COALESCING STAGES IN A MULTIPLE STAGE COMPLETION SEQUENCE

摘要

Embodiments are directed to systems and methodologies for allowing a computer program code to efficiently respond to and process events. For events having a multiple stage completion sequence, and wherein several of the events occur within relatively close time proximity to each other, portions of the multiple stages may be coalesced without adding latency, thereby maintaining responsiveness of the computer program. The disclosed coalescing systems and methodologies include state machines and counters that in effect “replace” certain stages of the event sequence when the frequency of events increases.

主权项

1. A computer system for notifying a computer program of events, the system comprising:
a memory; a tracking circuit comprising at least one counter; and a processor communicatively coupled to the tracking circuit and the memory; wherein the computer system is configured to perform a method comprising:
determining, by the tracking circuit, that events have occurred, wherein a total number of the events comprises a range from 1 to N, wherein N comprises a predetermined number;determining, by the tracking circuit, that 1 to N events occurred in succession and within a predetermined time of each other;in response to determining, by the tracking circuit, that 1 to N events occurred in succession and within a predetermined time of each other, delaying transmitting an event notification and location alert for any one of the 1 to N events to the computer program until after the N event occurs;in response to determining, by the tracking circuit, that the N event occurred, temporarily suspending receipt of subsequent events and transmitting to the computer program an event notification and location alert of at least one of the 1 to N events; wherein the event notification and location alert of the at least one of the 1 to N events provides a notification to the computer program comprising at least the following:
that the at least one of the 1 to N events occurred: andinformation about a location of the at least one of the 1 to N events; wherein the alert comprises:
setting an interrupt request; andsetting at least one pointer; wherein setting the at least one pointer comprises setting at least one summary bit that points to a bit vector; wherein the bit vector points to a location in the memory that holds an event description representing the at least one of the 1 to N events; wherein the computer program uses the event notification and location alert of the at least one of the 1 to N events to provide event notification and location alerts for all of the 1 to N events.
