Renjith, Just wanted to know whether you have considered any other options.
What is your bandwidth requirement ? Is it say 1-20MB/s, >20MB/s Regards Swami PSP downloads at : http://software.ti.com/swcoe/intranet/reports/pds/PSP_releases.php Office : +91-80-25048629 ________________________________ From: renjith kumar [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 05, 2008 3:10 PM To: Subbrathnam, Swaminathan Cc: [email protected] Subject: Re: Davinci PCI module Is it some thing wrong in this ? Or any other suggestions ? I need more bandwidth, so thinking of using PCI. Does mvl-linux support driver for Host-davinci and target davinci. Any suggestion is appreciated ..

We are looking into, process 4 Video/Audio Channels (capture, encode, save,stream to Net, decode/display). So one Davinci may not be sufficient. So planning for 2 Davinci , whereas Slave (pci) Davinci chip will 1. Capture and encode 4 Videos (720x480) and 4 Audios, and encode to compression. 2. The Second (Host) Davinci will get it through PCI (as we thought as first plan) or Other Interface & 3 . The Host will save the streams, stream 4-AVs thru Network, Decode and Display 4-Ch at TV-Out with Quad mode. As we need more band width for the interface , initial thought was to use Davinci s PCI interface. have not think about USB yet. Which one does normally preferred. If it is PCI interconnection , does linux support both configuration for PCI at either side. ? If it is USB interface , does linux support this at either side ?

What are your needs w.r.t throughput, latency etc. in such a communication. Have you looked at using other means such as USB. swami ________________________________ From: davinci-linux-open-source-bounces+swami.iyer=ti.com<http://ti.com>@linux.davincidsp.com<http://linux.davincidsp.com> [davinci-linux-open-source-bounces+swami.iyer=ti.com<http://ti.com>@linux.davincidsp.com<http://linux.davincidsp.com>] On Behalf Of renjith kumar [EMAIL PROTECTED]<mailto:[EMAIL PROTECTED]>] Sent: Tuesday, August 05, 2008 6:19 AM To: [email protected]<mailto:[email protected]> Subject: Davinci PCI module Hi , I have a requirement on making 2 Davinci Chips (6467 x2), one for decoding purpose and the other for encoding multiple channels. Here out intension is to connect both the Chips with PCI interface , One as master and the other as slave. Have anybody done like this before ? What is the Driver configuration that we need to select in Linux ? Just selecting the Davinci PCI driver module for both device will do the needed. Or Is there special drivers we need to use for both separately ? Most of the Hardware Pins looks Bi-Directional, and is there any additional Glue Logic needs to be used for interconnecting the Slave and Master (Both in h/w and S/w) ? I am a newbie in this. ANY suggestions appreciated. -- Thanks'n Regards, Renjith. -- Thanks'n Regards, Renjith. -- Thanks'n Regards, Renjith.
