Re: TT and NemBench

every hardware designer will say that if computer hardware is well designed than writing is always faster than reading. actually, I have no idea why writing is faster I am not sure but read from DRAM is destructive operation: meaning that you need to read and then to write back content.

Re: Memory access time

Here to add, that in ST it is much simpler: CPU's best RAM access cycle is 500nS. in both machines - ST and TT, access to the ST ram works in exactly the same manner. One memory slot is equal 250ns and CPU gets even memory slots, Shifter odd. but how Atari TT have 4 times bigger resolutions if ST-r...

^ every hardware designer will say that if computer hardware is well designed than writing is always faster than reading. But I am talking about cache. Writing to TT-Ram is almost same as writing to cache: 32bit write (100% hit): 16.181 MByte/sec Linear 32bit write (FastRAM) 15.641 MByte/sec only fe...

interesting fact: on some TT writing 32bit long word to FastRAM is ALMOST faster than writing to cache! How this is possible?

Re: TT and NemBench

Just to be clear: In Nembench section: 16bit read (100% hit) -> 15.873 MByte/sec (~202%) 16bit write (100% hit) -> 6.443 MByte/sec (~107%) 32bit read (100% hit) -> 31.695 MByte/sec (~201%) 32bit write (100% hit) -> 12.886 MByte/sec (~193%) is speed of CPU cache, right?

Re: Memory access time

But there is one interesting feature - FUNNEL chip. I read somewhere (maybe in Profibuch) that in a specific situation it can works as a 64bit cache for read cycles. I just found this article: http://www.stcarchiv.de/stc1990/10_ataritt.php They claim that ST-RAM is ALWAYS read and write in 64bit so...

One "stupid" questio:
Do you use DD or HD disc?
If you use HD and want to format it as DD then you must close hole in top left corner!
