Abstract
The present invention provides a method and system for servo control in an optical drive. The method includes initiating an execution of a multiplier and accumulator controller (MAC) by a processor; and automatically calculating a transfer function by the MAC based upon a sample servo data. The present invention provides a servo control system which utilizes a MAC which is directly linked to the sample servo data. When a processor commands the MAC to execute, the MAC receives the sample servo directly from an Analog-to-Digital Converter (ADC); retrieves the corresponding accumulated sample servo data from a memory; calculates the transfer function; and stores the results back into the memory. The processor then accesses the memory to retrieve the result. Because the MAC is able to calculate the transfer function with minimal intervention from the processor, significant processing resources and time are saved.
