PCI Express 2D multimedia mobile display controller

The SM750 is a PCI Express 2D multimedia mobile display controller device, packaged in a 265-pin BGA. Designed to complement needs for the embedded industry, it provides video and 2D capability. To help reduce system costs, it supports a wide variety of I/O, including analog RGB and digital LCD Panel interfaces, two Zoom Video interfaces, and Pulse Width Modulation (PWM). There are additional GPIO bits that can be used to interface to external devices as well.

The 2D engine includes a front-end colour space conversion with 4:1 and 1:8 scaling support. The video engine supports two different video outputs (Dual Monitor), at 8-bit, 16-bit, or 32-bit per pixel and a 3-color hardware cursor per video output. The LCD panel video pipe supports a back-end YUV colour space conversion with 4:1 and 1:212 scaling. A Zoom Video (ZV) port is also included to interface to external circuitry for MPEG decode or TV input.
