10 Aspects Hardware Performance Development Software

11 Hardware Aspects Feature PC DSP Remark Power Consumption Heatsink/Fan L J Example: VisionCam XS 3 Watt; VisionBox AGE 10 Watt; VisionBox AGE-X: 25 Watt SoC System on Chip K J The PC still needs a chipset Multi Core Processor J J Available for both technologies Long term availability K J Embedded line of Intel processors DSP are available for more years On board frame grabber like camera link K J Standard for DSP VisionBoxes Copy of the embedded solution L J Together with OEM definition of a hidden hardware is more easier with a DSP Access to basic interfaces L J PC is more complex on the side of driver Access to market interfaces, USB, PCIe J L OEM hardware extension K J Development of customer specific interfaces is easier. Compactness of the overall system K J Costs J J Make a complete calculation inclusive all involved engineers; support; risk.

12 Performance Aspects Feature PC DSP Remark Overall application performance J K Very general! Depends on the application, competence of programmers. Methods of code optimization K K Both platforms are not easy, without work no success. Optimized libraries J K You find more PC optimized libraries in the market. Determinism K J Very good for the DSP supported by the development tools Manipulation of the data flow K J Bandwith is an aspect of performance of the complete system and not only memory. General benchmarks L L The true benchmark is YOUR application. Application installation K J PC installation routine; DSP one file

13 Development Aspects Feature PC DSP Remark Development Tools J J Using C++ Code J K Some restrictrions for the DSP. However Halcon has been compiled. Costs of development tools K L Debugging on the target platform J J A question of comfort. Some advantages for both ways. Speed of software innovations J K Focus on the application K J More freedom on the PC is a risk because a lot of things can be installed / tested. Interface development K J Is more hamonized for the DSP incl. C-API, could cause risk for the PC, e.g. USB Support K J DSP one contact; PC - a lot of responsabilities, error ping pong Additional tools from the market J L Driver K J More risks on the PC side, updates, error risk. Side effects can cause problems GUI programming J K More easier for the PC.

14 Software Aspects Feature PC DSP Remark Availability of a lot of additional software J L Protection of your intellectual property K J IP is a combination of your software and the hardware it runs on. Management of virus software / risk L J Database access J L FTP; TCP/IP network access J J DSP platform can fully integrated into the IT network Setup of a system with touch interface J J Backup, amount of data, simplicity K J Windows OS J L Compatibility between HW platforms J J Integration of camera driver J K Camera driver are a part from the camera vendor. Familiar to use the device J K DSP system easy to use because of less functions which the user can manipulate.

15 Interleaved functions of your vision system Firmware + Hardware Real Time OS DSP/BIOS or Win7e IMAGO C++ Interface Example Program C++ Library Your Library HALCON TI Open CV Your Application

16 Summary IMAGO Offers embedded cameras & computer based on Texas Instruments or Intel processors DSP or ATOM? There is no clear winner because the user, market and application requirements are too different. Our recommendation: Try to define your goals & priorities inclusive the vision competence of your company. Start a trustful & deep discussion with the IMAGO experts to decide the future of your machine vision system.
