Abstract
Copying characters of a set of terminated character data from one memory location to another memory location using parallel processing and without causing unwarranted exceptions. The character data to be copied is loaded within one or more vector registers. In particular, in one embodiment, an instruction (e.g., a Vector Load to block Boundary instruction) is used that loads data in parallel in a vector register to a specified boundary, and provides a way to determine the number of characters loaded. To determine the number of characters loaded (a count), another instruction (e.g., a Load Count to Block Boundary instruction) is used. Further, an instruction (e.g., a Vector Find Element Not Equal instruction) is used to find the index of the first delimiter character, i.e., the first termination character, such as a zero or null character within the character data. This instruction checks a plurality of bytes of data in parallel.
