Automated servo control system

A system for servo control in an optical drive, comprising:

• an ADC for obtaining a sample servo data;
• a digital servo control, wherein the digital servo control comprises a MAC coupled to the ADC, wherein the MAC is capable of automatically calculating a transfer function after an execution of the MAC is initiated;
• and
• a processor coupled to the digital servo control for initiating the execution of the MAC/wherein the MAC comprises:
• a first memory for storing a set of coefficients for the transfer function;
• a second memory coupled to the ADC for storing the sample servo data and an accumulated sample servo data;
• and
• a multiplier/accumulator coupled to the first and second memories for calculating the transfer function based upon the set of coefficients, the sample servo data, and the accumulated sample servo data.
