Experience has shown that the portability, speed of development and built-in run-time support (the C Standard Library) of C far outweigh the relatively small cost of using it. As it turns out, much ...

In response to the continuous compromise of networks, multiple countries have begun developing secure platforms and operating systems. Computer companies, university researchers, defense R&D ...

After introducing interrupts and the foreground/background architecture, I am finally ready to tackle the concept of a Real-Time Operating System (RTOS). In this first lesson on RTOS (commonly ...

What if you could strip away the layers of abstraction that operating systems impose and interact directly with your computer’s hardware? Imagine crafting a program where every instruction is executed ...

Modern CPUs can run in two modes: kernel mode and user mode. When a CPU runs in kernel mode, an extended set of instructions is allowed, as is free access to anywhere in memory and device registers.

Traditional semiconductor testing typically involves tests executed by automatic test equipment (ATE). But engineers are beginning to favor an additional late-test pass that tests systems-on-chip ...
