Abstract: PROBLEM TO BE SOLVED: To allow lower and upper bounds of an object pointed to by a pointer to be automatically checked during execution of a program in programming languages such as C and C++ programs. SOLUTION: A processor 200 has default registers 202 and bound registers 204 which represent hardware register extensions of the default registers. The bound registers 204 maintain the association of metadata with its corresponding data. By providing the association between the default registers 202 and the bound registers 204, the calling convention of these registers 202 remains the same. The metadata being held at the bound registers 204 may be used to specify a range of memory addresses which can be accessed (loaded/stored) using the processor 200. COPYRIGHT: (C)2011,JPO&INPIT

Abstract translation: 要解决的问题：允许在编程语言（如C和C ++程序）中执行程序期间自动检查由指针指向的对象的下限和上限。 解决方案：处理器200具有表示默认寄存器的硬件寄存器扩展的默认寄存器202和绑定寄存器204。 绑定寄存器204保持元数据与其相应数据的关联。 通过提供默认寄存器202和绑定寄存器204之间的关联，这些寄存器202的调用约定保持不变。 保留在绑定寄存器204的元数据可以用于指定可以使用处理器200访问（加载/存储）的存储器地址的范围。版权所有：（C）2011，JPO＆INPIT

Abstract: Eine Reihe von Standardregistern eines Prozessors wird in Metadatenregister auf dem Prozessor eines Computersystems erweitert. Die Standardregister haben darauf Daten gespeichert, während Metadaten, die mit den Daten in Beziehung stehen, separat in den Metadatenregistern gespeichert sind.
