As automotive electronic control systems gradually develop towards centralization, the complexity of software is constantly increasing. Chips, as the core carrier of electrification and intelligence in vehicles, are becoming increasingly important. For autonomous driving systems, the implementation of technology relies on the real-time processing of a large amount of sensor data, requiring deep learning and … Read more
Currently, there are two types of civilizations in the world: one is the carbon-based civilization composed of human society, and the other is the silicon-based civilization composed of various chips—because almost all chips are made from single crystal silicon, and the total number of chip systems is several dozen to hundreds of times more than … Read more
Recently, NVIDIA released the "Grace" CPU based on the Arm architecture, attracting considerable attention from peers in the hard technology field. This CPU and server architecture, designed specifically for accelerated computing, can provide up to 10 times the performance compared to the latest NVIDIA DGX systems based on x86 CPUs when combined with NVIDIA's GPUs. … Read more

We all know that for mobile processors, the core of their performance lies in the CPU architecture and GPU cores. For example, ARM Cortex A76 is inherently stronger than A75, while Cortex A55 is certainly better than A53. In terms of GPU, Mali-G73MP6 (where the suffix “MP+x” indicates the number of compute cores) outperforms Mali-G72MP6, … Read more
1. Address Space 1.1 Accessing Registers in ARM How do you access registers in ARM? Just like accessing memory: how to access a register? Use a pointer: int a; unsigned int *p = &a; // p equals "address of a" *p = val; // Writing to this address means writing to a val = *p; … Read more
