Good news. ARM's CCA [1] seems revolutionary in comparison.

From Wikipedia:

>Transactional Synchronization Extensions (TSX), also called Transactional Synchronization Extensions New Instructions (TSX-NI), is an extension to the x86 instruction set architecture (ISA) that adds hardware transactional memory support, speeding up execution of multi-threaded software through lock elision.

How is that related to CCA, which seems to be a security feature?

CCA seems more like SGX than TSX
