Intel and AMD are working on updating the x86 architecture. They plan to introduce the APX (Advanced Performance Extensions) extension. This was reported by Ixbt.com xabar.
This initiative aims to increase processor performance without fundamentally changing the platform.
The main innovation of the APX extension is increasing the number of general-purpose registers in 64-bit mode from 16 to 32. Registers are the fastest data storage level within a processor, and expanding them reduces the number of memory accesses.
APX also includes new types of instructions, including operations that preserve initial data. This reduces redundant copying and facilitates code optimization.
According to developers' estimates, APX will reduce load operations by 10 percent and store operations by up to 20 percent. This not only increases performance but also reduces energy consumption.
An important advantage of the new extension is its backward compatibility with previous programs. Current software will continue to function without changes.
For now, APX is still in the design and simulation phase.
