hi,

one of projects we have done here is video platform for gambling. It has next final specifications:

MCU: SiLabs C8051F120 (128kb program flash, 8kb XRAM, upto 100MIPS)

Memory:
- 2Mb of main purpose memory;
- 2Mb of video memory;
- 8Mb of dataflash memory (via SPI);
- MMC slot for cards;
- 32kb of NV memory (Ramtron FRAM) via I2C bus;

Video:
- VGA 640x480;
- two video layers: background and foreground with transparency;
- two playfields at each layer;
- palette: 256 independent colours for each layer; each colour is translated to truecolour 24-bit RGB via programmable LUTs;
- alpha channel (bright control) for each layer;

DMA:
- one channel upto 53Mb/s transfer rate;
- FIFO implemented;
- four modes of both source and destinator: off/MCU/main_memory/video_memory.
Sound: two channels via 12-bit DACs; 2+2 Watt output;

RTC;
RS-232;
RS-485;
1-Wire isolated interface;

24 input isolated lines;
24 output isolated lines with high-voltage open drain.

Here is the image:


This is commercial project and so I must not provide schematic and firmware; nevertheless if somebody are interested then I can provide ideas and suggestions how-to-do.

Regards,
Oleg
