. Connect to I/O Devices: Universal Serial Bus (USB), graphics card, Host bus adapter To access the disk: SSD: The SSD packet is plugged into the I/O bus. An SSD package consists of one or more flash chips and a flash translation layer, instead of a mechanical drive in a traditional rotating disk. SSDs consist of semiconductor memory with no moving parts, so the random access time is faster than rotating the disk, consumes less energy, and is more robust. But easy to wear. Different stor

group-linked cacheAs with the direct map cache, group index bits identify groups.2. Row matching and word selection in group-linked cacheMore complex than direct-mapped caches3. Row substitution when missing in group-linked cachefully-connected cacheA fully-connected cache consists of a group (e=c/b) that contains all the high-speed slowdown.Basic structure:1. Group selection in the fully-connected cacheThere's only one group, so it's simple.2. Line matching and word selection in fully-connecte

specific framework is divided into four categories: 1. For OPL (integer and logical Operations), RRMOVL (register-register transfer) and IRMOVL (immediate count-register transfer)2. For RMMOVL and MRMOVL3. For PUSHL and POPL4. For jump, call and RET The summary is that the clock is used to control the updating of the state elements, and the values are propagated by the combinatorial logic. ExperimentAfter you run the make commandTo view the contents of the directory, you can see o
