- I asked questions similar to these a month or two ago, but nobody answered.
- Perhaps somebody knows the answers now.
-
- 1) What is the speed of the Falcon's memory (Somebody said it had 0 wait
- states which seems to imply 16MHz, but they may have been wrong)
- 2) How does the DSP access the main memory (Somebody said it is not connected
- to the data bus, in which case I suppose it must be some kind of serial link)
- 3) Does the TOS V4 use the DSP to speed up things (for that matter does it
- make intellegent use of the Blitter?)
- 4) Is the data bus between the memory and the 68030 16 or 32 bits wide (There
- seems to be an argument going on about this).
- 5) Why does the benchmarks that I have seen posted here only indicate an
- approx 3x speed increase and real-world tests (excluding any disk access)
- only twice as fast? If the data bus is twice as wide, the memory twice as
- fast, the processor at least twice as efficent and running at twice the clock
- speed it should be more like 10 times the speed.
