Jade
The Jade GDC at the hub of the first IdeaBoxx is Socionext's most cost-effective, SOC-based display controller. Based on an
ARM™ 926EJES processor running at 333MHz, Jade has a fixed-pipeline, 3D graphics engine powerful enough to produce
sharp, crisp graphics on screen sizes up to 1024 x 768. Fabricated in Socionext’s standard 90nm process, this graphics
display controller is designed to provide the optimal balance of power, via low leakage current, and performance. Jade can
support two screens independently, along with dual-capture ports, and can apply video images to 3D meshes via texture
mapping. This combination of features makes Jade ideal for many industrial and medical applications where screen sizes
of 4 to 10 inches are common.
A hierarchical bus system isolates high-performance functions (e.g., 3D graphics processing) from routine operations (e.g.,
low-speed I/O). Socionext has designed the ARM processor to run at twice the rate of the graphics core to reduce memory
bus contention between these two primary functions.
