I also visited the Oak Technology website (thanks, Calvin) at oaktech.com It looks to me like they and CRUS are very competitive on CD-ROM controllers, although I don't know enough about it to know who's ahead and also don't know who has more market share. You can look at CRUS offerings at cirrus.com if you want to compare for yourself. It looks to me like CRUS has the jump on Oak on DVD. Oak has a chip out also, but from the block diagram oaktech.com it appears that it requires a two-chip set with a DSP/servo chip in addition to the DVD controller. CRUS would seem to have a big advantage in that their chip cirrus.com is integrated into one. After looking at the "Product Bulletin" for the CR3700 and comparing to what Oak is offering with the OTI-9800, I think I understand better what CRUS means when they talk about their chip using PRML. CRUS has diverted from the architecture they and Oak used for CD-ROM, which used a DSP to process the analog signal from the media into a digital signal. Oak uses the same technology for DVD, which ends up making their solution use two chips. CRUS no longer uses a DSP per se but has instead adapted the signal processing scheme from their PRML read channel chips. This allows them to integrate everything onto one chip. It is not really PRML (if you read the product bulletin it becomes more clear they're not talking about PRML) but would seem to be a significant advantage nonetheless. I think they are calling it PRML because it uses a technique adapted from their disk drive chips which do use PRML. They wanted to call it out because it is a differentiating factor from the competition and they had to give it a name. G.P.
