length of the array (n). A matrix contains 16 × n bits (points) and there is only 1 bit (point) offered for an
operand at a time.
b) The matrix instruction gathers a series of 16 × n bits (b
0
~ b
16n-1
) and designates a single point for operation.
The point will not be seen as a value.
c) The matrix instruction processes the moving, copying, comparing and searching of one-to-many or
many-to-many matrix status, which is a very handy and important application instruction.
d) The matrix operation will need a 16-bit register to designate a point among the 16n points in the matrix for the
operation. The register is the Pointer (Pr) of the matrix, designated by the user in the instruction. The vaild
range of Pr is 0 ~ 16n -1, corresponding to b0 ~ b16n-1 in the matrix.
e) There are left displacement, right displacement and rotation in a matrix operation. The bit number decreases
from left to right (see the figure below).

f) The matrix width (C) is fixed at 16 bits.
g) Pr: matrix pointer. E.g. if Pr is 15, the designated point will be b15.
h) Array length (R) is n: n = 1 ~ 256.
Example: The matrix is composed of D0, n = 3; D0 = HAAAA, D1 = H5555, D2 = HAAFF
