Hardware
The new Type-C USB connector is the latest addition to the USB connector standards. It offers reversible plugs, direction independent cables, USB3.1 speeds, and 3A charging in a connector only a little bigger than the USB 2.0 MicroB connector. In order to add these capabilities the plugs and connectors have additional configuration pins to allow devices to negotiate their state. Supporting the configuration channel may seem like a difficult challenge but it can be achieved fairly simply for the basic use cases.Share on Twitter ∙ Share on Facebook

Within the embedded system space, it is very common to find a FPGA at the heart of the system. This is due to the FPGA’s ability to perform several functions in parallel and its deterministic response. Many embedded systems also contain a processor to handle communication, housekeeping, scheduling, and other tasks traditionally performed in software.Share on Twitter ∙ Share on Facebook
An interesting issue that comes up when writing code for the x64 architecture is which code model to use. This probably isn’t a very well-known topic, but if one wants to understand the x64 machine code generated by compilers, it’s educational to be familiar with code models. There are also implications for optimization, for those who really care about performance down to the smallest instruction.Share on Twitter ∙ Share on Facebook
