Vivante Corporation is a fabless semiconductor company headquartered in Sunnyvale, California, with an R&D center in Shanghai, China. The company was founded in 2004 as GiQuila and focused on the portable gaming market. The company's first product was a DirectX-compatible graphics processing unit (GPU) capable of playing PC games. In 2007, GiQuila changed its name to Vivante and changed the direction of the company to focus on the design and licensing of embedded graphics processing unit designs. The company is licensing its Mobile Visual Reality to semiconductor solution providers that serve embedded computing markets for mobile gaming, high-definition home entertainment, image processing, and automotive display and entertainment.

Vivante is named as a contributor to the HSA (Heterogeneous System Architecture) Foundation.[1]

In 2015, VeriSilicon Holdings Co., Ltd. to acquire Vivante Corporation in All-Stock Transaction.[2]

Products[edit]

Since changing directions Vivante has developed a range of GPU cores that are compliant with the OpenGL ES 1.1 and 2.0 standards as well as the OpenVG standard. Created by VeriSilicon support for the Vulkan API 1.0 and for OpenVX 1.0 is provided for at least 6 major desktop and embedded operating systems.[3]

2D graphics products & Vector GPUs, summarized by the vendor under the term "Composition Processing Cores" (CPC),[4] sometimes mentioned with the feature of single pass composition blending capability of 8 or higher, are the GC300,[5] GC320, GC350[6] and GP355 (OpenVG core[7])with the additional listing of GC200 and GC420.[8] NXP further mentiones GC255 in a presentation for their i.MX models.[9] Recent leak-alike publications show that the NXP i.MX8 series might come with 1 or 2 units of the GC7000VX vector processor, that seemingly has 8 shader cores per unit in order to support OpenVX.[10] For 3D graphics products please see the table below.

Adoption[edit]

They have announced that as of 2009 they have at least fifteen licensees who have used their GPUs in twenty embedded designs.[32] Application processors using Vivante GPU technology:

Linux support[edit]

There are no plans on writing a new DRM/KMS driver kernel driver for the Vivante hardware, since Vivante previously put out their Linux kernel component under the GNU General Public License (GPL), instead of maintaining it as a proprietary blob. The free Gallium3D-style device driver etna_viv has surpassed Vivante's own proprietary user-space driver in some benchmarks.[citation needed] It supports Vivante's product line of GC400 Series, GC800 Series, GC1000 Series, GC2000 Series and GC4000 Series.[39]
