The Trim-Slice shipped with Ubuntu 11.04 for ARMv7 pre-installed. This is now out-of-date, but you can update against Ubuntu 11.10 (or 12.04 development) if you so choose. On TrimSlice.com the company offers documentation and source code for the device.
In this first Trim-Slice benchmarking article the performance of this Tegra 2 device in its stock configuration with Ubuntu 11.04 (as shipped by CompuLab) is being tested. Ubuntu in this way is also using softfp and not hardfp, but that will be compared in a future article too. In another article will be the results when playing around with the Trim-Slice under Ubuntu 11.10 and other Linux configurations. For comparison in this article are the earlier results from the PandaBoard ES and other hardware running Ubuntu 11.10. (As a reminder, the PandaBoard ES performance is expected to be improved under Ubuntu 12.04 where it has better support for the PandaBoard ES hardware.) This comparison includes the OMAP4660 PandaBoard ES, Atom N270, Atom Z530 (from the fellow Fit-PC2), Pentium M 1.86GHz, and Core Duo T2400 processor configurations.
