The aim was the characterization of the performances of the dual core processor when used for executing a highly demanding lossless compression task, acting on data segments continuously copied from the static memory to the processor RAM. The selection of the compression activity to evaluate the performances was driven by the possibility of a comparison with previously executed tests on the Cobham/Aeroflex Gaisler UT699 LEON3FT SPARC™ V8. The results of the test activity have shown a factor 1.6 of improvement with respect to the previous tests, which can easily be improved by adopting a faster onboard board clock, and provided indications on the best size of the data chunks to be used in the compression activity. | Conference Name: | Space Telescopes and Instrumentation 2016: Optical, Infrared, and Millimeter Wave | Conference Place: | Edinburgh, UK | Conference Date: | 26 Giugno - 1 Luglio, 2016 | URI: | http://hdl.handle.net/20.500.12386/26407 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9904/1/Performance-analysis-of-the-GR712RC-dual-core-LEON3FT-SPARC-V8/10.1117/12.2232589.short?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510601871 9781510601888 |
