Abstract
In a processor having hardware event signals, signals are dynamically allocated in a mask to indicate whether each of the respective signals is available. Program code can use the same signal for multiple non-concurrent operations. A tag for an operation, such as an I/O operation can provide signal virtualization. In one embodiment, the tag includes a signal pending mask and a received signal mask. A comparison the mask can identify when an operation is complete.
