Today, we're going to explore Standard ARM cores. ARM licenses these cores to different companies to build customized processors. Can anyone tell me what this licensing model means?
Does it mean that ARM doesn’t make the processors themselves?
Exactly! ARM designs and licenses, which allows many companies to create their own ARM-based chips. This helps ARM to reach diverse markets. Now, we have three main series: Cortex-M, Cortex-A and Cortex-R. Who can tell me what each series generally focuses on?
Cortex-M is for low-power applications, right?
Correct! The Cortex-M series is perfect for embedded systems like sensors. And what about Cortex-A?
That one is for high-performance applications, like smartphones.
Great answer! Now, can anyone explain the purpose of the Cortex-R series?
Cortex-R is used for real-time systems that need reliability, like in cars.
Well done! Remember, M, A, and R can help you recall: M for Microcontrollers, A for Application processors, and R for Real-time systems.
Let's summarize. Standard ARM cores are versatile and cater to various needs: low power, high performance, and real-time operations. Understanding these cores is key to leveraging ARM's technologies effectively.

Now that we know the series, let's dive into some examples starting with the Cortex-M series. Can anyone name a few processors in this series?
I think Cortex-M0 and Cortex-M4 are part of it.
Yes! Cortex-M0 is great for simple tasks, while Cortex-M4 is capable of handling more complex operations. What applications do you think they would be used in?
Cortex-M0 might be in small sensors, and maybe the M4 could be in home automation systems.
Exactly! And now for the Cortex-A series, can anyone provide examples?
Cortex-A53 and Cortex-A78!
Wonderful! These cores are found in high-performance devices. Ask yourselves, why is multitasking important in these devices?
Because they run complex applications like games and videos simultaneously.
Perfect! Finally, let’s talk about the Cortex-R series. Who can name a processor here?
Cortex-R5!
Great! The focus here is on reliability in real-time applications. To summarize, each series serves unique needs—M for low power, A for high performance, and R for real-time reliability.

Let’s contrast what we learned about Standard ARM cores with Custom ARM cores. What do you think are the key differences?
Standard cores are pre-designed by ARM, while custom cores are made by companies to fit their specific needs.
Exactly right! Companies like Apple and Qualcomm create custom cores which may include unique features. Why would a company prefer to use custom designs?
To have specific enhancements that meet their products' requirements!
Yes, and these enhancements could include specialized hardware for graphics or AI. To summarize, Standard ARM cores offer proven designs and flexibility, while Custom ARM cores provide tailored solutions for specialized applications.

Chapter Content
ARM designs the cores and licenses them to other companies for production.
Detailed Explanation
Standard ARM cores are processors designed by ARM itself. Instead of directly manufacturing these cores, ARM licenses the design to various companies. This means that the companies can produce their own chips based on the ARM architecture, allowing for a wide variety of products that leverage ARM's technology and efficiency.
Examples & Analogies
Imagine if a popular recipe book allowed various chefs to create their own dishes based on the same recipe. Each chef might add their unique twist, much like how different companies design chips that use ARM's core designs but modify them slightly to suit their specific needs.
