ABSTRACT:
A multi-mode circuit for a self-timed integrated circuit is provided. The multi-mode circuit is programmable to operate in two or more modes, and is coupled to require, in each mode, receipt of a token on at least one of first, second, or third inputs before providing an output token. The multi-mode circuit is further coupled to require tokens on different inputs in at least two different modes. The multi-mode circuit can be an output circuit for a logic block in an integrated circuit including an array of interconnected logic blocks, where each logic block includes a logic circuit and a multi-mode circuit. One input of each multi-mode circuit can be programmably coupled to a select output of a multi-mode circuit in an adjacent logic block. Based on the programmed mode and the tokens received, the circuit routes data between inputs and outputs of the circuit.
