Recordable disk recording controller with batch register controller

摘要

In a recordable disk recording controller circuit, a data buffer manager receives a command and sends the command to a micro-controller. The micro-controller generates a set of register batches from each command and sends the register data and index of the register batch to a batch register controller. The batch register controller receives the register data and index of the register batch from the micro-controller and stores the received register data and index of the register batch in a batch buffer. The batch register controller retrieves the register batches from the batch buffer and writes the master registers of an encoder controller based on the register index and register data of the register batches after the master registers of the encoder controller are updated into the slave registers of the encoder controller. The encoder controller generates control signals to a recording circuit depending on updated slave registers. Such control signals cause the recording circuit to record a signal representative of signal data on a recordable disk located in a recordable disk driver.
