Operands:
S: Matrix source device D: Operation result n: Matrix length (K1~K256)
Explanations:
1. MBS instruction shifts the bits in the matrix to the left or the right. M1097 = OFF, bits shift to
the left, M1097 = ON, bits shift to the right. The empty bit (left shift: b0; right shift: b16n-1)
after every bit is shifted once will be filled with the value of M1096 (Borrow flag for matrix
operation). The bit which is shifted out of the matrix (left shift: b16n-1; right shift: b0) will be
sent to M1095 (Carry flag for matrix operation) and operation result is stored in D.
2. The pulse execution instruction (MBSP) is generally adopted.
3. If operands S or D use KnX, KnY, KnM, KnS format, only n = 4 is applicable
4. Associated flags:
M1095: Carry flag for matrix rotation/shift/output
M1096: Borrow flag for matrix rotation/shift/input
M1097: Direction flag for matrix rotation/shift
Program Example 1:
When X0 = ON, M1097 = OFF, indicating a left matrix shift is performed. Assume matrix borrow
flag M1096 = OFF (0) and the 16-bit registers D0 ~ D2 will perform a left matrix shift and the result
will be stored in the matrix of the 16-bit registers D20 ~ D22, meanwhile the matrix carry flag
M1095 will be ON (1). .
