Parallelism between CPU and FPU

Matic over 9 years ago

Hi.

I have a question regarding Cortex-M4 processor with floating point unit. Is it somehow possible to do some computation in parallel in CPU (with integers) and FPU (with floats)?

Probably not, because both units need their own instructions to perform a math operation and the instructions can only be executed sequentially one after another.

Any thoughts on that?

Thanks

No. It does one operation at a time. The operations are quite quick though if you look at the technical reference manual.
The Cortex-M7 is dual-issue and can do the sort of thing you say
