Operands:
S: Matrix source device D: Operation result n: Matrix length (K1~K256)
Explanations:
1. MINV instruction performs inverse operation on matrix source device S with matrix length n
and stores the result in D.
2. If operands S
,
D use KnX, KnY, KnM, KnS format, only n = 4 is applicable.
Program Example:
When X0 = ON, MINV performs inverse operation on 16-bit registers D0~D2. The operation result
is then stored in 16-bit registers D20~D22
