Features

1.2D Vector graphics accelerator

GV300 core is a 2D graphics accelerator IP core having 2D vector graphics rendering function complying to the OpenVG 1.1 standards.

2.Small scale and low power consumption core

The graphics architecture of GSHARK-TAKUMI is carried over, and design methodologies have been used to achieve a low gate counts, a small area in SOC, and low power consumption thereby achieving both high drawing performance and low power consumption, and hence making this ideally suitable for mobile equipment such as mobile phones.

3.Realizes high performance 2D vector graphics due to hardware

Curved line division processing, etc., are processed in a flexible manner by TAKUMI's original vertex processor. It reduces the burden of typical 2D vector processing on the CPU, thereby realizing high performance vector graphics in embedded systems.

4.Conforms to industry standard specifications

By conforming to the OpenVG standard API established by the Khronos Group, there is high affinity with PC applications. In addition, there is high affinity with middleware and development environment, etc.. It reduces the application development cost of the customers.

5.Easy system level integration

The data of the core is provided as a synthesizable RTL,so that the customers can integrate it without depending on the process of the ASIC. Also the RTL connecting with the customer's circuit can be modified by customers easily, therefore it is possible to customize and tune the interface section to suit the customer's design. For example, it is easy to integrate to SOC of the customer from a standard bus system such as AXI to an original bus system of the customer.

Deliverables

OpenVG 1.1 Library

Applications

Mobile phones, portable AV equipment, digital AV equipment such as TV or STB, etc.
