I. INTRODUCTION Power-related research activities at IBM's Austin Research Lab (ARL) include low power circuitry, power-efficient microprocessor designs, and server systems power measurement and management at many different levels. Researchers are given the opportunity to see their contributions at all levels of product design, since IBM produces its own microprocessors for its System p, i, and...

As we move towards several million transistors per chip it is desirable to move to higher levels of abstraction for the purposes of automated design of systems. Increasing performance of microprocessors in the marketplace is moving the balance between software and hardware. In this environment, it is necessary to adapt our tools to create systems, which encompass these fast microprocessors rath...

Instruction scheduling is a code reordering transformation that attempts to hide latencies present in modern day microprocessors. Current applications of these microprocessors and the microprocessors themselves present new parameters under which the scheduler must operate. For example, some multiple functional unit processors have partitioned register sets. In some applications, increasing the ...

Since the first introduction of the microprocessor, various kinds of microprocessors have been developed. There have been remarkable achievements both in the level of integration and processing speed. However, most microprocessors develqped to date are oriented to device control applications or low class minicomputer replacement. It is true that some bit-sliced microprocessors can operate at ve...

Modern microprocessors have sacrificed the exactness of exceptions for improved performance long ago. This is a side effect of reordering instructions so that the microprocessor can execute instructions which were not to be executed due to an exception. By throwing more circuits at the problem, microprocessors are designed so that they are able to roll back to the instruction causing the except...

The trend has been well established [Asanovic09]: parallel processors will dominate most if not every niche of computing. This move to parallelism was not a triumphant march forward to celebrate our success in creating productive and efficient software environments for parallel microprocessors. Instead it was a sudden retreat from the immediate danger of building powerinefficient microprocessor...
