摘要：
A way is provided to protect memory blocks from unauthorized access from executable instructions by defining various sets of instructions that are specifically bound to operate on defined memory blocks and inhibited from operating in other memory blocks. For instance, executable code may include a plurality of distinct read and write instructions where each read and/or write instruction is specific to one memory access tag from a plurality of different memory access tags. Memory blocks are also established and each memory block is associated with one of the plurality of different memory access tags. Consequently, if a first read and/or write instruction, associated with a first memory access tag, attempts to access a memory block associated with a different memory access tag, then execution of the first read and/or write instruction is inhibited or aborted.
摘要（中）：
提供了一种方式来通过限定特定绑定以对定义的存储器块进行操作并禁止在其他存储器块中操作的各种指令集来保护存储器块免于从可执行指令的未经授权的访问。 例如，可执行代码可以包括多个不同的读取和写入指令，其中每个读取和/或写入指令是特定于来自多个不同存储器访问标签的一个存储器访问标签。 还建立了存储器块，并且每个存储块与多个不同的存储器访问标签之一相关联。 因此，如果与第一存储器访问标签相关联的第一读取和/或写入指令尝试访问与不同存储器访问标签相关联的存储器块，则禁止或中止第一读取和/或写入指令的执行。
