In this thesis, an approach is proposed for the design and implementation of a serial peripheral interface using Complex Programmable Logic Devices, (CPLD's). The focus of this research was to develop an effective Serial Peripheral Interface. The Serial Peripheral Interface, (SPI), created by Motorola is also known as Microwire, which is a trademark of National Semiconductor. The SPI is a full-duplex, synchronous, serial data link that enables communication between a host processor and peripherals.

The Serial peripheral interface can be programmed in software or built strictly in hardware inside a microcontroller. However, Complex programmable logic devices offer a quicker and more customizable solution. This research investigated the Serial peripheral interface with respect to its implementation in a CPLD and the use of the Very High Speed Integrated Circuit Hardware Description language, (VHDL).
