What's Reflex
...
Reflex is a suite of compiler and runtime support for applications to leverage low-power processors on mobile systems.
...
Reflex reliefs developers from dealing with the extremely asymmetric architecture. It not only manages deployment and execution of an application that is distributed over the main and the low-power processors, but also creates a software Distributed Shared Memory (DSM) across the distributed code. Essentially, Reflex provides a certain degree of programming transparency.

The Evolving Path
...
Reflex has been evolving. It is increasingly focused on facilitating third-party application development.
...
As of Mar. 2011, the Reflex codebase contains more than 10K lines of code, of which only less than 10% is reused/modified from the Dandelion codebase. The codebase is still growing.

Prototypes
We have just ported Reflex to TI pandaboard (based on TI OMAP4430 SoC). Picture source: TI.
The most recent Reflex hardware prototype built with Nokia N900 (based on TI OMAP3630 SoC), NXP LPC1768, and TI MSP430F1611.
The first geneartion Reflex prototype built with Nokia N810 and Rice Orbit Sensor.
An even earlier Reflex prototype built with Nokia N810, Rice Orbit Sensor, and CMUCAM3 camera.
