F4100 provides a common development platform. The platform consists of the following five parts:
1. F4100 controller board;
2. DMD motherboard, DMD chip, and cable;
3. Upper computer control software F4100 and D4100;
4. Power cable;
5. Experimental power supply, 5V @ 5A type.
The F4100 system provides complete interfaces (USB or extension interfaces), data processing (Virtex 5, DDR), and DMD controllers (DDC4100, DAD2000, DMD) in DLP development and application. The following diagram is a simplified schematic diagram of the F4100 control platform:
Sim4100 the development system includes:：
- 1. Power-on and reset driver for a single DAD2000: Realizing reset control for 16 blocks of the DMD mirror, while supporting higher frequency resets. The single DAD2000 operates in XGA mode;
- 2、DDC4100 digital controller: The FPGA XC5VLX30 chip from Xilinx Company is used to achieve complex control of DMD and DAD2000, providing high-speed 32bit/64bit Low Voltage Differential Signaling (LVDS) data and control user interfaces, all of which come from user FPGAs. Initialization and control of DMD and DAD2000 are implemented based on input signals from user FPGAs. The DDC4100 digital controller is actually an encrypted chip;
- 3、32bit/64bit, 400MHz double data rate (DDR) DDC4100 data interface: 32-bit XGA interface operation;
