Abstract
A pointer representation includes a permission field to define capabilities of the system in processing the data to which an address in the pointer of representation points. Bounds of the memory segment to which the capabilities apply are defined by a block field, which defines a block size, and a length field, which defines a number of blocks of that size within the segment of memory. To permit computation of the full range of addresses to which the capability applies, a finger field is included to denote the block of the segment of memory to which the address points. An increment-only bit may cause the system to preclude any negative offsets from the address in the pointer representation. Subsegments within a segment may be further defined by additional block, length and finger fields.
