LynxExp Embedded Graphics Processor
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 color 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 color 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.
