摘要： A microprocessor includes a register and a comparator. The register stores an address area, the address area requiring a guarantee of an access order. The comparator compares an address of the address area held in said register with an address of an address area indicated in an access request from CPU, and outputs a signal to execute an access request succeeding the access request from the CPU after executing an access request preceding the access request from the CPU when the address area indicated in the access request from the CPU matches the address area held in said register.

摘要： An encoder converts a binary data word to a binary code word. The encoded bits have first and second binary values at a predetermined clock interval. A pulse generator responds to the encoded bits to generate energizing pulses during each clock interval in which the encoded bits have the first binary value. The energizing pules have a uniform duration less than the clock interval. A laser responds to the energizing pulses for recording on a medium.

摘要： A first write encoder encodes digital data in a first, high-density format. A second write encoder encodes digital data in a second, low-density (i.e., ANSI) format. A first read decoder decodes digital data from the first format. A second read decoder decodes digital data from the second format. A disk drive receives a replaceable 90 millimeter optical disk. A read/write head reads encoded data from and writes encoded data to a 90 millimeter optical disk received by the drive. In a first mode, the first write encoder is connected between a source of digital data and the read/write head, and the first read decoder is connected between the read/write head and the utilizing apparatus. In a second mode, the second write encoder is connected between the source and the read/write head, and the second read decoder is connected between the read/write head and the utilizing apparatus. Control electronics switch between the first and second modes, depending upon the format in which data is recorded on the disk received by the disk drive. An 8/9 GCR encoder and a laser pulse generator are used in the first write encoder to record data on the optical media to increase the storage capacity. Improvement in timing is accomplished with write compensation and signal equalization.

摘要： A method for interline-coding a facsimile signal, in which information of scanning lines of the input facsimile signal is alternately divided into information of at least one first unit line and information of at least one second unit line. A first one of the first unit lines is first coded in accordance with a predetermined coding principle. The information of the next one of the first unit lines is secondly coded in accordance with a predetermined coding principle prior to coding of information of the first one of said second unit lines. The information of the first one of the second unit lines is thirdly coded by two-dimensional predictive coding using, as reference information, the information of the first one and the next one of the first unit lines. The operations of the second coding and the operation of the third coding are repeatedly achieved thereafter.
