The USB board provides centralized communication between the image sensor and the
host PC. The system receives firmware programming from a serial EEPROM that config-
ures the board into a synchronous slave FIFO mode. The sensor data fills up an internal
FIFO with data when the elimination of handshake is taking place. The firmware auto-
matically sends data through the USB 2.0 interface whenever the FIFO becomes full and
the FRAME_VALID is polled to determine when a frame is complete. When the
FRAME_VALID drops, the host computer is signaled through the USB interface with a
frame end packet. The firmware also supplies the necessary code to implement USB
vendor commands that allow the host computer to query and modify the system config-
uration data.
Vendor commands are used to communicate with the image sensor through the serial
host interface protocol built into the sensor head interface.
Micron’s DEMO2 board comes equipped with the addition of an FPGA and memory
controller. This allows the hardware to store up to three entire frames of data on the
board prior to USB 2 transport, which is important for large resolution sensors to avoid
dropping frames. The DEMO2 baseboards are common to all sensor configurations. The
FPGA optimizes the data flow through the USB, such that the FIFOs never overflow and
complete frames are guaranteed even for large sensors.
