摘要： In an electric discharge machine, wherein electric power is supplied between an electrode and a workpiece to machine the workpiece, a jumping motion is performed to temporarily increase a distance between the electrode and the workpiece. The electric discharge machine includes a detector for detecting a machining reaction force; a setting unit for setting a specified value of the machining reaction force; a comparator for comparing a detected value of the machining reaction force with a specified value of the machining reaction force; and a changing unit for changing a locus of the jumping motion so that the machining reaction force can be reduced if the comparator finds that the detected value of the machining reaction force is greater than the specified value of the machining reaction force.

摘要： Disclosed is a compiler apparatus for generating an instruction code composed of instruction sets each including an instruction that designates an m-bit immediate value indicating a location of a data item in a memory area. The compiler apparatus sequentially selects, based on one data attribute, a data item from a group X composed of a plurality of data items; and judges, each time a data item is selected, whether the selected data item is allocatable to an n-byte memory area (n≦2m). When the judgment is negative, the compiler apparatus specifies, based on a different data attribute, a data item out of all the selected data items and excludes the specified data item from the group X, and repeats the selection until all the data items remaining in the group X after excluding specified data items are judged to be allocatable to the memory area.

摘要： An optimization apparatus is capable of improving the execution efficiency of a loop that includes a loop carry dependency between consecutive iterations of the loop. For example, a value resulting from one iteration is used in an immediately following iteration. When the arithmetic expression “a[i+1]=a[i]*3+2;” is included in a loop body, and a value resulting from the arithmetic expression “a[i+1]=a[i]*3+2;” in one iteration is used in a following iteration, execution delays occur in pipeline processing of the loop. Here, the arithmetic expression “a[i+1]=a[i]*3+2;” is transformed into the arithmetic expression “a[i+4]=a[i]*81+80;” to expand the dependency distance. By doing so, the execution delays can be decreased.
摘要翻译：优化装置能够提高循环的执行效率，该循环在循环的连续迭代之间包括循环进位依赖性。例如，由一次迭代产生的值在紧随其后的迭代中使用。当算术表达式“a [i + 1] = a [i] * 3 + 2;” 被包含在循环体中，并且由算术表达式“a [i + 1] = a [i] * 3 + 2]得到的值; 在一次迭代中，在下一次迭代中使用，在循环的流水线处理中出现执行延迟。这里，算术表达式“a [i + 1] = a [i] * 3 + 2;” 被转换成算术表达式“a [i + 4] = a [i] * 81 + 80;” 扩大依赖距离。通过这样做，可以减少执行延迟。
