Microsoft announced ARM64EC. It’s an ABI for ARM64 that is similar to x64. They say it allows mixing x64 and ARM64 DLLs in the same process.

Cool - perhaps that opens the way for a x64+ARM big.LITTLE processor, with a few hot fast x64 AMD cores (big) and a lot of slow efficient ARM cores (little).

I think it's not related. If you need to run ARM code on performance x64 core, ARM to x84 emulator is needed.

I believe this is for make applications like DAW (that often uses native plugins, some aren't updated well) port to ARM.
