ORGFX- a Wishbone compatible Graphics Accelerator for the OpenRISC processor Per Lenander

Modern embedded systems such as cellphones or medical instrumentation use increasingly complex graph-ical interfaces. Currently there are no widely used open hardware solutions to accelerate embedded graphical applications. This thesis presents the ORSoC graphics accelerator (ORGFX), an open hardware graphics ac-celerator that can be used with programmable hardware. A standalone software implementation is provided to help for a quick development of accelerated applications. The accelerator is able to render 2D, 3D and vector graphics. The example implementation of the ORGFX is integrated with the OpenRISC Reference Platform System on Chip version 2 (ORPSoCv2). The final implementation runs on a Xilinx FPGA at 50 MHz, and provides accelerated graphics output from an HDMI port. An extensive software driver and a set of utilities to ease development for the graphics accelerator are provided along with the hardware. The software implementation of the accelerator uses the same API as the hardware drivers, making it possible to quickly develop applications for the accelerator without access to a physical platform. The final implementation trades performance against platform independence and generality. The com-ponent can be integrated with any CPU or memory chip and works alongside a custom display core tha
