Multicore silicon GPU exceeds 1GHz

Vivante Corp. announced that licensees of its GC series architecture have exceeded 1GHz in clock frequencies. The GPUs target next-gen game consoles, tablets, smartphones, automotive displays and home entertainment apps.

Vivante's multicore GPUs are extensions of the single-core GC series architecture launched in 2007. The multicore GPUs are capable of delivering performance of more than 200-million triangles per second on polygon throughput feature tests, the company said.

Examples from the GC family have been licensed to more than 40 companies and ranges from the GC400 and GC800 single core GPUs, to the multicore GC1000 to GC4000. The company announced it had signed its 15th GPU licensee in June 2009. Vivante added that the multicore GPUs offer up to 10 times higher performance than the GC800 single core GPU. Multicore GPUs are available in configurations with up to 64 compute elements in 2 to 8 pipelines.

Vivante also licenses the GC350 fixed function OpenVG 1.1 compliant GPU, as well as the GC300 programmable GPU engine.

Vivante's multicore GC-series has driver support for a range of graphics APIs including Khronos Group conformant OpenGL ES 2.0/1.1, OpenVG 1.1, OpenGL 3.0/2.1, as well as Microsoft certified DirectX 11 feature level 9.3, Direct2D and DirectFB 1.4. Vivante GPUs are also designed to offer support for the OpenCL 1.1 embedded profile for general purpose computing on the GPU.

"Our multicore GPUs deliver the ultimate graphics performance well within the typical power budget of a few hundred milliwatts with the GPU running complex applications at maximum speed," said Wei-Jin Dai, president and CEO of Vivante, in a statement.
