Vision Cam PS / SM2-D1024-80 3 Hardware Overview



3. Hardware Overview The three main components in the block diagram are the CMOS camera, the FPGA and the digital signal processor (DSP). These components are especially designed to transfer high data rates and to communicate with each other. The used high speed communication protocol is called Sun-System-Protocol (SSP). The CMOS camera module is a camera module of the MV-D1024E-series from Photonfocus, with all its included features like 1024x1024 pixel camera resolution, global shutter, shading correction, LinLog® technology. The image processing computer (FPGA / DSP / SDRAM / Flash) is a processing module based on VisionBox technology from Strampe Systemelektronik. The function of this module is the handling of the image data, the image processing and performing the communication between the components and peripheral devices. The digital signal processor has a fast internal memory of 1024 KB and runs with a maximum frequency of 1000 MHz. There are up to 256 MB external SDRAM, storing image data and program data. The RAM has a maximum data rate of 1 GB/s.

Each VisionCamPS / SM2-D1024-80 features an internal flash memory of 4 MBytes and a µSD card with a default size of 2GB. The internal flash memory is used to store the bootloader, configuration files and the firmware. The µSD card is used to store image data, the executable program and other user data. The communication with external devices is realized with a 1000 Mbit/s Ethernet interface. In this way it is possible to perform high data rates. For other communication purposes, the opto-coupled inputs and outputs, the RS422 transceivers and the serial port are helpful.

Vision Cam PS / SM2-D1024-80 4 System Configuration



4. System Configuration 4.1. Application Development The development of applications is done with the Code Composer Studio (CCS) from Texas Instruments (TI). This development environment runs on a PC and is a full fledged compiler and debugger. A scalable real-time kernel, called DSP/BIOS is integrated with the CCS. This operating system provides preemptive multi-threading and hardware abstraction. Programming is done in C or C++ programming language. Executable files (*.out) and libraries (*.lib) can be created. The essential functions from Photonfocus, Strampe Systemelektronik and TI are summarized in libraries, which are linked to the prepared application. Following the compilation the *.out file can be copied to the µSD card and the VisionCam PS / SM2-D1024-80 is ready to run after power on. It is also possible to copy this program via Ethernet to de µSD card.

VisionBox

A much easier and faster way to develop an application is using a debugging box called emulator. It is a connection from the development PC via USB (alternative: Parallel Port / Card Bus) directly to the DSP in the VisionCam PS / SM2-D1024-80. By pressing one key the application is compiled, transferred to the VisionCam PS / SM2-D1024-80 and ready to run. It is also possible to set breakpoints, watch dogs, edit variables and get a view of the memory used by the application.

4.2. Operation Mode In the operation mode the PC is normally required to setup the camera parameter, for the parameterization of your application or for reporting statistics to a database. The standard user interface is provided by a web browser and a java applet. In this way it is possible to control your application with keyboard or mouse.

It is also possible to create stand alone applications without any PC hardware. In this case the communication is done with a SPC of the inspection system.

Vision Cam PS / SM2-D1024-80 5 Software Development



5. Software Development 5.1. Development Environment The following screen shot shows the development environment Code Composer Studio (CCS) from Texas Instruments (TI). On the left hand side of the screen is the project view window, on the right hand side are the document windows and at the bottom are several debugger windows active.

Before using the Code Composer Studio (CCS), you have to setup the emulator configuration. Start the setup tool and clear the existing configuration. Double click in the available board window on bhemu6400_11 (Blackhawk) or sdgo6400_11 / sdgo6400usb_11 (Spectrum Digital) to change the board properties. With a parallel port emulator, the I/O Port has to be 0x378 with USB 0x0 or 0x510. The processor configuration has to be one TMS320C64xx CPU. No startup GEL file is needed. Power on the VisionCam PS / SM2-D1024-80 and start the CCS. Now it will connect to the DSP.
