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
ARM’s design is the foundation of most mobile device processors worldwide.

This is not an ordinary release; if there is anything different, it is that what Apple did today is something that has not happened in 15 years: the beginning of a CPU architecture transformation … Read more
First, the term ’embedded’ is a concept without a precise definition, as each book offers its interpretation. However, the main idea is the same: compared to general systems like PCs, embedded systems are specialized systems with a streamlined structure, retaining only the necessary hardware and software while discarding the unnecessary parts. Therefore, embedded systems generally … Read more
