Continuing from the previous article on ARMV8-A MMU – Part 1. IPS[34:32] (Intermediate Physical Address Size) controls the size of the IPA address space. When IPS=000, it indicates a 32-bit address space; when IPS=101, it indicates a 48-bit address space. The meanings of other values can be referenced in the ARMv8 documentation. After setting the … Read more
Continuing from the previous article on Introduction to MMU in ARMV8-A – Part 2. This article will continue from the last section and explain the multi-level page tables of MMU. The previous section discussed an example of a single-level page table, while this section will discuss an example of a two-level page table. Below is … Read more

Arm is known for its Cortex series processors in mobile devices, but the mainstream Cortex-A series CPUs are not the only CPUs offered by the company. Arm also provides the Cortex-R series “real-time” processors for high-performance real-time applications. The last time we discussed the Cortex-R products was with the R8 released in 2016, when the … Read more
About ARM Cortex The ARM Cortex series is divided into three categories: Cortex-A, Cortex-R, and Cortex-M. Among them, processors based on Cortex-A are suitable for running systems with extremely high performance requirements. If high performance is required while ensuring real-time capabilities, it is suitable to use Cortex-R architecture chips. Cortex-M is suitable for other applications … Read more
