Double float read interrupt

bryce johnson

I have a higher interrupt that writes to a double float. Can I be halfway through reading the double float, get interrupted, then read the second half of the double float (which now contains the new data)? Or will it do the full read and then get interrupted?

Thanks

In the assembly I think you would have 2 different LDW instructions, so as a result I believe it is technically possible to experience an interrupt in between the two; however, if they are both in the pipeline at the time of the interrupt the pipeline will run complete, then the branch will occur. So while I believe it is technically possible this should be a pretty small percentage.
