摘要： A microcomputer comprises a timer controller for detecting a time when a disabled state in which interrupts are disabled starts and a time when the disabled state ends, a count timer which starts a counting operation when the timer controller detects a time when the disabled state starts, for measuring a period of time during which interrupts are disabled, and a comparator which receives a current count value of the count timer when the disabled state ends, and, when determining that the current count value is larger than a maximum of count values previously received which is stored in a register for storing a maximum of interrupt-disabled time periods, stores the current count value in the register.

摘要： A program preparation apparatus that can reduce power consumption and that can suppress malfunctions and the occurrence of noise by improving software is provided. An assembler prepares a relative object program based on an assembly source program. Next, the assembler changes the order of instructions included in the assembly source program in a range that does not influence the operational results in a CPU and, thereby, prepares another assembly source program so as to prepare a relative object program based on this assembly source program. Next, the assembler finds the respective maximum Hamming distance values between respective instructions for a plurality of relative object programs so that the program of which the maximum Hamming distance value is the lowest is determined as a formal relative object program.
摘要翻译：提供了一种可以通过改进软件来降低功耗并且可以抑制故障和产生噪声的程序制备装置。汇编程序基于汇编源程序准备相对对象程序。接下来，汇编器将包含在汇编源程序中的指令的顺序改变在不影响CPU中的运算结果的范围内，从而准备另一个汇编源程序，以便根据该汇编源准备相对对象程序程序。接下来，汇编器找到多个相对对象程序的相应指令之间的相应最大汉明距离值，使得最大汉明距离值最低的程序被确定为正式的相对对象程序。

摘要： In a system call issue method and a debug system, during execution of a target program, data transfer is performed between an emulator and an OS kernel forming the target program through a memory field in a RAM. It is checked whether there is a system call issue request in the memory field and if there is the system call issue request in the memory field, the emulator issues a system call.
摘要翻译：在系统调用发布方法和调试系统中，在执行目标程序期间，通过RAM中的存储器字段在仿真器和形成目标程序的OS内核之间执行数据传输。检查内存字段中是否存在系统调用问题请求，如果在内存字段中存在系统调用问题请求，则仿真器发出系统调用。
