Document Type and Number:
Japanese Patent JPS5924456
Kind Code:
B2
Abstract:
The invention concerns a disk file controller for the transfer of data from a parallel by bit interface to a serial by bit disk file interface. …A data channel has a data register (9), serializing and deserializing means (50 and 53) and a variable frequency oscillator to transfer parallel by bit data received by the register (9) from a DCI BUS OUT to be recorded serially by bit on a disk file. Alternatively the data channel receives serial by bit data read from a disk file and transfers it through the data register (9) in parallel by bit form to a DCI BUS IN. The several units of the data channel are controlled by a control register (28) supplied from a microprocessor (6). The microprocessor receives data selectively from the DCI BUS OUT and from the data register (9). Changes in format of the disk file data can be accommodated by the microprocessor (6) without need to change special purpose formatting hardware.
