    摘要: An address translation apparatus comprises: entry storage means for storing a plurality of entries, each entry containing a virtual page number, a physical page number, and a process identifier which is composed of plural bits; comparison information storage means for storing comparison information which defines a method for comparing a process identifier possessed by a process that is currently executed, with the process identifier in each entry; process comparison means for comprising the process identifier possessed by the process that is currently executed, with the process identifier in the entry, on the basis of the comparison information; and entry retrieval means for retrieving, from the entry storage means, an entry including a virtual page number equal to a virtual page number supplied from the outside, and a process identifier which matches the process identifier of the currently executed process, according to the result of comparison by the process comparison means. Therefore, when a physical memory has a content which can be shared between at least two processes, effective utilization of memory area can be achieved by unifying entries with respect to these processes.

    摘要: A single data output terminal and an output portion having a pair of output control terminals for generating a ternary output, are disposed for a plurality of data input terminals and a plurality of control input terminals in the same number as that of the data input terminals. Input changeover portions have (i) a state where data signals can be entered into the output control terminals and (ii) a state where the data signals cannot be entered into the output control terminals. An input control portion supplies, according to the states of control signals entered therein, a changeover signal for switching the input changeover portions to (i) a mode in which one of the input changeover portions is set to the conductive state, or (ii) a mode in which all of the input changeover portions are set to the non-conductive state. According to the states of entered control signals, an output control portion controls the output portion such that a high impedance signal is supplied according to a changeover signal for setting all of the input changeover portions to the non-conductive state, and that there is generated an output signal identical with the value of an entered binary data signal according to a changeover signal for setting one of the input changeover portions to the conductive state.

    摘要: The present invention has for its object to provide a data processing apparatus which improves the point that in data processing employing an associative storage device, performing the high speed processing has been impossible in the full-associative constitution since each way (entry) is subjected to the sequential processing respectively in search processing. The data processing apparatus includes a TLB comprising an information pair specifying information means (RP), a first information holding means (PTE-Hi), and a second information holding means (PTE-Lo). The high speed processing against information held in a TLB memory section is realized by performing the search processing employing information held in the above-mentioned means.
