Tf1260

[HardStep]

I got mine booting with ACA500+ and 2Mb chip ram. Showed all the TF1260 ram and sysinfo displayed 5Mhz. I have to deal with the Agnus socket connection and haven't had much time to play around lately. With original 512k OCS Agnus no boot.

Can an owner run bustest please?

cool please let us know how 060 specific demos run on it

what parameters are you interested in?


From readme on aminet:

How to use: bustest ADDR/K,SIZE/K,CHIP/S,FAST/S,ROM/S,MEGA/S ADDR/K hexadecimal start address of a memory region to test. This address can specify memory that does not appear in the system memory list (like a graphics frame buffer) or memory in the free list. bustest tries to check the address and will refuse to test it when it believes that the memory is used by anything else. BUT: it is possible to specify addresses that are not mapped to anything, resulting in thousands of bus errors. So be careful when using that option. SIZE/K size of the test region in bytes. You can use the suffix 'k' to specify units of 2^10 bytes and 'm' to specify units of 2^20 bytes. The size is rounded up to a multiple of 128 which is the granularity of the test loop. The default is 256 kilobytes. CHIP/S test an AllocMem'd region in chip memory. FAST/S test an AllocMem'd region in fast memory. ROM/S test the region starting at address $00F80000, i.e the kickstart ROM (or the RAM that is mapped there with the MMU if you use something like CPU FASTROM). MEGA/S show data rates in units of 2^20Byte/s instead of the normal 10^6Byte/s.

CHIP and FAST
Thank you in advance.

This is bustest fast at 80mhz

Later today after work I will post the result from the beta-firmware with burst on the memory.

[trixster]

Superb!

i was shocked by trixter's values.
i already thought the TF1260 is more a socket with RAM than a real turbocard.

Me too, tbh.

This is what my otherwise excellent A3660 manages on my A3000 (limited by the 030 bus emulation)

BusSpeedTest 0.19 (mlelstv) Buffer: 262144 Bytes, Alignment: 32768
========================================================================
memtype addr op cycle calib bandwidth
fast $07B40000 readw 152.4 ns normal 13.1 * 10^6 byte/s
fast $07B40000 readl 288.6 ns normal 13.9 * 10^6 byte/s
fast $07B40000 readm 290.1 ns normal 13.8 * 10^6 byte/s
fast $07B40000 writew 247.2 ns normal 8.1 * 10^6 byte/s
fast $07B40000 writel 495.1 ns normal 8.1 * 10^6 byte/s
fast $07B40000 writem 490.7 ns normal 8.2 * 10^6 byte/s

If you scale the values to 80MHz, the TF1260 seems to be about the same speed. Maybe the TF1260 is really designed like that (060 to 030 memory bus interface) so Stephen could reuse his 030 memory design.

[Chucky]

The reason is missing burst ram in the release firmware.. the beta have it. but it needs more testing (and other stuff)

[Chucky]

and btw. 3660 doesn't scale up.. it is kinda locked to the 25MHz 030 bus..

[Chucky]

meanwhile I found this picture. but sadly did not record what speed it is. I have a veague memory of at 50MHz as I am testing a LC and cpuspeed command by then required FPU will check later on real hw.

(this is my beta card. so 64MB of ram on that)

[trixster]

if that's 50mhz then that's faster ram access than the Warp1260

[Chucky]

I have tested gazillion different solutions..
this is the best I found. however this version of TF bugs out on my machine at 75..
so test at 62. as it IS beta

[trixster]

even better. that's competitive with the Warp1260 @ 80mhz

And faster than a Blizzard 1260 @ 80mhz by quite a margin for write long word :O

[Chucky]

and for fun new IDE speed using a very VERY crappy on-chip-DOM:

[trixster]

superb!

[wiz12]

Impressive, would that be around PIO3 speeds?

4,228,129 bytes/sec in beta...damn that's great!
