RESUMO
The constant reduction in size and consequential increase in number of transistors inside a chip causes an exponential growth in digital circuit power consumption. Combined with the growing demand for portable electronic devices, this has led to a rising concern about energy consumption. The more power is dissipated, the more heat is generated, and the more energy is spent in the cooling process. As a result, designers have been more and more considering the impact of their decisions on this matter. Currently, ADLs¹ are being used to design new processors. These languages describe the architectural behaviour for each action or instruction. Besides decreasing the time-to-market gap, ADLs are useful in discovering architectural problems at a higher leveI. This work presents an instruction leveI power estimation tool that uses ArchC ADL as a base, and a SPARCv8 processor as a case study. By using the developed tool, a simulation of a program with estimated power consumption can be accomplished 100 times faster, in average, than the traditional tools
