Abstract

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 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 data and index of the register batch after the master registers of the encoder controller are updated into the slave registers of the encoder controller. The encode controller generates control signals to a recording circuit depending on updated slave registers. Such control signals causes the recording circuit to record a signal representative of signal data on a recordable disk located in a recordable disk driver.

Subsequently, the CD-R / CD-RW controller 12 transmits the command to the microcontroller 13 and generates a series of control signals to cause the CD-R / CDRW controller 12 to record the signal representing the signal lean in the CD-R / CD — Rw disc. (3) r / cd-The controller 12 stores the signal data received from the main processor 丨 〖14 in the buffer ^ 14. In response to a control signal generated by the microcontroller 13,

Cf // CD RW controller 1 2 captures signal data from the buffer 丨 4 and generates a recording signal to record the signal representing the signal data in the CD-R / CD- located in the CD-r / cd-Rw drive 15 RW disc. To generate this control signal, the microcontroller 3 generates a table corresponding to each π 7 (step 2 shown in FIG. 1 (b)) and generates a control signal from the table. ROM 16 stores the information used to generate this form, and microcontroller 13 accesses ROM 16 accordingly to generate a form corresponding to a command. At f, the table contains the information needed to encode the signal data on several sectors during the recording operation. In the known multimedia computer system 10, the microcontroller 13 stores a table corresponding to the I2n command in the RAM 17 (^ I #a shown in FIG. 1). Then, the microcontroller 1 3 from RAM 1 7 accesses this table, and the favorable information generates a control signal to the step UG shown in the CD-R / CD-RW controller 12). Due to the existence of this access step, the data state 1 3 potentially needs to access the RAM 17 in order to generate a control signal for recording signal data on the mother-sector sector. , Pq%: It is a pity that the conventional multimedia computer system 10 has the following micro-controls.

A recordable light is used to receive a series of $ 2 from a host processor. : The data buffer manager accesses from the host interface: the 7:;-command. Alas, and the command is transmitted to the microcontroller. ^ ° Following the command and the controller from each command five, the index of the invention description (4): ί two :: two ,, and the transfer of register data and batch register micro-control cry = Two two-state controller. The entire batch of register controllers will receive the index of the batch and register batches from the receiver and will be connected. , / 4 /, g register batch index is stored in a whole batch of buffer register batches, ί m? = The controller retrieves the slave temporary storage of the temporary device from the entire batch of buffers: internal :; system ; The master register is updated to the encoder control and register data, and the slave register of the register index controller based on the batch of the register of the second register is the master register of m ::. After the encoder performs the work, it should be replaced by the previous slave register. The register generates a control letter to the slave register circuit based on the updated slave register according to the I = state controller. ㈣ The control signal causes the recordable disc on the record to be recorded. And '4' are recorded on a recordable optical disc drive. Therefore, in the present invention, the device data is recorded.
