"L2$, L3$, I$, D$". Well, OK.
- bee_rider 1y agoHmm?
- daneel_w 1y agoCache is pronounced like cash, which the $ symbol is supposed to allude to.
- bee_rider 1y agoYes, they are obviously caches. I just didn’t understand your comment.
- xxpor 1y agoWow, how have I never put 2 and 2 together on that.
- robinsonb5 1y agoYou're not alone - it took me way longer than it should have done to figure that one out!
- starkruzr 1y agoleading to the unfortunate abbreviation sometimes drawn on blackboards, "$hit"
- grg0 1y agoIt is an apt abbreviation if you visualize shit tightly packed in a container. And when you thrash the cache, shit hit the fan (and spills to VRAM.)
- 0x000xca0xfe 1y agoIt's just shorthand for "level 2 cache", "level 3 cache", "instruction cache" and "data cache".
- daneel_w 1y agoYes, obviously. It's just the first time I've seen a CPU designer/manufacturer use such relaxed "informality" in a spec sheet.
- DiabloD3 1y agoI've been seeing it more and more, especially with vendors that don't speak a western language on their spec sheets. Everyone can tell what L1$ means, but what would L1 缓存 mean?
- Findecanor 1y agoI follow RISC-V and see it all the time. CPU manufacturers also aren't using Unicode, using the letter u instead of µ (micro), and the letter A instead of Å (the unit Ångström).
- jasonwatkinspdx 1y agoThe slides are for Hot Chips, which is a very engineering focused venue. It's not your normal marketing stuff.
- Brian_K_White 1y agoI got it, and hate it. It's approximately like putting an emoticon that looks like money in there. Hey maybe the emoticon can be a pile of gold coins, then it would still be a cache as well as cash.
- bitwize 1y agoOoh, I wonder what strings were put in those BASIC variables...
- daneel_w 1y agoLET L2$="256 KiB"; LET L3$="8 MiB"
