Intel documentation mistake for single floating point precision ! (Nope oops lol) Nope, it's not a mistake... I made a mistake... 8000*8000 is way over 24 bits ! ;) :) I checked with this calculator: http://www.h-schmidt.net/FloatApplet/IEEE754.html And also by doing (2^24) ^ 0.5 = 4096 So: (4095 * 4095)-1 is still in range ! ;) Bye, Skybuck =D ... 2 Feb 2010 14:34
Intel documentation mistake for single floating point precision ! Intel document: " The IA-32 Intel Architecture Software Developer's Manual, Volume 1, Basic Architecture, Document Number 253665 rev 19.pdf" Contains a serious mistake on page 4-5: " Table 4-2. Length, Precision, and Range of Floating-Point Data Types " It reads: " Single precision: 24 bits " ... 2 Feb 2010 14:34
Predicted critical block NUCA Given that L2 (and farther) reads are usually transmitted in about four transfers (e.g., 64B blocks-->four 16B transfers), would it be profitable to place the predicted critical block in a nearby (lower latency) area? (Even a predictor as simple as first read on previous access might provide some benefit--at the c... 2 Feb 2010 14:34
Ignorant TSV questions Would it be useful to make holes through the wafer before metalization, then fill the holes, then add the metal layers, then remove the replace the fill material with metal? Would it be sensible to concentrate on die edges where greater 'slack' is available for wafer-level processing (given the separation of dies... 21 Feb 2010 19:23
