Video: Silicon Motion SM 750 Dual Display Graphics Chip

Tuesday, February 10, 2015

The Silicon Motion SM750 Dual Display Graphics Chip is a PCI Express 2D multimedia mobile display controller device providing video and 2D capability to the embedded industry in a 265-pin BGA package. 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). Additional GPIO bits can be used to interface to external devices as well. The SM750 is available in 16MB C-Temp and 16MB I-Temp.

The SM750’s 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.
