Key Benefits

1. The high performance third generation GSHARK-TAKUMI architecture

GT4 adopts the third generation GSHARK-TAKUMI architecture with significant enhancements on graphics performance and bus efficiency, realizing high performance and low power consumption with higher performance/size ratio. GT4 also comes with the optional high speed module, enabling optimized performance and gate count trade-off.

2. High performance 3D rendering

GT4 implements one of a kind 3D graphics engine to allow high-performing intuitive GUI menu. GT4 accelerates a variety of 3D applications including GUI, 3D map and game.

3. Smaller and less power consuming

Inheriting GSHARK-TAKUMI graphics architecture well-accepted in mobile devices and introducing the design approach targeting the smallest-in-class gate count and power consumption, advanced graphics rendering performance and small power consumption come together to make GT4 an IP of choice for mobile devices including handsets.

4. The hardwired approach for advanced performance and quality graphics

GT4 processes the high-load graphics tasks including transforming, lighting, rasterizing and pixel processing in the hardware to allow high performance and quality graphics even in embedded systems.

5. Conformance

GT4 supports and conforms to the Khronos Group standards, OpenGL ES1.1. Adopting the industrial standard API makes GT4 friendly to PC or smartphone applications and allows use of standard-supporting middlewares and development environments, which will securely reduce the application development time and cost at customer’s end.

6. Easier system integration

GT4 as well as other GSHARK-TAKUMI IP cores is provided in synthesizable data for independence on the semiconductor process technologies. Interface to the customer logic also supports the industrial standards and is provided in a customizable format, allowing easier modification to the customer design asset. For example, GSHARK-TAKUMI is easily integrated to the customer SoC interfacing the standard bus system such as AXI to the customer's original one.
