I guess there are three: SIMD, MIMD & shared memory, MIMD distributed
memory. (UMA & NUMA)
No, transputers are certainly MIMD.
A transputer chip contains a complete CPU, possibly an FPU, a small
amount of RAM, and 4 high-speed serial links. You can actually ignore the
links if you want to, and use it as a simple CPU (I
can't think why you'd
_want_ to do this, but you can)
We did it for a laser printer. The transputer was doing the
emulations,BitBlt,graphics, had the "big" memory & output shift register.
Got the program downloaded from a NEC V25, which controlled the centronics
& V24. Was very easy to develope, because:
1.) the transputer supported DRAM directly
2.) debugging was easy, because you could download the programs via link
3.) pin compatible versions with/without FPU (FPU was used only for
postscript)
4.) Lots of application notes & support from INMOS at this time.
Just my .0002 cents
