Crellon Microsystems has introduced a single-slot, 6U VME interface board, with up to two MIL-STD-1553 channels and a PowerPC CPU.

Crellon Microsystems has introduced a single-slot, 6U VME interface board, with up to two MIL-STD-1553 channels and a PowerPC CPU.

The board targets simulation applications requiring very fast data transfers between the host and the interface.

The 1553 channels enable 100% concurrent and independent operation as a bus controller, multiple remote terminals, or as a dual function bus monitor.

The SBS Technologies ABI-V7 delivers a complete 1553 interface for VMEbus systems, including 1553-A and 1553-B selections, programmable bus controller frame lists, bus controller scheduling capabilities, remote terminal response tables, pointer driven transmit and receive buffers, map monitoring, 100% independent sequential bus monitoring and extensive programmable event interrupts.

Up to 56Mbyte of memory is provided for user data structures, and eight external trigger signals are available from the front panel or from the VME P2 connector.

The board provides powerful capabilities for definition of events, to be used as conditions for generating external triggers, or start/stop commands for lists, RT simulations, sequential monitoring and other routines.

An Event can also be used to generate VMEbus interrupts.

The combination of PowerPC processor and VxWorks operating system enables the ABI-V7 to run the entire user application program on-board with little or no host interaction required.

Up to 61Mbyte of memory is provided for user applications running on the board.

The board is backward compatible with the SBS ABI-V5 product, and applications based on this model can easily be ported to run on the ABI-V7.

Software support for the ABI-V7 includes host processor device drivers to the control and data structures, as well as an application layer to these structures.

Low level drivers for most operating systems are also included at no extra cost.

An integrated avionics library, including source code, developed by SBS Technologies, is also available with the board at no additional cost.
