The logi3D 3D Graphics Accelerator IP Core - Future Performance Improvements

The logiGPU Graphics Demonstration Kit emulates future implementations of the logi3D Scalable 3D Graphics Accelerator IP core on the Xilinx® Zynq™-7000 EPP. The logi3D IP core implementation in the Xilinx Zynq-7000 EPP will be a big leap ahead in performance compared to the logiGPU Graphics Demonstration Kit.

The following table summarizes Zynq-7000 features which will enable better logi3D performance:
 
logiGPU 3D graphics performances vs. Xilinx Zynq-7000 3D graphics performances
     * Xilinx Automotive Grade Zynq-7000 2x ARM Cortex-A9 targeted to 667MHz max

Up to 3000 interconnects between the processing system and programmable logic in the Zynq-7000 EPP will provide much higher data throughput than the current interface (GPMC) between the ARM processor and the logi3D implemented on the Xilinx Spartan-6 FPGA in the logiGPU kit. Together with the faster system clock and improved processor cores, i.e. ARM Cortex-A9 running at 800MHz vs. ARM Cortex-A8 running at 600 MHz, these Zynq-7000 features will improve the overall logi3D 3D graphics performance.

In addition to that, designers of Zynq-7000 EPP SoCs may decide to dedicate one ARM Cortex-A9 processor core to 3D graphics and isolate low-level logi3D functions from the user application.

The Zynq-7000 family’s programmable logic is based on Xilinx’s newest 7 series FPGA architecture and provides higher performance than the Xilinx Spartan-6 programmable logic. The logi3D IP core runs at 80 MHz in the Spartan-6 FPGA and is expected to run faster in the Zynq-7000 programmable logic and increase the graphics performance - CLICK HERE to check the logi3D datasheet.

Product is based on a published Khronos specification, and is expected to pass the Khronos Conformance Testing Process. Current conformance status can be found at www.khronos.org/conformance.
