PCBs on order
just a matter of waiting now..
I was thinking that while the CPU could overclocked really high, is also the issue of thermal problems with this plastic package.. So it is possible it could work at 64 MHz, but then running to thermal problems.. What I can tell 50MHz is to be the average.. Not really sure why.. Could just be the top limit of the CPU or a thermal limit..
Hopefully once this test is done, it will basically mark the end of the booster research, finally!! As RAM is the main bottleneck, then the next course of action is to speed up ST-RAM to 200% like troed has been working on lately.. If this can be incorporated into future booster designs, coupled with a maxed out CPU, then this would be the fastest 68000 system possible. At least with the current MMU limitations.
Of course at some point I will add fast-ram, so this could be running at 50MHz along with the CPU for example coupled with 200% ST-RAM speeds
of course I need to max out and finish the CPU acceleration work first.. Then I can concentrate on the RAM speeds etc.
It is also possible a 030 CPU could be adapted without too much work as the SEC CPU wires up almost the same as a 030 would. Of course the 030 brings caches for more speed and also 32bit access.
Though this kind of mixes in with what TerribleFire is trying to do as well. I may see if I can obtain one of his 030 boards as it is already wired up use with the STFM.. Just he is unable to get it working currently.. Though I am trying to help him get that project off the ground as there is no use in myself designing a 030 based booster if someone else has already designed it. Basically if I can add my own code into that design, then it will save myself a whole epic load of work as the hardware will basically be "off the shelf".
Should have been 2.3MHz.
