Hand-rolled, kettle-boiled, baked to perfection. Worth every minute at the bakery.
Summary
The author discusses their experience building interfaces between hardware designs and external peripherals after completing CPU, bus interconnect, DMA, and memory controller work. They introduce the topic of generating device clocks for peripherals, noting that modern high-speed peripheral design involves two key topics that need discussion.
Key quotes
· 3 pulledAfter building a CPU, utilities for handling bus interconnects, several DMAs and memory controllers, I often find my time focused on building interfaces between designs and external peripherals.
Often, these peripherals require a clock output, coming from the design, and so I'd like to spend some time describing how to generate such a 'device' clock.
There's actually two topics that need to be discussed when working with modern high speed peripheral design.
