Embedded Computing Design

IoT devices are not actually new. They are just embedded systems mistakenly connected to the Internet. In what follows, I use the term “embedded system” instead of “IoT device” since it is more general.

This is the first part of a four-part series of articles presenting a unique product MPU?Plus? and a methodology for using the Cortex-M Memory Protection Unit (MPU) to achieve improved MCU security.

  The Cortex-M v7 memory protection unit (MPU) is difficult to use, but it is the main means of hardware memory protection available for Cortex-M3, -M4, and -M7 processors[1]. These processors are...

As noted in my previous blog, Security and the Cortex-M MPU, embedded systems are being drawn more into the Internet of Things (IoT), and consequently...

Many embedded systems use no heap. Many of those that do use a heap use a serial heap that must be searched sequentially, and thus can be very slow. M...

Make time for error-handling aids. It'll pay off in the long run. Most RTOSs provide monitoring and reporting of service call and other types of error...

The economics of consumer electronics is driving ever smaller semiconductor feature sizes, also known as "nodes." The node size determines a transisto...

Follow some simple steps and you'll make the right RTOS choice An RTOS consists of a kernel plus middleware. Middleware is needed to do certain functi...

Task switching is important. But don't overdue it. Task switching is what multitasking is all about. However, too much of it may spoil the stew for th...

Embedded systems should be designed the same way that we decorate Christmas trees. The tree is the RTOS, and there are many to choose from. You should...
