A Multi-Synchronous UART Design D. Bhadra, V. S. Vij, and K. S. Stevens Abstract: Universal Asynchronous Receiver Transmitter (UART) implements serial communication between peripherals and remote embedded systems at high reliability and consists of two frequency domains. The multi-frequency nature of this peripheral favors its implementation using a multi-synchronous design methodology based on Relative Timing (RT). A full duplex UART which uses a novel multi-synchronous architecture is presented. This multi-synchronous design enables elasticity in the peripheral leading to power and energy benefits. Synchronous and multi-synchronous versions for the UART design were implemented and compared to illustrate the benefits of multi-synchronous design in terms of area, power, and energy. The synchronous UART consumed 4? the power of the multi-synchronous design at nearly the same area. |
