Display processor IP uses latest ARM security technology

May 09, 2012 // By Nick Flaherty
Polish silicon intellectual property (IP) provider Evatronix has launched the first member of its PANTA high performance display controller core family using the ARM TrustZone security technology.

The PANTA DP20 is targeted specifically at high-end mobile/portable products such as smartphones and tablet PCs with ultra-low power consumption that does not sacrifice processing performance. It 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 unauthorized transformations or capture of secured images.
The DP20 off-loads 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 8191x8191 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 supports the 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 straightforward.
“When ARM security technology is integrated into innovative solutions, such as the Evatronix PANTA DP20, higher levels of protection are possible," said Ben Cade, vice president and general manager, secure services division at ARM. "This makes it easier for consumers to carry out mobile payments, share personal data and view premium content using their smart connected devices.”
