C509-L
Multiplication / Division Unit (MDU)
This on-chip arithmetic unit of the C509-L provides fast 32-bit division, 16-bit multiplication as well
as shift and normalize features. All operations are unsigned integer operations.
Table 8
describes
the five general operations the MDU is able to perform.
1) 1
t
CY
= 6
CLP = 1 machine cycle = 375 ns at 16-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 24
.
