I don't really agree. What is labelled a "CISC instruction set" here would more usually just be called a control interface. But maybe I'm missing some sort of context here. (Contrasting it with "ZISC" for marke

So? Samsung also sells a lot more smartphones than Apple, yet Apple makes far more profit from them. You can't pay R&D with revenue. There are probably more PowerPC chips sold via laser printers and such than x86 chips. Conversely,

It's almost always better to have a dedicated chip implement some algorithm, if it makes economic sense to do so. From hard drive controllers to Google's TPU.

Regarding single-threaded performance it just seems increasingly likely that we finally hit the wall of what the current technology is able to support. I don't expect major advances here until other manufacturing tech is used.

Because your course is based on outdated materials. In the 80s and 90s academia and high-end computing was taken by a RISC illusion. RISC architectures were simple and clean and easy to implement at higher performance than any CISC processo

Prediction: RISC-V will at best take on in some niche markets. If RISC-V is lucky, it will maybe displace MIPS. -- Usual P.S.: The ISA has become less and less relevant to processor performance since the mid 90s (when Intel and AMD introduc

Tape storage normally uses either an index (linear FS or off-tape, e.g. for object storage) or a more-or-less recoverable stream format ("tar").

That's the difference between bad API design and good API design. strncpy is bad. But so are many APIs that originated in a time where arrays were zero-indexed to save one or two instructions in a compiler. (Though these are a bit youn

That it's difficult to accurately define "what the application thought it wrote" when considering corruption at various abstraction layers; somewhat similar to calculating checksums over already corrupted data.

In lesser languages this tends to translate to "you need to deal with code using bizarre pre-processor coding and/or external code generators". glib*-stuff is a neat example for the former (although a lot of it's code an

That's actually not using the bridge as an instrument... the little boxes measure how you pull on the wire and send that data to a synthesizer. That's why it sounds so diverse.
