Wheel of. Reincarnation
Designing a display processor can become a never-ending cyclical process. In fact, we found the process so frustrating that we have come to call it the "wheel of reincarnation." We spent a long time trapped on that wheel before we finally broke free. In the remainder of this paper we describe our experiences. We have written it in the hope that it may speed others on toward "Nirvana."
