Design of the Hermes-RISC processor

This paper presents the structural design and the functional characteristics of a RISC processor called Hermes-RISC. The design of the Hermes-RISC processor is based on the study and evaluation of a variety of assembly instruction sets. The Hermes-RISC is a pipeline superscalar RISC processor with four superscalar units. The first stage evaluation of the Hermes-RISC performance is also presented here. This evaluation is based on the execution of a set of primitive processing tasks, such as summation, multiplication of numbers, multiplication of matrices, sorting, finding maximum values among a set of numbers, procedure calls, etc. Moreover, the performance of Hermes-RISC is compared with a variety of RISC processors.
