摘要： In an approach, a processor receives a plurality of first operand values, where the first operand values are integer values. A processor adds, using binary addition, the plurality of first operand values resulting in a sum value S. A processor determines a single combined modular correction term D for a binary sum of all operand values based on leading bits of the sum value S. A processor performs a modular addition of S and D resulting in a modular sum of said plurality of said first operand values.

摘要： A combined binary/decimal fixed-point multiplier that uses BCD-4221 recoding for the decimal digits. This allows the use of binary carry-save hardware to perform decimal addition with a small correction. The described designs provide an improved reduction tree organization to reduce the area and delay of the multiplier and improved reduction tree components that leverage the redundant decimal encodings to help reduce delay. A split reduction tree architecture is also introduced that reduces the delay of the binary product with only a small increase in total area. Area and delay estimates are presented that show that the proposed designs have significant area improvements over separate binary and decimal multipliers while still maintaining similar latencies for both decimal and binary operations.

摘要： A digital arithmetic unit employing a binary adder for adding and subtracting multidigit binary coded decimal numbers in either zoned format or packed format and having an improved method of generating parity check bits for the resultant data bytes produced by the arithmetic unit. When using a binary adder for adding or subtracting binary coded decimal numbers, it is necessary to correct some of the data appearing at the output of the binary adder in order to obtain the correct results. The parity check bit generating circuitry of the present invention, however, works on the uncorrected data appearing at the output of the adder, but nevertheless produces the proper parity check bits for the corrected data which represents the final output for the arithmetic unit. This reduces the amount of time delay which would otherwise be caused by generating the parity check bits in a conventional manner.
摘要翻译：一种采用二进制加法器的数字运算单元，用于以分区格式或打包格式对多位二进制编码十进制数进行加法和减法，并且具有为运算单元产生的结果数据字节产生奇偶校验位的改进方法。当使用二进制加法器对二进制编码十进制数进行加法或减法时，需要校正出现在二进制加法器的输出端的一些数据，以获得正确的结果。然而，本发明的奇偶校验位产生电路对于出现在加法器的输出端的未校正数据起作用，但是对于表示算术单元的最终输出的校正数据产生适当的奇偶校验位。这减少了以常规方式生成奇偶校验位的另外时间延迟的量。

摘要： A semiconductor device capable of performing arithmetic operation with low power consumption is provided. The semiconductor device includes first and second circuits, a first amplifier circuit, first to fourth switches, and a capacitor, the first circuit is electrically connected to a first wiring, and the second circuit is electrically connected to a second wiring.

The first terminal of the capacitor is electrically connected to a first terminal of the second switch, and a second terminal of the capacitor is electrically connected to the first amplifier circuit through the fourth switch. Current corresponding to the result of product-sum operation flows through each of the first and second wirings, and the current is converted into potentials by the first and second circuits. A difference between the converted potentials is held in the capacitor, and the difference is input to the first amplifier circuit and is output as a potential corresponding to the arithmetic operation result.

摘要： A system for prioritizing a cache of print jobs associated with at least one print driver includes a workstation having a processing unit and at least one print driver having a processing unit, that interface via a network. The workstation implements a print job request for a document and determines whether a document key identifier associated with the document exists. If not, a key is created. If a printer-readable format for a document associated with the key identifier is stored in or is pre-existing in one of at least two caches, the print driver assigns a prioritization identifier to the format. The system retrieves the printer-readable format from the cache to produce a print job output. Since the cache stores the document in printer-readable format, overall printing time is reduced. The format may be moved from one cache to another depending upon priority. The corresponding method is also disclosed.
摘要翻译：用于对与至少一个打印驱动程序相关联的打印作业的高速缓存进行优先排序的系统包括具有处理单元的工作站和具有经由网络进行接口的处理单元的至少一个打印驱动程序。工作站对文档执行打印作业请求，并确定与文档相关联的文档关键字标识是否存在。如果没有，则创建一个密钥。如果与密钥标识符相关联的文档的打印机可读格式存储在至少两个高速缓存之一中或者已经存在于至少两个高速缓存之一中，则打印驱动程序为该格式分配优先级标识符。系统从高速缓存中检索打印机可读格式以产生打印作业输出。由于缓存以打印机可读格式存储文档，所以整体打印时间减少。取决于优先级，格式可以从一个缓存移动到另一个缓存。还公开了相应的方法。
