Multiplier cycle counts
Table 7-3 shows the instruction cycle times from the perspective of the data bus:
The number of cycles that a multiply instruction takes to complete depends on which
instruction it is, and on the value of the multiplier-operand. The multiplier-operand is
the contents of the register specified by bits [8:11] of the ARM multiply instructions, or
bits [2:0] of the Thumb multiply instructions.
•
•
For ARM MUL, MLA, SMULL, SMLAL, and Thumb MUL, m is:
1 if bits [31:8] of the multiplier operand are all zero or one
2 if bits [31:16] of the multiplier operand are all zero or one
3 if bits [31:24] of the multiplier operand are all zero or all one
4 otherwise.
For ARM UMULL, UMLAL, m is:
1 if bits [31:8] of the multiplier operand are all zero
2 if bits [31:16] of the multiplier operand are all zero
3 if bits [31:24] of the multiplier operand are all zero
4 otherwise.
