Abstract :
A novel processor implementing Hewlett-Packard´s PA-RISC 1.1 (precision architecture-reduced instruction set computer) has been designed. A single chip implemented in a 0.8- mu m three-level metal CMOS technology includes the integer processor and a floating point coprocessor. The design operates at 100 MHz and is the first superscalar PA-RISC design. The processor cache is a large configurable memory implemented with industry standard SRAMs (static RAMs). High performance is achieved by high-frequency operation and a variety of techniques used to reduce the average number of cycles per instruction.<>
