摘要： An instruction is executed in round-for-reround mode wherein the permissible resultant value that is closest to and no greater in magnitude than the infinitely precise result is selected. If the selected value is not exact and the units digit of the selected value is either 0 or 5, then the digit is incremented by one and the selected value is delivered. In all other cases, the selected value is delivered.

摘要： An instruction to perform an operation selected from a plurality of operations configured for the instruction is executed. The executing includes determining a value of a selected operand of the instruction. The determining the value is based on a control of the instruction and includes reading the selected operand of the instruction from a selected operand location to obtain the value of the selected operand, based on the control having a first value, and using a predetermined value as the value of the selected operand, based on the control having a second value. The value and another selected operand of the instruction are multiplied to obtain a product. An arithmetic operation is performed using the product and a chosen operand of the instruction to obtain an intermediate result. A result from the intermediate result is obtained and placed in a selected location.

摘要： Vector pack and unpack instructions are described. An instruction to perform a conversion between one decimal format and another decimal format is executed, in which the one decimal format or the other decimal format is a zoned decimal format. The executing includes obtaining a value from at least one register specified using the instruction. At least a portion of the value is converted from the one decimal format to the other decimal format different from the one decimal format to provide a converted result. A result obtained from the converted result is written into a single register specified using the instruction.

摘要： An instruction to perform converting and scaling operations is provided. Execution of the instruction includes converting an input value in one format to provide a converted result in another format. The converted result is scaled to provide a scaled result. A result obtained from the scaled result is placed in a selected location. Further, an instruction to perform scaling and converting operations is provided. Execution of the instruction includes scaling an input value in one format to provide a scaled result and converting the scaled result from the one format to provide a converted result in another format. A result obtained from the converted result is placed in a selected location.

摘要： A method of instruction dispatch routing comprises receiving an instruction for dispatch to one of a plurality of issue queues; determining a priority status of the instruction; selecting a rotation order based on the priority status, wherein a first rotation order is associated with priority instructions and a second rotation order, different from the first rotation order, is associated with non-priority instructions; selecting an issue queue of the plurality of issue queues based on the selected rotation order; and dispatching the instruction to the selected issue queue.

摘要： Aspects of the invention include receiving a first dictionary that includes key/value pairs for a first code listing. Key instances of the first dictionary include instruction addresses of the first code listing, and value instances of the first dictionary include hashes of data that uniquely identify instructions at the instruction addresses in the first code listing. A second dictionary that includes key/value pairs for a second code listing is received. Key instances of the second dictionary include hashes of data that uniquely identify instructions at instruction addresses in the second code listing, and value instances of the second dictionary include instruction addresses of the second code listing. A match between a value instance of the first dictionary and a key instance of the second dictionary is identified. Responsive to identifying the match, an instruction address is translated between the first code listing and the second code listing.
