Abstract
A data processing system is described in which the available technology is used to provide high performance. The high performance is achieved by having a four-level pipeline for the central processing system, a simplified instruction set and an interface with the coprocessor unit that has a simple and efficient interface with the normal instruction execution. The apparatus implementing the central processing system is closely connected to the instruction set. A discussion of the implementation of the data processing system is provided.
