The formation of the Heterogeneous Systems Architecture group by AMD and friends and AMD's announcement of its licensing of an ARM core looks like a good start to a neuromorphic era.
In April 2011 I was already arguing that AMD would eventually have to license ARM processor cores. And at the AMD Fusion developers conference in June 2011 Phil Rogers, AMD Fellow, said that Fusion processors the ones that include CPU and GPU cores would become CPU and GPU agnostic.
AMD as the mirror image of Intel two hombres facing each other down main street with x86 six-guns to hand is so entrenched in the semiconductor industry that many people couldn't quite get their heads around what Rogers was saying last year.
It didnt seem to make many people go "woah you mean processors from AMD with ARM cores inside?" But AMD has followed up at this year's Fusion developer summit with the announcement of the formation of the Heterogeneous System Architecture (HSA) group, with some interesting founder members and some notable absentees.
It is farsighted stuff and in my view the research people at AMD are rightly viewing systems from the top down and as they will be seen in three or four years' time, with hundreds and thousands of processing elements (PEs).
In other words CPU and GPU cores and other PEs are the new gates. There will be layers of software above we hope to provide a tractable programming model. It is the HSA group's job to make/allow that to happen.
In short, we are entering an era where programmable systems will be much closer to models of the parallel processing of the brain than to the 5F1 circuit for a Fender guitar amplifier. We are entering a neuromorphic era and leaving behind a circuit-oriented era.
It will be interesting to see whether the likes of Intel, Nvidia, Qualcomm, Xilinx and Altera can share this vision. Even if some of them DO share the vision, commercial competitiveness may persuade them NOT to join HSA on the grounds that differentiation is achieved by working separately or in a different group. Market pressures sometimes do that to technology.
