- Youngs Creek Falls is a collection of small punchbowl waterfalls that carve a narrow gorge into the surrounding rock. It is very accessible and visible from the road. There is one rappel, and an small optional jump. Because of how short the canyon is, it’s a perfect place to visit weekdays after work.
- Reverse engineering ARM1 instruction sequencing, compared with the Z-80 and 6502 (righto.com)
When a computer executes a machine language instruction, it breaks down the instruction into smaller steps that are performed in sequence. For instance, a load instruction might first compute a memory address, then fetch a value from that address, and then store that value in a register. This article describes how the ARM1 processor implements instruction sequencing, performing the right steps in order. I also look briefly at the 6502 and Z-80 microprocessors and the different sequencing techniques they use.
