A large number of frequent events may be accurately counted by employing a shift register. The values of several bit positions within the shift register are logically combined to generate an input to the shift register. The input is shifted in to alter the register contents whenever an event to be counted occurs. The bit positions for generating the input are selected to produce the longest sequence of nonrepeating patterns possible. The event counter may be implemented in a small area, allowing a large number of event counters to be implemented in an array like structure within a single device and to operate as extremely high frequencies.

[ What is claimed is:] [1.] A method of counting a large number of high speed events, comprising:initializing a fixed width bit pattern;generating an input value from a plurality of bits within said bit pattern; andresponsive to occurrence of a selected event, shifting said input value into said bit pattern, wherein a tabular bit pattern corresponding to a count of said selected events is generated.
