(3)0.55 times the number of bits in a fixed point operand (nox);

  • divided by the sum of:

(1)0.85 times the execution time for a fixed point addition (tax); and

(2)0.15 times the execution time for a fixed point multiplication (tmx) or for the fastest available subroutine (tmsub) to simulate a fixed point multiplication instruction if no fixed point multiplication instructions are implemented.

Thus:

or If no fixed point multiplication instructions are implemented (tmxequals; tmsub):

If a "digital computer" has neither fixed point addition nor fixed point multiplication instructions, then its fixed point processing data rate is equal to zero.

"number of bits in a fixed point addition instruction (niax), fixed point multiplication instruction (nimx), floating point addition instruction (niaf), or floating point multiplication instruction (nimf) is the appropriate shortest single fixed or floating point instruction length which permits full direct addressing of the main storage. It should be noted that when multiple instructions are required to simulate an appropriate single instruction, the number of bits in the above instructions is defined as 16 bit plus the number of bits (biax, bimx, biaf, bimf) which permits full direct addressing of the main storage;"

"number of bits in a fixed point operand" (nox) is the shortest fixed point operand length, or 16 bit, whichever is greater.

"number of bits in a floating point operand" (no) is the shortest floating point operand length or 30 bit, whichever is greater. If the addressing capability of an instruction is expanded by using a base register, then the number of bits in an instruction, fixed or floating point, addition or multiplication is the number of bits in the instruction with the standard address length including the number of bits necessary to use the base register.

"execution time" is

(a)the time certified or published by the manufacturer for the execution of the fastest appropriate instruction, under the following conditions-“

(1)no indexing or indirect operations are included;

(2)the instruction is in the most immediate storage;

(3)one operand is in the accumulator or in a location of the most immediate storage, which is acting as the accumulator;

(4)the second operand is in the most immediate storage; and

(5)the result is left in the accumulator or the same location in the most immediate storage, which is acting as the accumulator;

(b)if only the maximum and minimum execution times of the instructions are published, the sum of:

  • the maximum execution time of an instruction (tmax), and twice the minimum execution time of this instruction (tmin); divided by three.

Thus:
(t stands for any of the values tax, taf, tmx or tmf);

(c)for central processing units which simultaneously fetch more than one instruction from one storage location, the average of the execution times when executing instructions fetched from all possible locations within the stored word. If the longest fixed point operand length is smaller than 16 bit, execution time is taken as the time required for the fastest available subroutine to simulate a 16 bit fixed point operation. If the addressing capability of an instruction is expanded by using a base register, then the execution time includes the time for adding the content of the base register to the address part of the instruction;

"total transfer rate"-“

(a)of the input/output control unit -“ drum, disc or cartridge-type streamer tape drive combinations (Rtdtot) means the sum of the individual "transfer rates" of all input/output control unit -“ drum, disc or cartridge-type streamer tape drive combinations (Rtd) provided with the system which can be sustained simultaneously assuming the configuration of equipment which would maximise this sum of rates. Thus:

Rtdot = SUMRtd;

"transfer rate"-“

(i)of an input/output control unit -“ drum or disc drive combination (Rtd), is the smaller of either the input/output control unit transfer rate (Rtc), or the sum of the individual transfer rates of all independent seek mechanisms (Rts).Thus:

Rtd = min(Rtc; SUMRts)

(ii)of an input/output control unit -“ cartridge-type streamer tape drive combination (Rtc) is

(a)with rotational position sensing (rps), the product of the number of independent read/write channels (C) and the greatest "maximum bit transfer rate" (Rtsmaxmax) of all independent seek mechanisms; or

(b)without rotational position sensing (rps), two-thirds of this product. Thus:

Rtc = C Γ— Rtsmaxmax (with rps);

or

(iii)

of an independent seek mechanism (Rts) is the product of:

the maximum bit transfer rate (Rtsmax), and the rotational period (tr);

divided by the sum of:

the rotational period (tr), the minimum seek time (tsmin); and the latency time (t1).Thus:

(b)of the input/output control unit -“ magnetic tape drive combinations (Rtttot) is the sum of the individual transfer rates of all input/output control unit -“ magnetic tape drive combinations (Rtt) provided with the system which can be sustained simultaneously assuming the configuration of equipment which would maximise this sum of rates.

Thus:

Rtttot = SUMRttt

  • "transfer rate" of an input/output control unit -“ cartridge-type streamer or magnetic tape drive combination (Rtt) is the product of the number of independent read/write channels (C) the and greatest maximum bit transfer rate (Rttmaxmax) of all tape drives.

  • Thus:

    Rtt = C Γ— Rttmaxmax

(c)of the input/output or communication control unit -“ directly connected data channel combinations, is the sum of the individual transfer rates of all data channels provided with the system which can be sustained simultaneously assuming the configuration of equipment which would maximise this sum of rates;

"transfer rate of any data channel" means the sum of the individual bit transfer rates of all the other peripheral devices, excluding terminal devices, which can be sustained simultaneously on the data channel;

"user-accessible microprogrammability" means the facility allowing a user to insert, modify or replace microprogrammes;

"user-accessible programmability" means the facility allowing a user to insert, modify or replace a programme by means other than a physical change in wiring or interconnections or the setting of function controls including entry of parameters; and

"virtual storage" means the storage space that may be regarded as addressable main storage by the user of a computer system in which virtual addresses are mapped into real addresses. (The size of virtual storage is limited by the addressing scheme of the computer system and not by the actual number of main storage locations.)

"wide area network" means a data communciation system which allows an arbitrary number of independent data devices to communicate with each other; may include local area networks; and is designed to interconnect graphically dispersed facilities.
