摘要 |
<p>The process involves determining a result on several bits as indicated by respective conditions, where the result corresponds to an operation including a fixed value and an input data. An address of a jump operation is calculated from the result. Blocking instructions are calculated from a program, where the instructions are placed at addresses to perform the jump operation when a variable does not satisfy a condition. An independent claim is also included for a process executing a program.</p> |
