The low cost, low power GC200 Graphics Processing Unit (GPU) IP by Vivante is designed for handheld devices like cell phones, digital cameras, personal printers, digital photo frames, portable navigation devices, portable media players, set-top boxes, televisions and electronic toys. It includes full-featured 2D graphics and HD 1080p imaging, and it delivers higher performance, smaller die size and lower power consumption than existing 2D graphics processors.
Hardware / Software / Ecosystem
An optimized software stack and complete software development tools fuel a growing application ecosystem supported by our robust graphics pipeline. With native support for DirectFB and GDI/DirectDraw, Flash acceleration capability, and Android, Linux, and Windows embedded development environments, Vivante delivers optimal performance for 2D applications.
Silicon Efficiency
Our ScalarMorphicTM architecture and other innovations result in the smallest die size in every GPU class. Vivante solutions are optimized to reduce bandwidth and power, and to minimize the CPU load for real applications. These features are absolutely essential for building efficient embedded systems.
Full-featured high performance, low power, and smallest area mean that Vivante delivers the best in graphics quality at the lowest silicon cost.
Easy to Integrate
With support for free-running AXI/AHB or OCP interfaces, customers can easily integrate our cores into their systems. Vivante licensees quickly and consistently reach target frequency and optimal final silicon area using provided reference implementation kits for Cadence and Synopsys design tool environments
Performance**
250M pixels per second [textured] (65nm LP) to 375M pixels per second [textured] (65nm G+)
** Based on a push-button implementation flow. Higher performance is possible with a custom flow.
