Abstract:
A data-transfer interconnection for signal and data transfer between a CD-ROM decoder and a buffer memory associated with the CD-ROM decoder, the CD-ROM decoder including a data I/O port for data transfer of a total of a first number of bits and the buffer memory including a data I/O port for data transfer of a total of a second number of bits, where the second number is greater than the first number, the second number of bits being partitioned into a high-segment portion and a low-segment portion;the data-transfer interconnection comprising:an address bus for transferring an addressing signal from the CD-ROM decoder to the buffer memory;a write-enable signal line for transferring a write-enable signal from the CD-ROM decoder to the buffer memory;an output-enable signal line for transferring an output-enable signal from the CD-ROM decoder to the buffer memory;a row-address strobe signal line for transferring a row-address strobe signal from the CD-ROM decoder to the buffer memory;a low-segment column-address strobe signal line for transferring a low-segment column-address strobe signal from the CD-ROM decoder to the buffer memory;a high-segment column-address strobe signal line for transferring a high-segment column-address strobe signal from the CD-ROM decoder to the buffer memory; anda data bus including a total of bit lines equal to the first number, said data bus having a first end connected to the I/O port of the CD-ROM decoder and a second end connected both to the high-segment portion and the low-segment portion of the I/O port of the buffer memory.
