CommIO-IP Ariel IndustryPack VME Carrier Module

CommIO-IP is a single-processor TMS320C40 board for flexible, modular I/O in VMEbus systems. CommIO-IP can be used as a self-contained I/O and DSP system or as an I/O subsystem for use with DSP boards based on the Texas Instruments TMS320C4x processor family. I/O functionality is provided by up to four IndustryPack modules fitted to the CommIO carrier; two of the IP sites are connected to each of the C40's memory buses for maximum I/O throughput. A VMEbus slave interface via a bank of dual-port SRAM supports software development and debugging as well as I/O for external VMEbus master boards. When used as an I/O subsystem, the CommIO-IP card communicates with one or more external C4x processors via the C40's high-speed parallel communication ports; four comm ports are available on front-panel connectors that are compatible with standard Ariel cables (not included). I/O connections to the IndustryPack module are available via on-board 100-pin connectors and may be brought out to the front panel by means of connector transition modules (ordered separately). CommIO is a 6U VME board which includes a 50 MHz TMS320C40 processor (running at 48 MHz for optimum synchronization with the 8 MHz IP bus), a bank of zero wait-state SRAM on each memory bus of the C40, a 128K x 8-bit bank of flash memory, a JTAG interface header, and an on-board JTAG test bus controller to support use of Ariel's AXDS-series debuggers. CommIO-IP is sold without IndustryPacks, connector transition modules, documentation, or software.
