Research And Realization On The VLSI Design Critical Technologies Of Microprocessor Systems Peripheral Interface Controllers

Embedded systems have been widely applied to military affairs, economy and other areas of society. Embedded Microprocessors play an important role in embedded systems. With the development of very large scale integration circuit (VLSI), more and more transistors could be integrated in a single chip, and the technologies of System on Chip (SOC) emerge as the times require. Not only the high performance microprocessor core could be integrated in an embedded microprocessor chip, but also various peripheral device interface controllers could be integrated in the same microprocessor chip. This would result in many advantages for embedded systems, such as increasing reliability, decreasing design complexity and reducing cost. Based on the requirements of embedded microprocessor system chip applications, the research on critical VLSI realization technologies of many peripheral device interface controllers in a 32-bits high performance embedded microprocessor systems chip has academic and practical signality.This thesis focus on the critical VLSI design and realization technologies of many peripheral device interface controllers in a 32-bits high performance embedded microprocessor systems chip. These peripheral device interface controllers include LCD, UART, I~2C, SPI and PTC. Base on the research of low power design technologies, this thesis proposes a low power LCD controller architecture. The low power LCD controller has been designed and implementated. It is a general purpose LCD controller, and could support many display modes. After analyzing many the specifications of many peripheral device interfaces, this thesis have been done much work on the VLSI desing and implementation technologies of these interface controllers. Several common used interface controllers have been implemented. In addition, "Tengyue-I" 32-bits high performance embedded microprocessor system chip development plateform has been implemented. The completely functional verification and performance test have been done for the realized chip and various peripheral device interfaces. The verification and test results have proven the work of this thesis is correct and effective.
