DSP-Board D.Module2.DM642
nicht für Neuentwicklungen - als Alternative empfehlen wir das D.Module2.C6657
Das D.Module2.DM642 basiert auf dem Texas Instruments DaVinci Prozessor TMS320DM642. DaVinci-DSPs sind speziell für die Video- und Bildverarbeitung optimiert.
Key Features
- TMS320DM642 fixed point Signalprozessor
- 100MBit Ethernet, USB 2.0
- 64 Mbytes RAM
- 3 schnelle parallele Video Schnittstellen
- 2xUART, I2C, GPIO
- eigenständiger Betrieb ohne PC
Anwendungen
Das D.Module2.DM642 eignet sich hervorragend für die industrielle Bildverarbeitung, von optischen Kontrollsystemen über Sortieranlagen und Robotik bis zur biometrischen Zugangskontrolle. Spezielle Videoports vereinfachen das Kamera-Interface und das Einlesen vorverarbeiteter Bilddaten aus einem FPGA.
Eine Ethernet-Schnittstelle ermöglicht Fernwartung, Fernsteuerung und die Integration in die Produktions-Infrastruktur.
