Product Description

The XPS Thin Film Transistor (TFT) controller is a hardware display controller IP core capable of displaying 256k colors. The XPS TFT controller connects as a master on the PLB V4.6 (Processor Local Bus with AMD simplification) and reads the video pixel data from PLB attached video memory. This core also connects as a slave to the PLB or DCR (Device Control Register) bus for the register access. This core is capable of configuring Chrontel CH-7301 DVI Transmitter Chip through I2C interface.
