HSA spec upgrade supports multivendor SoCs

The Heterogeneous Systems Architecture (HSA) Foundation - a grouping of chip, IP and software companies - has released the HSA 1.1 specification claiming it takes developers closer to energy-efficient heterogeneous computing.

By Peter Clarke, EETimes, May. 31, 2016 – 

The specification update comes just over a year after v1.0 and enhances the ability to integrate proprietary IP blocks and blocks from multiple vendors in heterogeneous designs

The specification is intended to allow developers to write software and efficiently apply it to hardware resources of multiple types - CPUs, GPUs, DSPs, FPGAs, fabrics and fixed-function accelerators. This can be done by writing in OpenCL 2.X, C++, Java and compiling to HSAIL, the HSA intermediate language.

The additions under HSA 1.1 include: multi-vendor support, improved interoperation with graphics, cameras and other image processors, digital signal processors; a formal definition of the HSA memory model; support for system-level profiling; run-time improvements including the capability to wait on multiple signals, a non-temporal memory access that allows infrequently used values to be removed from a cache efficiently
