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.

Abstract translation: 使用并行处理将一组终止的字符数据的字符从一个存储器位置复制到另一个存储器位置，并且不引起无理的异常。 要复制的字符数据被加载到一个或多个向量寄存器中。 特别地，在一个实施例中，使用将矢量寄存器中并行的数据加载到指定边界的指令（例如，向量块向量边界指令），并且提供了确定加载的字符数的方法。 为了确定加载的字符数（计数），使用另一条指令（例如，向块边界指令的加载计数）。 此外，使用指令（例如，矢量查找元素不等于指令）来找到第一分隔符字符的索引，即第一终止字符，例如字符数据内的零或空字符。 该指令并行地检查多个字节的数据。

Abstract: An operation is provided to signal a processor that action is to be taken to facilitate execution of a transaction that has aborted one or more times. The operation is specified within an instruction or is itself an instruction. The instruction is executed based on detecting an abort of the transactions, and includes a field indicating how many times the transaction has aborted. The processor uses this information to determine what action is to be taken.

Abstract: A Load to Block Boundary instruction is provided that loads a variable number of bytes of data into a register while ensuring that a specified memory boundary is not crossed. The boundary may be specified a number of ways, including, but not limited to, a variable value in the instruction text, a fixed instruction text value encoded in the opcode, or a register based boundary.

Abstract: A Load Count to Block Boundary instruction is provided that provides a distance from a specified memory address to a specified memory boundary. The memory boundary is a boundary that is not to be crossed in loading data. The boundary may be specified a number of ways, including, but not limited to, a variable value in the instruction text, a fixed instruction text value encoded in the opcode, or a register based boundary; or it may be dynamically determined.

Abstract: Multiple sets of character data having termination characters are compared using parallel processing and without causing unwarranted exceptions. Each set of character data to be compared is loaded within one or more vector registers. In particular, in one embodiment, for each set of character data to be compared, an instruction is used that loads data in a vector register to a specified boundary, and provides a way to determine the number of characters loaded. Further, an instruction is used to find the index of the first delimiter character, i.e., the first zero or null character, or the index of unequal characters. Using these instructions, a location of the end of one of the sets of data or a location of an unequal character is efficiently provided.

Abstract: A TRANSACTION BEGIN instruction begins execution of a transaction and includes a general register save mask having bits, that when set, indicate registers to be saved in the event the transaction is aborted. At the beginning of the transaction, contents of the registers are saved in memory not accessible to the program, and if the transaction is aborted, the saved contents are copied to the registers.

Abstract translation: TRANSACTION BEGIN指令开始执行一个事务，并包含一个通用寄存器保存掩码，该掩码包含位，该位在置位时指示要在事务中止时保存寄存器。 在事务开始时，寄存器的内容被保存在程序无法访问的内存中，如果事务中止，保存的内容将被复制到寄存器中。

Abstract: Machine instructions, referred to herein as a long Convert from Zoned instruction (CDZT) and extended Convert from Zoned instruction (CXZT), are provided that read EBCDIC or ASCII data from memory, convert it to the appropriate decimal floating point format, and write it to a target floating point register or floating point register pair. Further, machine instructions, referred to herein as a long Convert to Zoned instruction (CZDT) and extended Convert to Zoned instruction (CZXT), are provided that convert a decimal floating point (DFP) operand in a source floating point register or floating point register pair to EBCDIC or ASCII data and store it to a target memory location.
