- 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.
- If on a winter’s night a traveler (Wikipedia)
If on a winter’s night a traveler (Italian: Se una notte d’inverno un viaggiatore) is a 1979 novel by the Italian writer Italo Calvino. The postmodernist narrative, in the form of a frame story, is about the reader trying to read a book called If on a winter’s night a traveler. Each chapter is divided into two sections. The first section of each chapter is in second person, and describes the process the reader goes through to attempt to read the next chapter of the book they are reading. The second half is the first part of a new book that the reader (“you”) finds. The second half is always about something different from the previous ones. The book was published in an English translation by William Weaver in 1981.
