Thanks for reply the problem is that if I use Block Read interface I will not be able to track the seek position in the image thats why I read 3 bytes at a time I use
logread interface for the same. rupesh ________________________________ From: Michael Schippling <sc...@santafe.edu> To: rupesh vishwakarma <rupesh2...@yahoo.co.in>; Tinyos-Help <tinyos-help@Millennium.Berkeley.EDU> Sent: Mon, 5 September, 2011 10:44:52 PM Subject: Re: [Tinyos-help] Telosb image processing rupesh vishwakarma wrote: > > yes I am working in 16 MHZ what can i do to make it fast process > Well...The MSP chip doesn't have a Multiply instruction (I'm a little surprised because the ATMEGA does and I never bothered to look). But it does do 16 bit integer Add and Sub so that's something... Therefore you need to be very careful with your math, and possibly hand-asm-code the inner loops. Also access to the external EEPROM may be rather slow, you should look into comparing the speed with the internal Flash memory for your image storage. Probably transferring larger blocks of data from ROM to RAM will help a bit too. MS
