In the last few weeks, MIPS has already released the Linux Kernel for MIPS Android and shown us a low cost (99 USD) Android ICS Tablet. Today, they announced the official release of MIPS Android 4.0 source code.
The latest version of Android 4.0 is “mr0″ and you can read the release notes for further details.
Before downloading the Android source code be sure that you have a correctly setup Linux workstation.
Now, here are the instructions to checkout MIPS Android 4.0:
repo init --repo-url=git://github.com/MIPS/repo.git --repo-branch=stable -u git://github.com/MIPS/manifests.git -b mips-ics-mr0 -m mips-ics-4.0.1_r1m1.xml

If you just want to have a look, All MIPS Android source code can also be viewed online at http://www.github.com/mips.
MIPS also announced an optimized port of Myriad Dalvik turbo available for MIPS Android 4.0. This version of the Dalvik virtual machine is many times faster than the stock version of Dalvik that is available with the Android source code. You can see a short comparison in the video below. Bear in mind that is was done with Android 1.6 (in the video) and Android has improved a lot since then. Nevertheless, it should still be faster than the stock Dalvik engine in Android ICS.
You can get further information and download Dalvik Turbo on MIPS Dalvik Turbo page.
