Hardware High Level Design James

Completed Goals HC11 wired up and executing commands via EPROM SRAM written to and verified Latch and Bus drivers wired up Schematics drawn to present stage in design Most parts have been acquired James

uProcessor, Bus Driver, and Latch Maurio

Control Logic, EPROM, and SRAM Maurio

Optics Cell Phone Camera Lens Size and Shape same for our CCD Focal length and lens are perfect Probably has filter to eliminate IR Can be used for testing CCD output Alternate lens idea: Used lens Definitely passes IR radiation Need to figure out focal length for CCD size Maurio

CCD Maurio

Suggested Wiring/Drivers

Input Waveforms Brian

Output Waveforms Max Freq MHz Conforms to RS-170 black and white TV (30frames/sec) Brian

Xilinx VGA module VGA data FPGA Video logic Current Row & Column 8-bit pixel data Interface to RAM VGA logic Brian

Software Processes Three main software programs: Boot monitor Camera operating system Computer interface program Eric

Boot Monitor Stored in ROM First thing that runs when HC11 is reset Provides simple interface via RS-232: Upload new OS software into RAM Run basic tests Inputs: OS software, test commands Outputs: Running software, test results Eric

Camera OS Stored in RAM during development Can be burned into ROM when finished Multiple interfaces: Camera logic Computer Shuffles data around Does not compute anything Eric

OS–Logic interface Interfaces with the FPGA to take a picture and get the image data Inputs: Image Data Outputs: Control signals to disable frame updates Eric

OS-Computer interface Interfaces with PC workstation via custom serial protocol Protocol is very simple Commands processed serially No need for multiple threads or interrupts Inputs: “Take picture” command Outputs: Image data in predefined RAW format Eric

Computer software Provides the UI for the camera Allows user to interact with boot monitor and OS Displays captured images Saves images as JPEG files Eric
