摘要： A microprogrammed commercial instruction processor (CIP) is placed in a stall mode during the transfer of information between the CIP and main memory by stalling a free running clock signal. When the transfer of information is completed, the free running clock cycles. If main memory indicates an error condition, then the free running clock signal is again stalled after one cycle to allow the firmware in the CIP to process the error.

摘要： A data processing system executes a decimal multiply instruction by storing the product of a multiplier decimal digit and a multiplicand decimal digit in a read only memory and storing partial product decimal digits in a register. The units product decimal digit is read from the read only memory during one cycle and added to a partial product decimal digit. A resulting units carry is stored in a units carry flip-flop. The tens product decimal digit is read from the read only memory during another cycle and added to a higher order partial product decimal digit. A resulting tens carry is stored in a tens carry flip-flop. A multiplexer selects the output of the units carry flip-flop for adding the units carry during the next units cycle in which the next units product decimal digit is added to the higher order partial product decimal digit. The multiplexer selects the output of the tens carry flip-flop for adding the tens carry during the next tens cycle in which the next tens product decimal digit is added to a next higher order partial product decimal digit.

摘要： A microprogrammed controlled commercial instruction processor coupled to a common bus executes a diagnostic microprogram to check the data path of the common bus interface registers and their associated internal registers. Decoded bits of a predetermined microword of the diagnostic microprogram generate a signal which transfers a predetermined data word containing a plurality of bytes stored in a first of the internal registers sequentially through the interface registers to a second of the internal registers during one microword cycle. Apparatus generates bad parity for selected bytes. Subsequent microwords compare the contents of the first and second internal registers and verify the detection of the "bad" parity.

摘要： A data processing system which includes a commercial instruction processor for executing decimal alphanumeric instructions uses read only memories in the alignment of the operands. The characteristics of the operands, string or packed decimal, as well as the length and position of the most significant decimal digit in a main memory word, are specified by data descriptors. The read only memories are responsive to the data descriptor information as well as the instruction being executed to generate signals which specify whether the direction words are read from main memory, high order word first or low order word first, the number of double words in the operand and the location of the least or most significant decimal digit within the word as stored in registers of the commercial instruction processor.

摘要： A commercial instruction processor executes a decimal divide instruction by counting the number of subtractions by the divisor resulting in a positive remainder to develop the quotient. Apparatus compares the most significant decimal digit of the divisor with the most significant decimal digit of the remainder after each subtraction pass to predict if the next subtraction pass would result in a negative remainder. If so, a quotient decimal digit is stored in a memory, the divisor is shifted one decimal digit position to the right, and a series of subtraction passes are made to develop the next quotient decimal digit.

摘要： A microprogrammed commercial instruction processor in a data processing system includes a bank of switches coupled to a multitapped delay line for selecting delay line signals for setting the basic clock timing. Another of the switches when activated conditions the commercial instruction processor so that when it is reset a special clock setting firmware loop is entered. The loop provides an uninterrupted succession of clock pulses which allows one to adjust the basic clock timing within specification.

摘要： A data processing system includes a commercial instruction processor (CIP) for executing decimal arithmetic instructions. The operands processed by the CIP include packed decimal and string decimal operands. The decimal arithmetic instruction includes descriptors for describing the characteristics of the operands. A register coupled to an arithmetic logic unit stores double words of the operands which are written into the register as double words, bytes or decimal digits. A multiplexer is responsive to control store signals and descriptor signals for generating write control signals which are applied to a read only memory. The read only memory output write signals select the decimal digit, byte or double word positions of the register for writing.

摘要： In a data processing system, a central subsystem includes a plurality of special purpose processing units with one of the processing units serving as a control processing unit within a central subsystem. The processing units are coupled to a common subsystem bus for the transfer of data, control information, and address information within the central subsystem. Access to the subsystem bus is allocated by a bus control unit which also interfaces the central subsystem with other processing units such as a system memory or system I/O devices that are included in the data processing system.
