Heterogeneous processing represents the future of computing, promising to unlock the performance and power efficiency of the parallel computing engines found in most modern electronic devices. This talk will detail the HSA computing platform infrastructure including features/advantages across computing platforms from mobile and tablets to desktops to HPC and servers. The talk will focus on technical issues mapping DSPs to HSA systems using GPT's new DSP processor as a representative example. The presentation will also discuss important new developments that are bringing the industry closer to broad adoption of heterogeneous computing.
