Comparing LCD screens and OLED screens is akin to comparing fuel vehicles with electric vehicles. The acceleration and power levels are simply not on the same scale. The emergence of new technologies inevitably leads to the obsolescence of older ones, often without any warning. Nokia phones are a prime example of this. First, let’s understand … Read more
Overview Integrated circuits are composed of chips (die) cut from silicon wafers (wafer). Each wafer can yield hundreds of chips. ASIC stands for Application Specific Integrated Circuit, which is designed for specific applications, unlike general-purpose memory, microprocessors, etc. There are several types of ASICs: Full-Custom ASIC: This type of ASIC is completely manually designed, without … Read more

Power consumption is a critical performance metric in chips, sometimes even determining the success or failure of a chip. As is well known, the recent “Snapdragon Fire Dragon” incident significantly impacted the market share of this chip. For industrial-grade and automotive-grade chips, the impact of power consumption is not very apparent. However, for consumer-grade chips … Read more
Accurate thermal analysis plays a crucial role in the design of many electronic products, particularly in high-end PCB design. The results of thermal analysis often influence the mechanical layer design of the PCB and the product’s enclosure: whether to install heat sinks, cooling fans, etc. If a cooling fan is installed, it often needs to … Read more
Hello everyone. Let’s assume User A is a smart home developer who needs to choose a low-power processor for home monitoring devices; User B is a gaming smartphone designer who seeks ultra-fast response and high computing power. Their needs are completely different, and thus the conclusion on whether to choose the quad-core Cortex-A55 or A73 … Read more
