ABSTRACT:
A system is disclosed which enables measurement of the elapse of a predetermined time period in a computer system by determining the speed of instruction cycle execution according to the number of instruction cycles occurring relative to system clock transitions. The result is a timing reference tailored for a specific function which is not intrusive of the system clock in the computer system, and is determined independently of the particular timing characteristics of the system. The elapsed time value corresponds to a function such as the time period for processing a data transfer command received by a CD-ROM drive. The system clock of the computer is used as a known timing reference and a software counter is incremented upon a transition in the system clock until the next transition in the system clock.
