PROGRAMMING AND NUMERICAL SYSTEM Internal. number system Binary coded decimal Decimal digits/word Variable word and block length Decimal digits/instruction 10 Instructions per word 1 Instructions decoded 20 Arithmetic system Fixed point Instruction type Two address (Source and destination) Number range Alphanumeric: 0 to 99 characters per word for computing up to 12 places Instruction word format +-----+-----+-----+-----+-----+-----+-----+-----+-----+-------+ | V | W | X | Y | Z | D | d | O | P | (sign)| +-----+-----+-----+-----+-----+-----+-----+-----+-----+-------+ ARITHMETIC UNIT Incl Stor Access Exclud Stor Access Microsec Microsec Add 560 186 Mult 3,137 2,577 Div 4,830 4,270 Construction (Arithmetic unit only) Magnetic Cores Arithmetic mode Parallel Timing Synchronous (Excepting File Drums) Operation Sequential and. Concurrent The operation times given above for addition and multiplication are for the number 999,999 as operands. The divide time is for a 5 digit quotient. Computer operations are mainly sequential. Input-output operations are concurrent with computation. The arithmetic unit may also work concurrently with non-arithmetic operations. Non-arithmetic operations may be performed concurrently during the last 113 microseconds of the addition time, during the last 2,265 microseconds of multiplication, and during the last 3,966 microseconds of division. The arithmetic unit consists of the product, multiplier, and multiplicand registers. These registers are 13 digits in length, with character position 0 holding the sign and character position 12 holding the most significant character. Since the system is capable of handling British sterling notation, the adder, which is part of the arithmetic unit, operates in sterling notation if digit d of the addition, subtraction, multiplication, and round instructions is not a zero. In this case, scale of 10 operation is specified. Multiplication is accomplished by halving the multiplier and doubling the multiplicand, with the contents of the multiplicand register being added to the contents of the product register each time the number in the multiplier is odd. On the whole, this method of multiplication is faster than one involving successive additions. Division is accomplished by repeated subtraction of the divisor from the dividend, with the dividend initially in the multiplicand register and the divisor in the multiplier register. The quotient appears in the multiplicand register and the remainder in the product register. STORAGE No. of No. of Access Media Words Digits Microsec Magnetic Core Variable 200 - 10,000 34 Hi-Speed Drum Variable 58,500 11,000 File Drums Variable (1.875-652) x 106 197,000 Magnetic Tape Access times given above include drum switching. The high speed drum rotates at a speed of 100 revolutions per second, recording is performed in parallel and includes 6,000 characters of input-output buffers. The file drum rotates at 3 revolutions per second, recording a serial. Each file drum has a capacity of 15 x 10 bits. Characters may be alphanumeric or numeric only. The magnetic file drum is the bulk storage medium. It is 15 inches in diameter by 15 inches long, having a capacity of 1,875,000 alphanumeric characters or 2,500,000 numeric characters. Any number of these file drums (up to a maximum of 330) can be used in a given installation, and regardless of how many are used, the average random access time to any part of the entire file remains onesixth of a second. For intermediate and buffer storage a single high-speed drum is used, having a capacity of 58,500 alphanumeric characters and an average random access time of 10 milliseconds. Internal working storage (OAST) consists of from 200 to 10,000 characters of magnetic core storage with an average access time of 34 microseconds. In addition, there are twelve transfer registers, each with magnetic core storage for 10 alphanumeric characters. Since the storage capacity of the magnetic file drums and of OAST is scalable, a user need acquire only the capacity required by his application. This factor, together with a choice of the type and quantity of input and output devices, provides a flexible system that can be tailored to the individual requirements of any given application. File drums are grouped into units of from one to 33 drums per unit (actually from 300 to 10,000 tracks per unit, which, at 300 tracks per drum, would be a maximum of 33 1/3 drums per file drum unit.) The maximum number of file drum units in a given installation is 10. Both the number of file drums per unit and the number of units are determined by the requirements of the application for which the system is intended. Each file drum unit contains its own reading and writing mechanism and track selection devices. In locating a record in a file drum unit the computer must first select the proper track by placing the track number in the track address register. The track number may be wholly contained in the record number (tag), or it may be found on an index track which relates record numbers to the appropriate track numbers. Transfers from a file drum unit can be in the form
BRL 1961, DIANA, start page 0229
of a block transfer to OAST, or a word or character transfer to the arithmetic unit or one of the transfer register. Multiple-block transfer to OAST are also possible, provided OAST is large enough. Information can be transferred from one file drum unit to another, a track at a time. If the installation includes a magnetic tape unit, information can also be transferred from a file drum unit to tape, a track at a time. Information can be written on the file drum in only three ways: by a block transfer from OAST, by a track transfer from another file drum unit, or by a track transfer from magnetic tape. During track transfers in either direction, the computer may perform other operations which do not require the use of the drums. The time required for a track transfer is 0.6 second. One drum, therefore, can be loaded or unloaded in three minutes. On the file drums, information is stored in serial by bit fashion. On the magnetic tape it is stored in parallel by bit, serial by character fashion. The high speed drum serves as an intermediate speed general storage for the computer and in addition contains the input-output buffers. This drum sets the system pulse repetition frequency of 150 kc by means of an engraved clock track. A second clock track is used in locating sectors on the drum. This sector clock track has 20 equal divisions which are used to locate the 20 sectors of any given band. The use of bands (adjacent tracks in groups of 7) permits parallel by bit handling of handling of characters and a 150 kc frequency. The capacity of this drum can be specified for each system arrangement. Magnetic Core Storage (OAST, Transfer Registers) OAST has a maximum size of 10,000 characters arranged into 100 sectors of 10 decades per sector, 10 characters per decade. Its minimum size is two sectors or 200 characters. Information is located by sector, decade, and character position, or by sector and word number. Data is handled in parallel by bit, serial by character at a character frequency of 150 kc. The maximum access time to any characters is 9 bit times or 60.3 microseconds (the time required to move from the first to the last character in a decade.) Information recorded in OAST wipes out the previous characters, while that read from OAST is retained in storage by recirculation of the characters. In a single-block transfer to OAST, the most significant character of the block transferred is placed in the zero position of the decade addressed. In a multiple-block transfer to OAST, the most significant character of the first block transferred is placed in the zero position of the decade addressed; following blocks are written densely. The number of blocks to be transferred is specified in the instruction.

Information to be processed or stored can be entered into the system in a number of different ways; via punched paper tape, punched cards, direct keyboard or in certain cases, via magnetic tape. Output can be via punched paper tape, punched cards, line printer, direct typewriter cathode ray tube viewer, or in certain cases, magnetic tape. The magnetic tape input and output units are more in the nature of drum loading and unloading devices; they are used chiefly to store information to which random access is not currently required, or to provide duplicate storage for security purposes.

PRODUCTION RECORD Number produced 1 Number operating 1 The DYSEAC was designed and constructed by the Electronic Computer Laboratory of the National Bureau of Standards as part of a development program under the sponsorship of the Department of Defense. It was delivered to the Signal Corps in May 1954. RELIABILITY, OPERATING EXPERIENCE, AND TIME AVAILABILITY Acceptance test passed in April 1954. ADDITIONAL FEATURES AND REMARKS For further information on this system see Transactions of the IRE-PGEC, Vol. EC-3. No. 1, Mar. 1954. Transactions of the IRE-PGEC, Vol. EC-3, No. 2, June 1954. Journal of the ACM, Vol. 1, No. 2, pp 57-81, April 1954. Proceedings of the IRE, Vol. 41, Oct. 1953, PP 1380-1387. Circular No. 551 National Bureau of Standards, January 1955. Two counter-registers are provided for program sequencing. Each counter holds a twelve-binary-digit address. The coder may select the address in either counter as the address of the next instruction to be performed. Also, either counter-register can furnish the base number for relative addresses. Major design emphasis was placed on versatility of control facilities and on latitude for expansion of the installation. The versatility is achieved by (1) the concurrent input- output property, (2) a self-regulation property which allows the external environment to automatically control the pace of the internal work program, (3) an interruption property which enables the machine to handle unscheduled ,job assignments which originate externally without advance notice and must be executed as soon as possible, and (4) the preceding three properties acting in concert enable the machine to be employed as a control element in a generalized feedback loop.
