Abstract. The excellent performance of the contemporary x86 processors is partially due to the complexity of their memory architecture, which therefore plays a role in performance ...
In this paper, we introduce PTLsim, a cycle accurate full system x86-64 microprocessor simulator and virtual machine. PTLsim models a modern superscalar out of order x86-64 proces...
Current superscalar processors, both RISC and CISC, require substantial instruction fetch and decode bandwidth to keep multiple functional units utilized. While CISC instructions ...
In this paper we describe the design and implementation of a flexible, and extensible, just-in-time ARM simulator designed to run co-operatively with a multi-core DSP simulator on...
Current trends in processor design are pointing to deeper and wider pipelines and superscalar architectures. The efficient use of these resources requires speculative execution, ...
