Design and Analysis of Serial Peripheral Interface for Automotive Controller

Serial Peripheral Interface (SPI) is a commonly used communication protocol that allows serial data transfer between a master and a slave device over a short distance. However, the current implementation of the Serial Peripheral Interface has a low speed and clock synchronization issue. When it comes to automotive, there a few things that are needed to be taken into consideration to increase the performance of the interface device. The paper present the design, simulation, verification and optimize SPI based on automotive interface device specifications. This includes a higher speed for the interface device and the efficiency of power dissipation. The SPI has been successfully optimized with a 1000MHz speed, a power of $575.7694 \mu \mathrm{W}$ and a total area of 1102.81mm2. The speed and area achieved are well improved over the current design of SPI. Even though the total dissipation achieved is above the current implemented SPI design, it is acceptable due to the technical relation between power and speed in VLSI design.
