic circuits in the processing core.
Claims20
A processing integrated circuit comprising:
- a processing core comprising hard logic circuits;
- a first programmable interface circuit that is configurable to exchange first signals between a first external terminal of the processing integrated circuit and the hard logic circuits;
- and
- a second programmable interface circuit that is configurable to exchange second signals between a second external terminal of the processing integrated circuit and the hard logic circuits, wherein the first programmable interface circuit is adjacent to a first edge of the processing integrated circuit, and wherein the second programmable interface circuit is adjacent to a second edge of the processing integrated circuit.
