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

)
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;
The number of bits in a:
‘fixed point addition instruction (niax)—
fixed point multiplication instruction (nimx)—
floating point addition instruction (niaf)—
floating point multiplication instruction (niaf)—
is the appropriate shortest single fixed or floating point instruction length which permits full direct addressing of the main storage;
NOTE:
1. When multiple instructions are required to simulate an appropriate single instruction, the number of bits in the above instructions shall be taken to be 16 bits plus the number of bits (biax, bimx, bviaf, bimf) which permits full direct addressing of the main storage.
(Thus
niax = 16 + biax;
nimx = 16 + bimx;
niaf = 16 + biaf;
nimf = 16 + bimf;
2. 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;
The number of bits in a fixed point operand (nox) is
(a) the shorted fixed point operand length; or
whichever is greater;
The number of bits in a floating point operand (nox) is
(a) the shortest floating point operand length; or
whichever is greater;

(b) if only the maximum and minimum execution times of the instructions are published, the sum of:
(1) the maximum execution time of an instruction (tmax); and
(2) twice the minimum execution time of this instruction (tmin); divided by three
(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;
(d) if the longest fixed point operand length is smaller than 16-bit, the time required for the fastest available subroutine to simulate a 16 bit fixed point operation;
NOTES:
1. If the addressing capability of an instruction is expanded by using a base register, then the execution time shall include the time for adding the content of the base register to the address part of the instruction.
2. When calculating processing data rate for computers with cache sizes smaller than 64K Bytes, the execution time of the appropriate instructions will be calculated as follows:
The cache hit rate being:
1.00 for cache size of 64k Byte
0.95 for cache size of 32k Byte
0.90 for cache size of 16k Byte
0.85 for cache size of 8K Byte

(i) the input/output control unit transfer rate (Rtc); or
(ii) the sum of the individual transfer rates of all independent seek mechanisms (Rts);
(Thus: Rtd = min (Rtc; SUM Rts)
(1) of an input/output control unit (Rtc):
(i) with rotational position sensing (rps), is the product of:
(a) the number of independent read/write channels (C); and
