What Wonders Will ARM in FPGA’s Clothing Perform? – Zynq

What Wonders Will ARM in FPGA's Clothing Perform? - Zynq

The term Zynq easily brings to mind zinc, the most common chemical element found in batteries, solar screens, alloys, and pharmaceuticals. Zinc can enhance functionality when alloyed with other metals, displaying various colors depending on the alloy's composition. The most common use of zinc is electroplating. So, what is the connection between this name and electroplating? In April 2010, at the Embedded Systems Conference in Silicon Valley, Xilinx released the architecture

Choosing the Right Development Board for Beginners: Is 99 Enough?

For beginners in development boards, my purchasing suggestion is within 100.

This price range can be described as a big battle scene; at this price, you can buy an MCU or a proper development board that can run Linux and Android systems.

I believe this price range actually requires both usable hardware specifications and a software ecosystem.

For those who want to get started with development boards but don't know what they are and want to try them out, I recommend choosing development

Remembering Jim Ready, the Father of Embedded Linux!

On Christmas Eve 2017, my old friend Andre Kobel wrote to me with some unfortunate news that Jim Ready had passed away. He knew I was visiting the US at the time and asked if my schedule would allow me to attend the memorial service. This news was truly shocking! I had seen Jim at the end of 2016 and presented him with my new book, "Chronicles of Embedded Operating Systems,"

Understanding Interrupts in ARM Cortex-A9

1. Concept of Interrupts

In operating systems, interrupts are a crucial component. When certain unexpected situations require host intervention, the machine can automatically stop the currently running program and switch to a program that handles the new situation. After processing, it returns to the original paused program to continue running.

With an interrupt system, polling for events can be avoided, which improves system efficiency.

Typically, in a system, interrupt control is divided into three parts: modules, interrupt controllers, and processors.

The module usually controls
