Embodiment Construction

[0031] Such as figure 1 As shown, the performance evaluation method of the general processor in this embodiment includes:

[0032] 1) Divide the test program into multiple execution phases;

[0033] 2) Select a sequence of instructions from each execution stage as a test sample and calculate the weight;

[0034] 3) Run the test program on the real processor chip platform, and use the checkpoint creation tool to generate checkpoints for each test sample;

[0035] 4) Use the checkpoint recovery tool to restore the generated checkpoint on the test verification platform, and restore a certain number of instructions and collect performance data on the simulation verification platform;

[0036] 5) Calculate the performance data of the entire test program based on the weight of each test sample and the performance data of its corresponding checkpoint.

[0037] Such as figure 1 As shown, the detailed steps of step 1) in this embodiment include:

[0038] 1.1) Use program dynamic a...

Abstract

The invention discloses a performance evaluation method for a universal processor. The method comprises the following steps: dividing a test program into a plurality of execution stages; a section ofinstruction sequence is selected from each execution stage to serve as a test sample, and calculating the weight; running a test program on a real processor chip platform, and generating a check pointfor each test sample by adopting a check point creation tool; recovering and executing a certain number of instructions on the simulation verification platform by using check points recovered and generated by a check point recovery tool on the test verification platform, and collecting performance data; and calculating the performance data of the whole test program according to the weight of eachtest sample and the performance data of the corresponding check point. The performance can be evaluated quickly and accurately, and various simulation verification platforms and flexible and fine-grained performance evaluation are supported.

Description

technical field [0001] The invention relates to processor evaluation technology, in particular to a performance evaluation method of a general processor. Background technique [0002] Generally, evaluating the performance of a processor requires running some benchmark programs to obtain the processor's performance score. These benchmark programs include SPEC2000, SPEC 2006, Linpack, CoreMark, etc. Typically, these tests are performed on actual processor chips, so even large test suites, such as the SPEC 2006ref test suite, can obtain test results within hours. However, chip manufacturing is a huge investment project, and once the tape-out starts, the original design of the chip cannot be modified. Therefore, chip design companies need to fully verify chip performance from the early stage of design until the design code is submitted to ensure that the designed chip can achieve the expected performance goals. [0003] At present, the pre-verification methods of processor ch...
