This may offer hope for future controllers for diy LCD projectors. It only displays upto 1024x768 but that is enough for 720p
AMD Alchemy™ Au1200™ Processor
The AMD Alchemy Au1200 processor gives system designers an easy-to-use, simple solution to create full-featured PMPs with greatly reduced design cycle times. System-on-Chip (SoC) architecture eliminates the need for additional components.
Transcoding not required
The Au1200 processor supports common digital video media, including MPEG, DivX, and WMV9, and delivers full D1 resolution without the need to transcode content between PC or PVR and the PMP. This reduces the time required to download fresh content and helps enable consumers to take media “on the go” faster and easier.
The Au1200 processor also leverages a unique approach to DDR1 and DDR2 memory to deliver better overall performance than SDRAM components. And the Au1200 processor achieves faster I/O via USB 2.0 to give designers a range of enhanced connectivity options.
No need for DSPs
The AMD Alchemy Au1200 processor incorporates an integrated Media Acceleration Engine optimized for video to eliminate the need for DSPs and specialized coding. This means less overall power consumption and a simplified design.
LCD controller design optimizes displays
The AMD Alchemy Au1200 processor features an LCD controller that gives developers full 32-bit RGB capabilities in each of four prioritized overlay windows that require no frame buffer modifications to reposition. The processor also features gamma correction for matching video displays with graphics, a global background color that simplifies processing and produces an aesthetically pleasing display, and a 1KB palette RAM frame buffer that is ideal for displaying information in portable device idle modes.
