1 Each term should be used in one and only one way throughout the dissertation.  The easiest way to avoid a long series of definitions is to include a statement: ``the terminology used throughout this document follows that given in [CITATION].'' Then, only define exceptions.
Serial Peripheral Interface Bus. The Serial Peripheral Interface bus (SPI) is a synchronous serial communication interface specification used for short distance communication, primarily in embedded systems. The interface was developed by Motorola in the late 1980s and has become a de facto standard. Typical applications include Secure Digital cards and liquid crystal displays.
and more straightforward than using SDRAM unless the system bus master provides the SDRAM interface module as mentioned above. This SDRAM controller reference design, located between the SDRAM and the bus master, reduces the userâs effort to deal with the SDRAM command interface by providing a simple generic system inter-face to the bus master.
