Abstract
A programmable logic device (PLD) includes programmable logic circuitry and a bridge circuitry. The bridge circuitry includes a first interface circuitry and a first signal select circuitry. The first signal select circuitry couples to the first interface circuitry and the programmable logic circuitry. The bridge circuitry further includes an information interchange circuitry. The first signal select circuitry is configured to selectably provide a communication path between the information interchange circuitry and either the programmable logic circuitry or the first interface circuitry.
Claims40
A programmable logic device (PLD), comprising:
- programmable logic circuitry;
- a bridge circuitry, comprising:
- a first interface circuitry;
- a first signal select circuitry, the first signal select circuitry coupled to the first interface circuitry and the programmable logic circuitry;
- and
- an information interchange circuitry;
- wherein the first signal select circuitry is configured to selectably provide a communication path between the information interchange circuitry and either the programmable logic circuitry or the first interface circuitry.
A programmable logic device (PLD), comprising:
- a bridge circuitry, comprising:
- a signal select circuitry;
- an interface circuitry, the interface circuitry configured to communicate with the signal select circuitry via a first set of at least one signal;
- and
- an information interchange circuitry, the information interchange circuitry coupled to the signal select circuitry;
- wherein the signal select circuitry is configured to selectably couple to the information interchange circuitry either the first set of at least one signal or a second set of at least one signal.
