Abstract
The MIPS processor is used in computer architecture courses in order to explain matters such as performance analysis, energy consumption, and reliability. Currently, due to the desire for more powerful computers, it is interesting to learn how to reallocate certain components in order to achieve heat reduction with low cooling costs. DEVS is a general formalism for modeling and analysis of discrete event systems based on set theory and represents a basis for discrete event abstractions by formalizing the concept of activity which relates to the specification and heterogeneous distribution of events in space and time. The MIPS simulator is built upon known techniques for discrete event simulation and its definition within a formal language such as DEVS provides completeness, verifiability, extensibility, and maintainability. In this chapter, the authors carry out a thermal analysis of the MIPS processor using a DEVS simulator and show a register reallocation policy based on evolutionary algorithms that notably decreases the resulting register bank temperature.
