Programmable logic unit

An apparatus comprising:

• one or more input interfaces to receive one or more input signals;
• one or more first logic elements that are individually programmable to be one of a plurality of first functions;
• one or more second logic elements that are a decoder;
• one or more third logic elements that are individually programmable to be one of a plurality of second functions;
• one or more output interfaces to provide one or more output signals;
• and
• a programmable interconnect array that selectively forms one or more interconnections within a group comprising the one or more input interfaces, the one or more output interfaces, and the logic elements,
• wherein the programmable interconnect array is programmable in routing the one or more input signals to at least a portion of the logic elements, is programmable in routing one or more intermediate signals among at least a portion of the logic elements, and is programmable in routing one or more signals from at least a portion of the logic elements to produce the one or more output signals via the output interface.

A system comprising:

• processor unit configured to perform operations;
• and
• a programmable logic unit that is communicatively coupled with the processor unit, the programmable logic unit comprising:
• one or more input interfaces to receive one or more input signals;
• one or more first logic elements that are individually programmable to be one of a plurality of first functions;
• one or more second logic elements that are a decoder;
• one or more third logic elements that are individually programmable to be one of a plurality of second functions;
• one or more output interfaces to provide one or more output signals;
• and
• a programmable interconnect array that selectively forms one or more interconnections within a group comprising the one or more input interfaces, the one or more output interfaces, and the logic elements,
• wherein the programmable interconnect array is programmable in routing the one or more input signals to at least a portion of the logic elements, is programmable in routing one or more intermediate signals among at least a portion of the logic elements, and is programmable in routing one or more signals from at least a portion of the logic elements to produce the one or more output signals via the output interface.
