Inside the digital clock from a Soyuz spacecraft

We recently obtained a clock that flew on a Soyuz space mission.1 The clock, manufactured in 1984, contains over 100 integrated circuits on ten circuit boards. Why is the clock so complicated? In this blog post, I examine the clock’s circuitry and explain why so many chips were needed.

RSD RISC-V Out-of-Order Superscalar Processor

RSD is a 32-bit RISC-V out-of-order superscalar processor core. RSD is very fast due to aggressive OoO features, while it is very compact and can be synthesized for small FPGAs. The key features of RSD are as follows: Install the following software for running simulation.

Looking inside a 1970s PROM chip that stores data in microscopic fuses

The MMI 5300 was a memory chip from the early 1970s, storing 1024 bits in tiny fuses.1 Unlike regular RAM chips, this was a PROM (Programmable Read-Only Memory); you programmed it once by blowing fuses and then it held that data permanently.
