摘要： PURPOSE:To simplify the program designing, by securing an alteration of the operation mode of an information processor which is based on a process of each word between the word address mode and the byte address mode. CONSTITUTION:An instruction based on a word access is read out to an instruction register IR from a memory device via a memory buffer register MBR. The instruction is decoded by a decoder DEC, and a switching signal is transmitted to each gate from a control circuit CTL in accordance with the decoded information. The circuit CTL is controlled by the switching signal given from a mode storing circuit MODE, and the gate open/close signal can be altered between the word address mode and the byte address mode. As a result, a process of each byte is possible to simplify the program designing without altering nor lowering the functions of various types of instructions in the word address mode.

摘要： PURPOSE:To improve the efficiency of interruption, to speed processing, and to make the interruption flexible, by automatically securing a work area, used by the stand-by and interruption processing program of a register during interruption, through hardware. CONSTITUTION:In an interruption processing program, the 1st control information field WAS for specifying a register RSA to be enqueued in a stack and the 2nd control information field RSP for specifying the size of a work area WA used by the interruption processing program are provided. Once interruption is caused, the contents of the register are enqueued in the register stand-by area RSA in the stack in accordance with the 1st control information field WAS, and the work area WA is secured in the stack in accordance with the 2nd control information field RSP.

摘要： PURPOSE:To make it possible to transmit a large amount of information with a few signals by attaining time-division multiplication through parallel-to series conversion of several signals by a single pulse such as a clock. CONSTITUTION:Once clock CLK is applied, parallel-series converting sending circuit 1 latch signals A to D and pulse generating circuit 2 generates string M of pulses as much as signals A to D and then applies it to parallel-series converting sending circuit 1. Using this pulse string M as clocks, signals A to D are converted into series signals and then converted into BRZ (binary return zero) signal L before being sent out. Since the transmitting signal has been converted into BRZ signal L, extracting clocks is simplified and in device Y, clock extraction circuit 4 extracts clocks. By clocks, the BRZ signal is converted intup parallel signal A to D by series- parallel converting receiving circuit 3.

摘要： PURPOSE:To generate a versatile interrupt destination address with a simple circuit, by gathering plural interruption sources to make them into binary data and providing a means which uses this binary data as an address to access a random access memory. CONSTITUTION:Plural interruption sources ISi (i=0-n) are gathered to make them into binary data IS0-ISn and are inputted as addresses of a ROM. When a signal which prescribes the timing of generation of an interrup address is given as a chip enable signal CG, output information A0-Am (binary) indicating the interrupt destination address are outputted after the access time designated for the ROM.
摘要翻译：目的：通过收集多个中断源使其成为二进制数据，并提供一种使用该二进制数据作为地址来访问随机存取存储器的手段，以简单的电路生成通用的中断目标地址。构成：收集多个中断源ISi（i = 0-n）使其成为二进制数据IS0-ISn，并作为ROM的地址输入。当指定了产生中断地址的定时的信号作为芯片使能信号CG时，指定中断目的地地址的输出信息A0-Am（二进制）在为ROM指定的访问时间之后被输出。
