CP Normalize Instructions
Read central memory at

X j ,
Xk
This instruction loads into Xj the word at location (Xk), where Xk is a
right-justified 21-bit relative word address. Bits 21 through 59
of
Xk are
ignored. I f the 21 bits of
Xk are greater than or equal to FLC, an
address-out-of-range condition is detected.

Xk
[is instruction stores Xj in location (Xk), where Xk is a 21- *bit relative w o r t
address. Bits 21 through-59 of Xk
are ignored. If the 21 bits of Xk are
greater than or equal to FLC, an address-out-of-range condition is detected.
CP Normalize lnstructions
The normalize instructions (table 4-12) perform normalizing operations in
floating-point format and deliver the normalized result to Xi.
