ARM will allow manufacturers to use their own command systems in processors

In the near future, an important innovation will occur in the field of interaction between ARM and third-party manufacturers of electronic devices. Developers will be able to increase the efficiency of devices based on ARM processors using their own command systems.
The use of standard template algorithms for the processor painfully “hits” the performance of devices, forcing developers to adjust. With the introduction of new rules, developers will be able to achieve increased processor performance without the need for new chips.
Frankly, developers could prescribe their own teams before, but this required a very difficult integration of software components. Now this whole process should be greatly simplified.
The first available to use their own instruction system will be the Cortex-M33 processors.
