● A matrix is comprised of 2 or more consecutive 16-bit registers. The number of registers comprising the
matrix is called the matrix length (L). One matrix altogether has L×16 bits (points), and the basic unit of the
object for each operation is bit.
● The matrix instructions treats the 16×L matrix bits as a set of series points( denoted by M
0
to M
16L-1
).
Whether the matrix is formed by register or not, the operation object is the bit not numerical value.
● Matrix instructions are used mostly for discrete status processing such as moving, copying, comparing,
searching, etc, of single point to multipoint (matrix), or multipoint-to-multipoint. These instructions are
convenient, important for application.
● Among the matrix instructions, most instruction need to use a 16-bit register as a pointer to points a specific
point within the matrix. This register is known as the matrix pointer (Pr). Its effective range is 0 to 16L-1,
which corresponds respectively to the bits M
0
to M
16L-1
within the matrix.
● Among the matrix operations, there are shift left/right, rotate left/right operations. We define the movement
toward higher bit is left direction, while the movement toward lower bit is right direction, as shown in the
diagram below.
