Intel is developing a new architecture 'x86S' that truncated 32-bit support
Intel has revealed that it is developing a new CPU architecture ' x86S '. Support for 32-bit has been abolished in x86S, and speedup is expected by omitting useless processing.
Envisioning a Simplified Intel Architecture for the Future
In the early 2000s, operating systems and applications were developed to run in a 32-bit environment. After that, in 2003 AMD released the 64-bit compatible CPU ' Opteron series ', and in 2004 Intel also started shipping 64-bit compatible CPUs. Since 64-bit compatible CPUs have been on the market, 64-bit support has progressed rapidly, and at the time of writing, most OSes and applications were developed with 64-bit operation in mind. In addition, in response to the progress of 64-bit support, Windows 11 now includes ``installing a 64-bit processor'' in the system requirements , and the movement to truncate 32-bit support is progressing. .
Intel and AMD 64-bit architectures also support 32-bit operation for backward compatibility. For this reason, even at the time of article creation when 64-bit support has progressed, confirmation processing of 'how many bits to execute processing' is performed before executing calculation processing, which is a hindrance to speed and efficiency. was
According to Intel, with the advancement of 64-bit support for OS and applications, it has reached the stage where it can be considered that 'Is it possible to remove the'rarely used elements' of the 64-bit architecture?' In order to realize this idea, Intel is beginning to consider developing a new architecture that completely eliminates 32-bit support.
Intel calls the architecture under consideration 'x86S' and has also published a 46-page document on x86s. The document is available for anyone to download for free by clicking 'Download PDF' on the public page.
