What is HSA?
Here is one source:
https://en.wikipedia.org/wiki/Heterogeneous_computingHeterogeneous computing refers to systems that use more than one kind of processor. These are systems that gain performance not just by adding the same type of processors, but by adding dissimilar processors, usually incorporating specialized processing capabilities to handle particular tasks.[1]

HSA Foundation And AMD Hit 1.0 Release Milestone For Efficient Heterogeneous System Architecture
HSA is not only destined to impact high-performance computing (HPC) and desktop platforms — as one would expect — it will also impact mobile devices including smartphones, tablets, and notebooks. HSA will make it easier for programmers to “efficiently apply the hardware resources in today’s complex systems-on-chip (SOCs),” including tapping directly into the GPU.

There is no proof offered to make the argument. We already have systems that employ more that one device with computational ability somewhere under the hood. They are given different names, but in fact they are micro-processors of some form. Just not all on one silicon slice.
HDD Controller.
USB controllers
Keyboard Controller.
Graphics processor.
Wireless Router.
Network Controller.
Any of the above can be merged into one chip, if there was an economic need to do so. Some of the new Intel chips have the graphics on the same die as the quad core CPU array. But they don't call it "HSA".
