Abstract:

This report presents the implementation of a software interface between a Unix operating system executing on a Navy DTC-2 VMEbus computer workstation and a VMEbus ANUYK-44V enhanced processor EP embedded within that workstation. The interface software employs the Unix STREAMS mechanism to emulate the ANUYK-44V inputoutput controller IOC function. Emulated capabilities include IOC page register groups, multiple inputoutput controllers, input, output, external function, and forced external function transfers, and external interrupt. The ANUYK-44V application directs the interface by supplying ANUYK-44V command instructions and chain programs in memory. The Unix application communicates with the interface using the Unix file system calls.
