- I had to laugh at this. It clearly shows how stupid it is to put
- credence on (and before that, to circulate) unsubstantiated rumours.
- There really is nothing like having the truth to work with - if you
- haven't got the facts, don't try to invent them!
-
- What this rumour obviously derives from is an inaccurate description
- of the ARM250. This is the chip used in several of Acorn's recently
- launched products (A3010, A3020, A4000). It contains an ARM2aS cell
- (a slightly modified version of the ARM2 processor core, implemented
- in static logic so it can have its clock stopped without loss of
- data), an IOC cell, a VIDC1 cell and a MEMC1a cell. During
- development it was refered to internally as LUE, (pronounced "Louie")
- for reasons that I think I'd better leave to others to explain (if
- anyone around here dares ;-).
-
- The amusing part is how the spec for the chip has been blown up
- through the rumour mill, so that instead of VIDC1 it now seems to have
- VIDC20 as the video controller section, and instead of IOC there is
- something new (which I have never heard of) called IOC2. As Philip
- says, definitely one for the round file....
