Inside the Internet of Things - Bryon Moyer Blog
[From the last episode: we looked at the differences between computing at the edge and in the cloud.] We’ve looked at the differences between MCUs and SoCs, but the one major thing that they have in common is that they have a CPU. Now… anyone can define their own CPU […]

[From the last episode: We saw how we can combine computing components together on a single chip.] We’ve looked at a number of basic computing notions, and we’ve seen how, more or less, these come together in computing systems. Now let’s put them into the context of IoT systems. Where […]

[From the last episode: We looked at a basic computing system.] So far, we’ve seen that a computing system has to consist, at least, of a processor and some memory. And we’ve seen that there are different kinds of memories with different properties, and we may need some of all […]

[From the last episode: We looked at the role of cache memory in a processor.] Now that we’ve looked at the major components of a computing system, let’s put them together. We won’t talk about how we’re putting them together for the moment; that comes next. We’ll start with the […]

[From the last episode: We looked at subroutines in computer programs.] We saw a couple weeks ago that some memories are big, but slow (flash memory). Others are fast, but not so big – and they’re energy-hungry to boot (SRAM). This sets up an interesting problem. When the processor needs […]
