Low-power display controller core is based on latest ARM security technology

Silicon IP provider Evatronix has released the first member of its Panta high performance display controller core family. Developed using ARM technology the Panta DP20 is targeted specifically at high-end mobile/portable products, like smartphones and tablet PCs, with ultra-low power consumption that does not sacrifice processing performance.

Evatronix Panta is a family of high-resolution display controller and processor IP cores for advanced multimedia applications. Developed as a result of a strategic partnership with ARM, these cores feature the latest technologies available for mobile devices, thus enabling creation of revolutionary applications and greatly enhanced user experience.

The Panta DP20 offloads the general purpose central processing units (CPUs) from power-consuming video processing tasks, like composition of up to 3 graphics or video layers, YUV to RGB conversion, alpha-blending and gamma correction. It supports a variety of display standards and features programmable resolutions of up to 8191×8191 pixels. The processor’s output pixel interface, with HSYNC, VSYNC and blanking signals, is compatible with HDMI (also 3D) and MIPI DPI interfaces. A plethora of RGB and YUV pixel formats are supported, as well as progressive/interlaced video input.

The processor features support the advanced AMBA 4 AXI4 system bus protocol, which increases performance and lowers data transfer latency within the application. As the same bus is supported by the latest ARM Cortex processors and Mali graphics processing units (GPUs), the integration of the Panta DP20 into the ARM environment is made straightforward.

The Panta DP20 is the world’s only licensable display controller IP to currently support ARM TrustZone technology. Access to the Panta DP20 can be controlled by secure signals exported from an ARM TrustZone enabled processor and are able to prevent unauthorised transformations or capture of secured images.
