Logical product of (Xj) and (Xk) to Xi BXi Xj
*
Xk
This instruction reads operands from two X registers, operates on them to form
a result, and delivers this result to a third X register. The operands for
this instruction are in Xj and Xk. The result delivered to Xi is the bit-by-
bit logical product of the two operands. Each of the 60 bits in Xj is compared
with the corresponding bit in Xk to form a single bit in Xi.
A
sample
computation is listed in octal notation to illustrate the operation performed
and includes the four possible bit combinations that may occur.
This instruction extracts portions of a 60-bit word during data processing.

Xj
This instruction reads operands from two X registers, operates on them to form
a result, and delivers this result to a
third X register. The operands for
this instruction are in Xj and
Xk.
The result delivered to Xi is the bit-by-
bit logical product of the value in Xj and the complement of the value in Xk.
Each of the 60 bits in Xj is compared with the corresponding bit in Xk to form
a single bit in Xi.
