DOWNLOAD PTLSIM

It seems that PTLsim has its own assumedpipeline structureand is not apparently tied to any actual implementation. PTLsim is used extensively at hundreds of major universities, industry research labs and the well known x86 microprocessor vendors Intel and AMD. Mauer 4 Estimated H-index: Published on Jan 1, Runs in user-space only , without any need for root access or the installation of any kernel module Ability to include pre-compiled libraries with the simulator Full debugging support using standard debuggers like GDB You can download the latest released version from Downloads page. People outside Intel and AMD cannot. PTLsim is very different from most cycle accurate simulators used in research applications.

A full system simulation platform.

Trends toward multi-threaded architectures, more complex micro-architectures, and richer workloads, make authoring detailed simulators increasingly difficult. Consequently, ptlsin accuracy of modeling a real processor relies on both the accuracy of the pipeline model itself, and the accuracy of adjusting the configuration parameters according to the modeled processor.

Additionally these processors are not designed to behave deterministically with respect to timing.

Experimentation – ACM SIGMICRO

It is not clear to me then how this differs from any other x86 Virtual machine technology such as QEMU, VirtualBox, VMWare or Virtual PC, which would be cycle accurate by virtue of actually directly running ptllsim on the hardware as well as running at core speeds.

Feel free to upvote, although Mackie 's answer seems better in general. Check out the FAQ, focus on their "co-simulation" technique.

These generate multiple streams of memory reference events that drive a user-provided memory system simulator. Measuring experimental error in microprocessor simulation.

Experimentation

Designers can execute programs on software models to validate a proposed hardware design's performance and correctness, while programmers can use these models to develop and test software before the real hardware becomes available. Simulators like PLTsim are designed for academic hardware developers who want to test new hardware features without spending hundreds of thousands of dollars on a new chip.

Yourst 5 Estimated H-index: For more documentations please visist Documentation page. Almutaz Adileh 5 Estimated H-index: Hard RTOS is hard to implement on x Compared to competing simulators, PTLsim provides extremely high performance even when running in full cycle accurate out of order simulation mode.

Using the microbenchmark suite We measure the experimental error that arises from the use of non-validated simulators in computer architecture research, with the goal of increasing the rigor of simulation-based studies.

Up to now, researchers have been using cycle-accurate simulators to evaluate ptksim PTLsim is very different from most cycle accurate simulators used in research applications.

I want to write a tools about pipeline analysis , can I get data I want from Intel?

Personal tools Log in. Unfortunately, today's processors are facing memory latencies in the order of hundreds of cycles. Asked 6 years, 8 months ago.

PTLsim models a modern superscalar out of order x processor core at a configurable level of detail ranging from RTL-level models of all key pipeline structures, caches and devices up to full-speed native execution on the host CPU.

The standard version runs any bit or bit single threaded userspace Linux application.

Thus, the complexity of such systems has been increasi In my mind they are not the same thing; bochs for example is a simulator rather than a VM, PTLsim appears to be somewhere in-between perhaps? The diversity in real-world processor designs mandates building flexible simulators that expose parts of the underlying model to the user in the form of configurable parameters. Published on Aug 1, This paper presents a phase-based profiling mechanism to speed up the process of learning how application behaviors perform on the hardware and vice versa.

Three critical requirements drive the implementation of a software model: Therefore, current processors spend most of their execution time stalling and waiting for long-latency cache misses to return from main memory Accelerated bulk memory operations on heterogeneous multi-core systems.
