Abstract

INTRODUCTION: When it came time to begin thinking about testing a new device that connected on the DFCI (Device Function Controller Interface), I took a look at the test drivers that were available and decided that there was nothing that would run sufficiently fast to test the device at anything that remotely resembled the speeds the device would be subjected to on the interface when driven by a host processor. Also, there was nothing that was easy enough to understand for the average person to write test cases for the device to be tested. All of the device drivers at the time ran on the IBM PC (or compatible) through a special DFCI adapter card.
