Three Ways MCUs Use NAND Flash to Save Boot Code and Firmware

Maybe it’s an application, maybe it’s a time-to-market constraint, maybe it’s just sloppy, but code artisans seem to need more and more programs, data, and scratchpad memory for simple and complex functions. In some cases, this is understandable. GPS requires a lot of map data, which takes up NOVRAM space. In other cases, however, it […]

Introduction to Design Method of One Different and Two Wide in SpinalHDL

In SpinalHDL, Stream can be seen everywhere in its lib library, and in common logic design, especially in the processing of interfaces, the processing of handshake signals is also a common topic. In the acceptance design, the “one width and two widths” design method in SpinalHDL really makes me agree. 》》Stream Stream is essentially a […]

Talk about the precision of floating point numbers

In the process of reviewing the code recently, I saw that my colleague directly used the equality of floating-point numbers as a condition in the code. When other colleagues reminded him, he was still confused and didn’t know why, so there is today’s article. 1. Uneven floating point data We often talk about the precision […]

Calculating the lifespan of SSDs in embedded medical device applications

SSDs have developed into a viable alternative to spinning hard disk drives (HDDs) in many embedded systems, including medical devices. This is because SSDs eliminate the moving parts of HDDs, the largest single-failure mechanism in most medical systems. Medical devices have long product testing and certification cycles and go through a rigorous regulatory approval process. […]
