Description

The Heterogeneous System Architecture (HSA) builds on the close physical integration of accelerators and defines a standard for uniting the accelerators architecturally. The HSA specifications include requirements for virtual memory, memory coherency, architected dispatch mechanisms, and power-efficient signals.
HSA aims to bring the benefits of these kernel agents to mainstream programming languages using similar or identical syntax to that which is provided for programming multi-core CPUs.
