Asynchronous Event Support

xPC Target incudes support for asynchronous events. These events are triggered by a hardware interrupt asynchronously to normal execution. Some I/O boards raise interrupts that the CPU can use to interrupt the normal execution of code and jump to another sections of code called an Interrupt Service routine (ISR).

This section includes the following topics:

• Adding an Asynchronous Event -- Add an Async IRQ Source block to your Simulink model
• Async IRQ Source Block -- Reference for block parameters
• Async Rate Transition Block -- Reference for block parameters
• Async Buffer Write and Read Blocks -- Reference for block parameters
• Asynchronous Interrupt Examples -- Examples for data transfer with a Transition block, buffered data transfer with Real/Write blocks, and interrupt CAN communication with PCI and PC/104 boards
