Multiplication / Division Unit (MDU)
This on-chip arithmetic unit of the C517A provides fast 32-bit division, 16-bit multiplication as well
as shift and normalize features. All operations are unsigned integer operations.
Table 6
describes
the five general operations the MDU is able to perform.
1) 1

CY
= 12
t
CLCL
= 1 machine cycle = 500 ns at 24 MHz oscillator frequency
2) The maximal shift speed is 6 shifts per machine cycle
The MDU consists of seven special function registers (MD0-MD5, ARCON) which are used as
operand, result, and control registers. The three operation phases are shown in
figure 17
.
