What is an Embedded-CPU?

After we recently explained the difference between mobile and desktop CPUs, we would now like to go into a third type: the embedded CPUs.

What does "embedded" mean?

An embedded system is a computer that is integrated in a technical environment and takes over tasks such as monitoring, control or data processing. These include, for instance, small computers in washing machines, televisions, routers, refrigerators or cars. However, we are now talking about somewhat larger systems: Embedded PCs that are equipped with a corresponding CPU.

Where are embedded CPUs used?

Embedded CPUs are mainly used in the professional environment, for example for industrial applications, in vehicles or in medical technology.

What are the advantages of an embedded CPU?

The CPUs are characterized by increased reliability, an extended temperature range and above all by a long component availability. For example, Intel guarantees long-term availability of up to 15 years for its embedded processors. The advantage of this: once an application is running, its use is secured for the next few years and the developers do not have to adapt the hardware and software again after a short time. In addition, embedded systems are often certified. If the CPUs are available for many years, there is no need for expensive re-certifications.

Another advantage is that embedded CPUs are extremely robust, since they are usually soldered processors with BGA (Ball Grid Array), which bring a high level of mechanical and thermal robustness with them. This means, that Embedded PCs can run 24/7 in harsh environments without problems. Thanks to their compact design, embedded CPUs are made for Mini-PCs and score with low power consumption.

What are the disadvantages of an embedded CPU?

With all the advantages, the question arises whether an embedded CPU has any negative properties. In fact, we can only mention the low performance here, since, as with mobile CPUs, not much can be accommodated in a small space. However, a lot has happened here in recent years. And it is always enough for the areas in which embedded CPUs are mainly used.

Intel and AMD embedded CPUs

Both major processor manufacturers have various models on offer: Intel has embedded CPUs in the Celeron, Pentium and Core i3 series. AMD offers the Ryzen Embedded and Epyc Embedded series.

What is the difference between mobile and desktop CPUs?

CPUs are not always the same. Depending on the device in which a processor is installed, different characteristics with regard to performance, power consumption or waste heat are important. Which types there are and what distinguishes them, will be clarified in this article.

Industrial PCs part 5: Long-term availability

Ever wondered what would happen if a large project can not be supplied with the required PC systems, already after a short time? Exactly: it would not be that great. In the last part of our blog series about industrial PCs we reveal, why long-term availability is the icing on the cake.
