-
with push towards multimedia enabled mobile devices seems logical way boost performance on these platforms, while keeping general purpose software power efficient. i've been interested in ipad hardware developement platform ui , data display / entry usage. curious of how processing capability device capable of. opencl make juicy hardware platform develop on, though licensing seems kinda stinks. opencl not yet part of ios. however, newer iphones, ipod touches, , ipad have gpus support opengl es 2.0. 2.0 lets create own programmable shaders run on gpu, let high-performance parallel calculations. while not elegant opencl, might able solve many of same problems. additionally, ios 4.0 brought accelerate framework gives access many common vector-based operations high-performance computing on cpu. see session 202 - accelerate framework iphone os in wwdc 2010 videos more on this.
