摘要： When a CPU (1) writes "10" into a register (RG) provided in a controller (5), an AND gate (10) receives a CPU clock mask signal (CMS1) having the logic of "0" by one of its input terminals and accordingly cuts off the supply of a clock signal CLK to the CPU (1). Then, the CPU (1) is suspended, thereby reducing power consumption of the CPU (1). To return out of this state, a user has only to input an interrupt request to the controller (5) through a terminal (T1). Receiving the request, the controller (5) outputs the CPU clock mask signal (CMS1) having the logic of "1" to one of the input terminals of the AND gate (10) so as to supply the CPU (1) with the clock signal (CLK) again. Upon restarting the supply of the clock signal (CLK), the CPU (1) starts an operation to implement the interrupt request. With this configuration, an integrated circuit device including a control circuit for controlling operations of a processing circuit and a memory circuit with excellent operability can be provided.
摘要翻译：当CPU（1）将“10”写入到控制器（5）中提供的寄存器（RG）中时，与门（10）通过其中的一个接收具有逻辑“0”的CPU时钟屏蔽信号（CMS1）输入端子，从而切断向CPU（1）提供时钟信号CLK。然后，CPU（1）暂停，从而降低CPU（1）的功耗。为了退出该状态，用户仅通过终端（T1）向控制器（5）输入中断请求。接收到该请求后，控制器（5）将具有逻辑“1”的CPU时钟屏蔽信号（CMS1）输出到与门（10）的输入端之一，以向CPU（1）提供时钟信号（CLK）。在重新启动时钟信号（CLK）的提供时，CPU（1）开始执行中断请求的操作。利用这种配置，可以提供一种集成电路装置，其包括用于控制处理电路的操作的控制电路和具有优异的可操作性的存储电路。

摘要： A central processing unit (CPU) having a built-in dynamic random-access memory (DRAM) with exclusive access to the DRAM when the CPU performs an interlock access to the DRAM. A memory controller prevents the DRAM from being externally accessed while the CPU is performing the interlock access. When the memory controller receives an external request for accessing the DRAM during a time when the CPU is performing an interlock access to the DRAM, the memory controller outputs a response signal indicating that external access to the DRAM is excluded or inhibited. The request signal can be a hold request signal for requesting a bus right or can be a chip select signal. The response signal can be a hold acknowledge signal or a data complete signal. The memory controller can be switched to and from first and second lock modes, where hold request and hold acknowledge signals are used during the first lock mode and chip select and data complete signals are used in the second lock mode.

摘要： A data processor which is provided with a flag in a Processor Status Word (PSW) 116 for storing prohibiting/enabling status for receiving all of the interrupt requests, and in which the instruction execution control unit 114 controls so that the flag becomes in the enabling status when an interrupt request having a priority level is received and the flag becomes in the prohibiting status when an interrupt request having no priority level is received. Hence, for interrupt requests having priority levels, an interrupt request of high priority level can be received immediately without via the interrupt prohibiting status. For interrupt requests having priority levels, it becomes possible to receive an interrupt request of higher priority level without via the interrupt prohibiting status. For interrupt requests having no priority level such as for debugger and the like, it becomes unnecessary to perform a multi-interrupt processing.

摘要： Exemplary embodiments of the present invention are directed toward a technique which facilitates the process instruction codes in processor. According to the present invention, a memory device is provided which comprises a plurality of 2N-bit word boundaries, where N is greater than or equal to one. The processor of the present invention executes instruction codes of a 2N-bit length and a N-bit length. The instruction codes are stored in the memory device is such a way that the 2-N bit word boundaries contains either a single 2N-bit instruction code or two N-bit instruction codes. The most significant bit of each instruction code serves as a instruction format identifier which controls the execution (or decoding) sequence of the instruction codes. As a result, only two transfer paths from an instruction fetch portion to an instruction decode portion of the processor are necessary thereby reducing the hardware requirement of the processor and increasing system throughput.

摘要： For a processor having instruction codes of two instruction lengths (16 bits and 32 bits), methods of locating the instruction codes are limited to two types: (1) two 16-bit instruction codes are stored within 32-bit word boundaries, and (2) a single 32-bit instruction code is stored intactly within the 32-bit word boundaries. A branch destination address is specified only on the 32-bit word boundary. The MSB of each instruction code serves as a 1-bit instruction length identifier for controlling the execution sequence of the instruction codes. This provides two transfer paths from an instruction fetch portion to an instruction decode portion within the processor, achieving reduction in code side and in the amount of hardware and, accordingly, the increase in operating speed.
