From a news-item at VGR.com it appears that the current Articia-northbridges might still have DMA-related problems:
"Mr. S.W. who sends over screen shots of newer AmigaOne 800mhz G4 hardware, has sent over 2 screen shots of the new A1 with G4 running 'amigaone xe/g4 7451 800mhz, excalibur radeon 9000 pro 64mb ddr ram, valueram kvr133x72rc3/256 kingston'. He wants to know '.. if other aone users have that problem as well..', 'it never outputs the same checksum with dma enabled when testing an iso file which is larger than the swap space used'
You can see the Radeon 9000 Pro screen shots here: DMA On & DMA Off."

Articia: Still DMA-problems? : Comment 91 of 122 | ANN.lu |
Posted by Kjetil on 22-May-2003 05:38 GMT | In reply to Comment 71 (Anonymous): //TPC/IP will retransmit the packets until checksum is ok.
//There is no such thing as data corruption with TCP/IP.
So you think data is the same when the CRC is okey, have you ever used a modem?
Lots of HUBS to go to stress testing will have lots of CRC errors, if the CRC is the same that do not mean that the content is the same it only means algorithm making the CRC makes the same number out of different or the same data,
Example: 1+4 = 5, 2+3 = 5 |
