ARM processors are at the core of current mobile computing, embedded systems, and IoT devices. The ARM processor family is vast and is divided into three main core series based on application scenarios and performance requirements: Cortex-A (high-performance application processors), Cortex-R (high real-time processors), and Cortex-M (low-power microcontrollers). The following is a detailed analysis from … Read more
1. Overview In the article “CPU Architecture,” we introduced the three major families of instruction set architectures: <span>x86 family</span>, <span>ARM family</span>, and <span>RISC-V</span>. Did you know that the ARM instruction set also includes three different series: <span>Cortex-A</span>, <span>Cortex-R</span>, and <span>Cortex-M</span>? Are you aware of the differences and relationships between these three series of processor cores? … Read more

Even when using only a single Cortex-A core, the L2 cache cannot be eliminated. Students at the Jingxin Training Camp have asked this question before, and the role of L2 cache is crucial. Why is that? The core issue is that the CPU operates too quickly, while accessing the external main memory is too slow. … Read more
This is a watershed moment; there will be no 32-bit operating systems and no 32-bit applications.” Author | Wu You Arm announced that starting in 2023, all new smartphone CPU cores will be 64-bit only, with no 32-bit compatibility mode. In 2013, Apple introduced the 64-bit A7 processor in the iPhone 5s, marking the beginning … Read more
Last year, Intel and ARM reached a collaboration agreement, where both companies shared their processor manufacturing technologies to accelerate the development of ARM chipsets. Now, the results of this joint effort are about to be revealed, as Intel announced at the ARM Tech Con 2017 conference that the first ARM chip developed in collaboration will … Read more
ARM has introduced a new strategy! Following the Cortex-A35, which is positioned for low-power, low-end smartphones, wearables, and the Internet of Things (IoT), ARM has launched a new CPU core named “Cortex-A32”. This core has lower power consumption and improved energy efficiency, primarily targeting the embedded and IoT markets. The A35 utilizes the ARMv8-A 64-bit … Read more
