HSA details heterogeneous X86/ARM SoC core plans

SAN JOSE, Calif. — Engineers got their first public look at work-in-progress on an open specification for programming processors using a variety of different kinds of cores. The Heterogeneous Systems Architecture Foundation (HSA) gave a half-day tutorial at the Hot Chips conference here on a set of specs it aims to release in mid-2014.The HSA specs initially aim to let graphics cores act as equal citizens on an SoC with host processor cores, sharing features such as a common pool of coherent memory. They will evolve to include other kinds of cores such as DSPs, codecs, DMA engines, and other accelerators in the future.Advanced Micro Devices led the formation of HSA, whose members now include Imagination Technologies, ARM, and a number of ARM's licensees such as Marvell, Mediatek, Qualcomm, Samsung, and Texas Instruments. The group's goal is to create a standard that informs both the way chip vendors make their SoCs and how software engineers program them.At Hot Chips, HSA members described their current work defining a virtual instruction set architecture that's agnostic to any vendor's ISA and optimized for parallel programming. They also described work on memory and queuing models that seek to be compatible with evolving work on C++, Java, and Microsoft's .Net. The group did not describe its specifications for runtime software or tools, which are still in an early stage of development.To read more, go to “Group Describes Specs for x86, ARM SoCs.”
