There are a lot of cool things about the G1, but most people don’t talk about he hardware very often. It has a pretty snappy CPU, a good amount of RAM, and expandable storage. The coolest thing about the CPU is that it is a CPU/GPU dual-core combo unit. That gave me some ideas.
I know that Apple is working on their OpenCL that will allow applications on Mac OS X Snow Leopard to leverage the GPU for tasks that use it to advantage, like say floating point math, etc… It abstracts away all of the lower level coding that one would normally have to do for this type of functionality. Nvidia has some APIs for this type of programming, and I believe that Intel does as well. But one of the spaces where I see this as being especially beneficial is in the mobile space for phones and the like. The reason is simple, there is usually no math coprocessor like their x86 counterparts, and while most software doesn’t use it, others, like say speech recognition and image processing could get a huge boost out of it, and at a modest power cost.
What would be awesome is if Qualcomm published some sort of GPGPU language or spec to the Android foundation, and that made it’s way into the Android framework. Then when the GPU wasn’t being used, or when it was being used lightly, it could be used by code in the way one would spawn a thread to be run, but instead of running in the main CPU it could be run in the GPU, and free up the CPU to spend time doing something else.
I’m sure this has already been thought of and discussed by the Android brain trust, but it just occurred to me, and it would be 100% awesome if it made it into the framework.
