PRO154 DELPHIN Version: V1.0, December 1985 Submitted by: R. J. Wilden, Philips GmbH Forschungslab.Aachen, Postfach 1980, West-Germany 51 Aachen Operating System: P/OS V2.0A Source Language: FORTRAN 77, MACRO-11 Memory Required: .512MB Software Required: PRO/Tool Kit, PRTIL Hardware Required: PRTI, DELPHIN-300 Keywords: Utilities - P/OS Abstract: This package contains three tasks, controlling special low cost process-I/O hardware (DELPHIN-300 System) connected to the PRO's RTI (Real-Time Interface). DELTS1 is a menu driven test program for the DELPHIN-Hardware using the PRTIL-Calls. The connections between the PRO's PRTI and the DELPHIN I/O System is shown in the GIDIS-Metafile DELCON.GID. Use the PRO/Sight frame viewer or the print service with an LA50 to display the picture. The other two tasks DELMCO and DELMEM are parts of a multitasking application. In this case, the PRTIL is not used, but the I/O is done using the device registers of the PRTI in the I/O-Page directly. Task DELMEM is a macro task which performs the actual I/O. The other task used (DELMCO) calls the function from DELMEM via subroutines. These subroutines send and receive messages to and from task DELMEM. To map the I/O-Page task DELMEM is a privileged task. With the multitasking application, you can use the DELPHIN-300 system's data acquisition facility with the speed of the ADC used (ca.12KHz). Higher speeds are possible (it depends on the ADC's conversion time). To solve the problems with the PDP's lack of virtual address space, MMU-directives are used. The measured data can be saved on an RX50 diskette with logical I/O. Read the comments in the source files for information about the functions implemented.
