Fully Serialized Pipeline Digital Signal Processing Techniques

Geesh... announcing it before writing anything, again!

Ahem, anyway, it's very related to (one of) the research work that I've been working on for quite a while. This piece of writing is mainly about designing different types (for example, signed and unsigned integer, IEEE float, etc.) of serialized arithmetic cores, which, in this context, means adder and multiplier.

Although being slow and sometimes occupying much more space to implement, serialized logic does show its amazing properties under specific applications. As mentioned in the previous HP calculator articles, serialized logic can be implemented easily with dynamic logic, which translates to a much smaller silicon footprint.

Also, when pipelined, serialized logic can show no less performance than its parallelized counterparts.

To keep it short: I'm still alive and sound, with just one little problem: my daily routine is completely crushed by great pressure and many other sorts of internal troubles; it's high time I recover.

HP35: A Bit-Serial Wonder - 3. LED Magic

Part3. LED Magic

LED numeric display is the icon of HP classics. With just a single 5-bit register inserted, how could they design such a full-featured, flicker-free and properly PWM'd display that has 15 digits?

Sorry for such a long quiescence. Originally I was planning to actually make a board that drives the LED display before writing anything. Unfortunately, since quarter a year ago, I'm completely occupied by all sorts of things, and the plan is delayed forever. I'll try if I'm free at some point in the future.

This is the first article written in the new "Gutenberg" WordPress editor. Noice!
