Re: F21d - Video, Mup21 instructions.

["Wayne Morellini" <waynemm@xxxxxxxxxxx>]

Dr Ting had a manual for Mup21 out, it might be on Jeffs shopping site:  
www.dnai.com/~jfox.

Jeff, good news, that 0.35 micron process (or 0.18 Micron process) might 
be good for a second edition of the chip.

More graphic colours and sound would be good (but this is I21 type 
matarial).  All we really need is preferably: video bus, memory bus, USB 
(or Firewire bus for I/O) buss, and legacy parallel/serial/Analoge and 
microwire (borad level electronics buss) ports.  Almost any thing could 
then be plugged in.

I think we however are getting beat on the memory side of things, a lot 
of memories are being designed for sequential access as backups to cache 
systems, solutions:

 small on chip cache
- A snow flakes chance in ..

 in package memory die
- A reduction in headache for Chuck designing memory modules and less 
charging time on the pads.

On chip memory (or should I say on memory F21)
-  I listed some alternatives of people with the facilities in last 
message.  Benifits, very tight interface to memory.

One of the things I forgot to put in the last message:

Optical Ram,  over 10 years ago Australian National Unitversity made a 
discovery that could increase the capacity of a CD by Several Million 
times.  Latter this croped up as the Blue disk (I think it might have 
been called rainbow disk).  Basicaly variouse rare earth materials could 
store millions of frequencies of light.  I believe that the disks 
exposed to light turned blue.  Recently the technology has cropped up 
again in the USA:

Optical Ram is a flat card working off of simular principle as above, 
using an ultrasonically guide laser it can read and write data at upto 
120Mb/s.  Realisticaly in the future (sciencefiction future) this could 
fit on the same chip.  I don't have the details but quick seek times are 
ussured.  Now realistically (non-sci-fi) this is a serial data stream, 
if random access is fast enough and multiple lasers could be 
synchronised together (say in parralel lines at 1 per bus bit) memory 
throughput could be vasely increased.  32*120MB/s (with I think at least 
30Gb per square centimeter), a lot of instructions.

Does anybody know of any fast semicoductor memories with fast random 
access though?  I suggested multibank ram before due to the fact that it 
yeilds a minium of 66 mhz (or was that 166Mhz) of random access in a 
worst case scenario (but now is old technology and is only used on some 
graphic cards).  What about sram, still used in low powered (f21 
equipement)?



Have fun, Wayne.
