The EPM supports a number of different cameras and image sensor boards. Mobileye is currently supporting the following images:
- Micron MT9V023/MT9V024 CMOS sensor based camera module, RCC version.
- Micron MT9V023 CMOS sensor based camera module, BW version.
The typical Horizontal Field of View (FoV) for capturing video images is 40º. The EPM can be run in two modes: stand-alone and PC HOST-controlled, with the EPM accepting video packets downloaded over a USB2 bus from an external PC via the SIM.
The basic EPM platform includes:
- EPM + SIM development boards.
- LVDS or parallel Camera module.
- Power supplies.
The EPM can include the optional analogue to digital (A2D) board to support analog cameras. The offline system includes: PC notebook with CAN interface Mobileye EyeQ® Client application (incorporates Mobileye Off-line application) SIM Board Optional CAN card and cables The EPM can also be expanded as a software development platform for the Mobileye EyeQ®. A board support package (SW) enables customers to port their own code onto the ARM processors. Probe, Compiler and debug tools for ARM are not included and should be purchased from third party (e.g. Green Hills).

SIM – Serial Interface Module Specifications
The SIM needs to supply the connectivity between the EPM and the development environment running on a Host PC so that EPM+SIM+PC together offer an application development platform.
2. Functional characteristics
The SIM, with the EPM being mounted on top, offers “Cigarette size” module with the following application development capabilities:
– USB-2 peripheral for the Host PC
– Bi-directional Digital Video transport (USB2) for download or upload of Video data to Host PC
– Receiving the video data stream from the EPM’s two attached cameras and also from the EyeQ real-time
processed Video data port ( DISP-OUT port ) and preparing them ( Time-Stamping using FPGA logic ) for
upload to Host PC for storage or Display
– Downloading of two Video data streams from Host PC and transferring them to EPM’s EyeQ Video inputs
after reformatting to a Camera raw data format

Mobileye EyeQClient Application & On-line/Off-Line system
The EPM unit is designed to function as a standalone module for running Mobileye’s applications during the development phase. However, there is a need for higher level controlling abilities of the EPM, such as: On-line view, software upload, calibration, data logging, recorded data review and rerun of recorded data on the EyeQ®processor in Off-line mode. All these abilities are provided in the Mobileye EyeQ® client application.
The SIM board serves as an interface between the EPM and the PC that serves as the computing platform for the client application via the USB2. The Mobileye EyeQClient supports direct CAN interface with the EPM board.
Mobileye’s EyeQ® client application runs on an IBM notebook computer and provides a convenient interface application to the EPM board and to the Mobileye applications. The application includes a menu based user interface and a video display window. Hardware description:
– IBM Notebook computer with USB2.0 interface running Windows XP OS
– SIM board for the USB 2.0 high-speed interface
– Dual CAN-2.0A/B using PCMCIA card plus two CAN cables (connections to the EPM and to the vehicle CAN
bus). Supported cards: Vector CANcardXL & KVASER CAN card
The client application provides the following functionalities:
– On-line viewing of the image processing results – Video display of the image sequences and the
application results (e.g. targets, lanes, features)
– User data input – for calibration, selecting run modes, and setting of parameter values
– Downloading software updates to the EPM
– Data logger: Recording of video and vehicle CAN data
– Launcher: Allows re-computing recorded video sequences on the EyeQ chip. (For benchmarking –
re-running the application on identical video sequences using different versions of the application and/or
different parameters or running options)
– Player: Allows viewing the results of previously computed video sequences.
