    摘要: Apparatus for encoding multi-digit binary-coded-decimal numbers of a predetermined quantity of bits, for example, of at least two decimal digits, into a re-expressed lower number of bits, the binary-coded-decimal number being expressed in the form (abcd) (efgh). An encoder selects a set from a class of sets of bit symbols with each set corresponding to a respective combination of the bits in the most significant position, (a) and (e), of each of the four-bit groups representing the respective digits of the binary-coded-decimal number to be encoded. The selected set is the set which corresponds to the respective combination and the encoder determines certain of the bits of the multi-digit binary-coded-decimal number to be encoded and leaves undetermined the remaining bits of the number. The encoder is connected to register means having a plurality of bit positions which are equal to the quantity of bits less than the predetermined quantity, and stores not only the determined bit symbols but also the undetermined other bits of the multi-digit binary-codeddecimal number.

    摘要: This translator is capable of receiving and automatically displaying most significant digit first, a number to any numerical base or radix; and it may then convert the number to another base and display the converted number, or it may store the number for use in an arithmetic operation. The translator keyboard includes a plurality of radix keys, and before a number is entered, its corresponding radix key is pushed to route the input data (number) to one of a plurality of holding registers, and simultaneously to a display register. When a number has been entered, it may be converted to another base and displayed, merely by pushing a different radix key. Alternatively the number can be stored by pushing a storage key, after which a second number is entered and an arithmetic unit may be operated to add, subtract, multiply or divide the two numbers.

    摘要: A circuit arrangement, for converting a decimal number expressed in the BCD code into a pure binary number, comprises plural binary full adder circuits arranged successively in ascending binary digit order and each having signal inputs and binary digit outputs. Plural BCD code input terminals have applied thereto the decimal number to be converted, and lines connect each code input terminal commonly to all those signal inputs of the adder circuits which are associated, in correct decimal column position, with those 2n numbers which yield, as their sum, the decimal number, expressed in the BCD code, and indicated, with consideration of its decimal column position, at their respective code input terminals. The adder circuits are interconnected in such a manner that the carryover and output signals of each binary full adder circuit are supplied in correct decimal column position to the signal inputs of the respective succeeding binary full adder circuit.

    摘要: A high-speed binary-to-binary coded decimal converter which includes a plurality of decades connected in cascade. Interposed between each of said decades is a carry circuit. The carry circuit supplies carry numbers to the succeeding decade, plus it sends a corrector number back to a corrector circuit associated with the preceding decade. This corrector number is combined with binary numbers already stored in the corrector circuit to produce a proper signal on a readout device associated therewith.

    摘要: Data processing apparatus for shifting a binary signal coded in a first number base by digits coded in a second number base. A first register stores an operator identifying a shift. A second register stores a scale factor signal identifying the number of required digit shifts. Data processing apparatus is responsive to the stored shift operator and the stored scale factor for shifting the binary signal coded in the first number base by the number of digits in the second number base identified by the stored scale factor.
