.@HSAFOUNDATION releases version 1.1 of its SoC spec, defines IP block interfaces
SAN JOSE, Calif.—The Heterogeneous System Architecture (HSA ) Foundation defined interfaces for third-party IP blocks so engineers can design SoCs compliant with its specs for shared coherent memory. To date, only Advanced Micro Devices, which initiated the group, ships a processor supporting the ad hoc standard for speeding up on-chip processes shared among different cores. The HSA spec is positioned as a more open alternative to the SoC techniques and programming environments supported by Intel and Nvidia. The interfaces defined in HSA’s version 1.1 released today are already baked into a handful of CPU, GPU, DSP and fabric cores from at least three vendors including Arteris and Imagination Technologies. “In our version 1.0, SoC makers didn’t need to define how, say, a DSP gets access to a shared memory-page table,” said John Glossner, HSA’s president. “Now what were opa...
