What is machine learning?
Machine learning, as a type of Artificial Intelligence, is typically used to create models with which to analyze data. Machine learning is a programming process whereby instead of coding a program as with traditional computer architectures, the computer is fed from dozens to thousands of sample data sets that demonstrate what will and will not […]
Writing Efficient C code for Embedded Systems: The cost of unnatural data sizes
Different architectures have different “natural” data sizes. Most MCUs have the same CPU width as data bus width, which makes sense. Some MCUs might have memory that is not consistent with their available data bus width, however. In other words, for some MCUs, there can be a difference between the CPU’s “natural” word length and […]
8-bit MCUs carry up to 8 kB of Flash in low pin-count packages
Microchip Technology Inc. has released a new generation of 8-bit tinyAVR MCUs. The four new devices range from 14 to 24 pins and 4 KB to 8 KB of Flash and are the first tinyAVR microcontrollers to feature Core Independent Peripherals (CIPs). The new devices will be supported by START, an innovative online tool for intuitive, […]
Avoiding stack overflow in embedded processors
A stack is like a special buffer, or working memory, where processes are tracked. The stack is where processes or tasks “keep notes” on what they need to do the next time the processor becomes available. The stack works “last in, first out,” and tracks local variables as they get pushed onto and popped off […]
VPX3 SBC supports safety certified RTOS
Curtiss-Wright’s Defense Solutions division today announced that it is collaborating with Green Hills Software to support the RTCA/DO-178C certified multi-core INTEGRITY-178 tuMP (Time-Variant Unified Multi Processing) real-time operating system (RTOS) on its safety certifiable COTS single board computers (SBC). The first Curtiss-Wright product to support Green Hills Software’s safety certified multi-core RTOS is the recently […]
