Abstract: An industrial control I/O module for interfacing with industrial control equipment, such as sensors and actuators, can be configured to dynamically provide differing resistances in each channel as may be required for reliably achieving particular modes of operation in the channel. Providing differing resistances in such channels flexibly allows different modes in the channel to provide universal I/O capability. Modes of operation could include, for example, digital output, digital input, analog output, analog input and the like, in the same channel, but at different times. In one aspect, a processor or voltage divider can be used to control an amplifier, with feedback, driving a transistor in a channel to dynamically adjust resistance in the channel by selectively biasing the transistor to achieve a resistance in the channel suitable for the selected mode.

Abstract: Systems, apparatuses, and methods for routing interrupts on a coherency probe network are disclosed. A computing system includes a plurality of processing nodes, a coherency probe network, and one or more control units. The coherency probe network carries coherency probe messages between coherent agents.

Interrupts are generated with a first encoding while coherency probe messages have a second encoding. Cache subsystems determine whether a message received via the coherency probe network is an interrupt message or a coherency probe message based on an encoding embedded in the received message. Interrupt messages are routed to interrupt controller(s) while coherency probe messages are processed in accordance with a coherence probe action field embedded in the message.

Abstract: Interrupt code conversion for efficient computer program recovery. In response to an error being detected while processing instructions of a computer program running on a computer system, the OS receives a first program interrupt code (PIC) and interrupts the computer program. Control of the computer program is passed to a program interrupt handler and the program interrupt handler inspects the first PIC issued as a result of detecting the error. The first PIC is converted to a second PIC wherein the second PIC is associated with another error predicted when subsequent running of the computer program occurs. The second PIC is presented to a recovery routine associated with the computer program and, in response to the detected error, running of the computer program is customized based on the second PIC rather than the first PIC.
