Abstract
The present invention provides a centralized amplifier-accelerator a tri-state bus. The centralized amplifier-accelerator utilizes the module drivers as pre-drivers to the amplifier-accelerator. The centralized amplifier-accelerator is located physically in the center of the chip. This central amplifier-accelerator consists of a highly sensitive input sense circuit which detects voltage transition at very near the N-channel threshold for rising transitions and at very near the P-channel threshold for falling transitions. Once the sense circuit threshold is met, the output driver is triggered to drive the bus.
