AMD’s heterogeneous system architecture (HSA) initiative has been a steady interest since the company first started talking about “Fusion” processors in 2007. Today, at the international Hot Chips computing technology conference, the company gave a talk that laid out details behind what its HSA Foundation has designed and the language that powers the technology, dubbed HSAIL (HSA Intermediate Language).

It’s best to start with a basic overview of the problem. Despite the popularity of OpenCL and Nvidia’s direct investment of hundreds of millions of dollars into its Tesla products and CUDA software, the actual task of moving work from CPU to GPU, performing it, and bringing it back again is still a giant headache. The simplest explanation for the problem is this: For most of history, the trend in computing was to move tasks to the Central Processing Unit, which would then perform them. Gaming is virtually the only workload that has resisted this tendency (moving a GPU on-die is not the same thing as programming a game to run on the CPU).
