Cortex-M7 load instruction latency and pairing

Antti

Hello,

What is the latency for the LDR instruction when the result is used for integer arithmetic operations (for example DSP MAC instructions)?

Also, can 64-bit loads (LDRD) be paired with another instruction? Can I do for example a 64-bit load and an integer MAC at the same time?

I hope ARM will add the latencies and more detailed pairing information to the reference manual soon.
