Imagination GPU Joins SiFive RISC-V Design Ecosystem

There are not a lot of other options for GPU IP that is not tied to a specific vendor

eetasia.com, May. 21, 2019 – 

SiFive has added Imagination Technologies' PowerVR GPU and neural network accelerator (NNA) IP cores to its design platform, making it the first fully-featured GPU IP to be available in its design ecosystem for developing RISC-V based chips.

Speaking to EE Times at the company's RISC-V tech symposium in Cambridge, Krste Asanovic, co-founder and chief architect of SiFive, said, "There are a diminishing number of suppliers in the GPU space, and we are very pleased that Imagination wants to work with us on that. There are other GPUs out there, but they are tied to a specific vendor and not available as IP. So if you wanted to go build a RISC-V based SoC that had a GPU on it, there were pretty limited choices up until now. I think this will open it up for our customers who need a GPU."

The PowerVR GPU will be available via the Vulkan applications programming interface (API) in SiFive's DesignShare ecosystem; the latter features pre-integrated IP from multiple vendors to ease prototyping of systems-on-a-chip SoCs without having to pay upfront license fees.

Imagination's PowerVR Series8XE GPU and PowerVR Series3NX NNA IP will be available for customers to use in their DesignShare SoCs, with the expectation of further Imagination IP being made available in the future to meet market demand. The PowerVR software has been designed to work with all processor architectures, including the rapidly growing, open standard RISC-V that is at the heart of the SiFive DesignShare ecosystem.
