Patent ID: 8694740

Claim:
A counters array system, comprising a memory device having a plurality of addressable memory locations for storing counter-values; and a plurality of delta-counter devices, each operable to hold a maximum delta-value corresponding to a maximum number of occurrences of an event during a time duration between two counter scans controlled by a scan control unit, and each of said plurality of delta-counter devices comprises an input connected to receive a signal from an event source corresponding to an occurrence of said event, and an output connected to provide a delta-value representing an accumulated number of occurrences of said event to a delta-count update circuit, wherein said delta-count update circuit is coupled to said memory device and said scan control unit, and said delta-count update circuit is configured to receive said delta-value and address of a corresponding counter-value, read said counter-value from said memory device, and provide an updated counter-value incremented by said delta-value to said memory device.
