As several people have pointed out, my recent article <47800@sgi.sgi.com> had a couple of typos and a`bug in it. Consider this a retraction/correction: First, when I said ANSI X3T9.3 HPPI-PH was either 125MB/s or 250MB/s, that was a typo. I have had the bit->baud expansion of 4b/5b coding on the brain lately, so for some stupid reason I multiplied the correct numbers by 1.25 when posting! The data rate of HPPI is of course 100 or 200 MB/s (800 or 1600 Mb/s), depending on whether you have a 32 or 64 bit data path, respectively. (It's a 25MHz word rate in either case.) And when I attributed the trademark "HSC" to Cray, I was confused. HPPI was modelled after Cray HSX, to be sure, but "HSC" is a *DEC* trademark. I apologize for the inaccuracies. -Rob ----- Rob Warnock, MS-9U/510 rpw3@sgi.com rpw3@pei.com Silicon Graphics, Inc. (415)335-1673 Protocol Engines, Inc. 2011 N.
