Operands:
S
1
: Matrix source device 1 S
2
: Matrix source device 2 n: Matrix length (K1~K256)
D: Pointer Pr; comparison result (bit number)
Explanations:
1. MCMP instruction compares each bit between matrix S
1
and matrix S
2
and stores the bit
number of the comparison result in D. The comparison starts from the next bit of the pointer.
2. The matrix comparison flag (M1088) decides to compare between equivalent values (M1088 =
ON) or different values (M1088 = OFF). When the comparison is completed, it will stop
immediately and M1091= ON to indicate that matched result is found. When the comparison
progresses to the last bit, M1089 = ON to indicate that the comparison has come to the end of
the matrix and the number of the last bit will be stored in D. In next scan cycle, comparison
starts again from the first bit (bit 0), at the same time M1090 = ON to indicate the start of the
comparison. When D (Pr) exceeds the valid range, M1092 = ON to indicate pointer error, and
the instruction will be disabled.
3. The matrix operation requires a 16-bit register for designating a bit among the 16n bits in the
matrix. The register is the Pointer (Pr) of the matrix, designated by the user in the instruction.
The valid range of Pr is 0 ~ 16n -1, corresponding to b0 ~ b16n-1 in the matrix. The value of
pointer should not be modified during the execution of matrix instructions so as to prevent
execution errors.
4. When M1089 and M1091 take place at the same time, both flags will ON..
5. If operands S
1,
S
2,
or D use KnX, KnY, KnM, KnS format, only n = 4 is applicable.
