High speed, low power macrocell |
摘要 |
A macrocell for use in a programmable logic device (PLD) providing for enhanced logic capability and reduced setup time. The preferred embodiment of the macrocell includes two look-up tables, for increased fan-in, and two flip-flops that increase fan-out, thereby doubling logic capability of the PLD without unacceptably increasing device size. Doubling the register count makes this PLD particularly suitable for applications employing high density sequential logic. Furthermore, a second register can be used for receiving fast input signals form an input to the PLD to reduce setup time.
