ARM DDI 0165B
Thumb branch with link
A Thumb Branch with Link (
instructions, and takes four cycles:
1.
2.
Table 8-5 shows the cycle timings of the complete operation.
Cycle
1
2
3
4
The first instruction acts as a simple data operation. It takes a single cycle to add
the PC to the upper part of the offset, and stores the result in r14. If the previous
instruction requested a data memory access, the data is transferred in this cycle.
The second instruction acts similarly to the ARM
a.
b.

During the first cycle, the ARM9E-S calculates the final branch target
address while performing a prefetch from the current PC.
During the second cycle, the ARM9E-S performs a fetch from the branch
destination, while calculating the return address to be stored in r14.
During the third cycle, the ARM9E-S performs a fetch from the destination
+ 2, refilling the instruction pipeline.
