This unit
The Concurrent Computer Corporation Real-Time Clock and Interrupt Module (RCIM II) is a PCI-based multifunction card engineered for time-critical applications on Concurrent iHawk multiprocessing systems. It delivers precise timekeeping, interrupt generation, and distributed event synchronization across single and multiple systems - essential for simulation, data acquisition, and industrial control environments running RedHawk Linux.
Technical Specifications Real-Time Clocks
Eight 32-bit programmable POSIX-compliant real-time clocks
64-bit clock resolution with 400 nsec low-order granularity
Minimum resolution: 1 microsecond
Decrementing counters that interrupt on zero crossing
One-shot and periodic operating modes with automatic value reload
Programmable to generate fixed frequencies (e.g., 600 Hz) External Interrupts
Twelve edge-triggered input lines and twelve output lines
Each input independently configurable for edge/level sensitivity and polarity
Input termination: 180 ohms to +5 V; 330 ohms and 0.1 µF to ground
Requires line driver capable of sinking minimum 30 mA
Output signals driven by 74ABT16240 line driver
Runtime control: arm, disarm, enable, disable, and sensitivity selection per line Distributed Interrupts
Twelve distributed interrupt inputs and twelve outputs per RCIM
Enables deterministic event synchronization across multiple iHawk systems
Sources: real-time clocks, external edge-triggered inputs, or software
Chained configuration via synchronization cables for inter-CPU notification
Allows single-CPU events to propagate to multiple connected systems
Key Features
PCI interface integration with iHawk multiprocessing architecture
Custom interrupt source injection via external input lines
Distributed interrupt chaining for multi-system event coordination
Full RedHawk Linux driver support
Typical Applications Real-time simulation, distributed data acquisition, industrial control systems requiring synchronized multi-CPU event handling, and time-critical process scheduling.
Compatibility & Integration Designed for Concurrent iHawk systems running RedHawk Linux real-time operating system.
