noncommutative multiplication? what the hell were they doing?
- dnautics 5y agoMy guess is they were chunking the multiplier cascade and handling using parallel circuits so that the waveform could be independent across the chunks and not be dependent? Edit: found it. 2240004 3-24 C (you will want to search by this key, it's a long document!) http://ed-thelen.org/comp-hist/CRAY-1-HardRefMan/CRAY-1-HRM.html http://ed-thelen.org/comp-hist/CRAY-1-HardRefMan/CRAY-1-HRM.... "Note that reversing the multiplier and multiplicand operands could cause slightly different results, that is, A x B is not necessarily the same as [B] x A"
