Re: MPC885
What Linux linux distribution ?
With the developer board the freescale use the ARABELLA Linux but this version don't have atm derivers.

MPC885
Hi
I want to build a systems with two hardware interfaces:
1. Fast Etherent
2. UTOPIA L2
The system recive data by UTOPIA, it's make some elaborations and transmit data by Etherent. For this reason I'm thinking to use a network processor by Freescale MPC885 with O.S. Linux.
Someone...
Re: PCI bus interfacing
The fast solution is use a PCI controller like PLX 9054. It support DMA transfer.
It's about 20 E/piece.
A good book from PCI is :"PCI system architecture" by Tom Shanley

A good solution for ATU-C (CO) applications is the OCTANE by Conexant
It support: ADSL, ADSL2 and SHDSL adn have 8 ADSL ports with utopia interface

Re: configuring AT89C5131??
the procedure is:
For first USB_int
1. Usb_enable() set USBCONF
2. wait 5ms
3. configure_usb_clock() 48MHz
4. usb_configure_endpoint(number,type)
5. Usb_reset_endpoint
6. Usb_var_init
now the sheduler work and you enter in the...
Re: configuring AT89C5131??
Ok
In the ATMEL site you can find the :Implementing the USB Enumeration Process on the AT8xC5131/32/22 and AT8xC51SND1.
In this archive you can find the source code for the USB enumeration process.
I use the uVision2 V2.40 for compile the source code and the FLIP...
Re: configuring AT89C5131??
I have used the boot loader at the ATMEL site for the process of enumeration
(hxxp://www.atmel.com/dyn/products/product_card.asp?part_id=3011)
and it work.
I have changed only the part of the /* ENDPOINT 1 DESCRIPTOR */ with the characteristic of my device and the...
Other big difference is that with ARM 5 and above, the instruction set include a number of extra instructions witch enhance the performance of an ARM processor on typical digital signal processing (DSP) algorithms.

I have developed a PCI card base on PLX processor.
The PCI9054 is a good solution, if you are interested in high performance.
If you don't have much time buy the developer kit PCI 9054RDK-LITE
It's about 500 E.

Recently I had the same problem.
I want to build a system that perform a data transfer between my ADSL chip set modem ATU-C; Utopia L2 and my PC. The first solution is to use one network processor like INTEL or motorola, for build a ethernet interface.
But it's possible to use a interface...
ADSL Central Office
Hello
I’m looking for a possibile schematic for a Central Office (CO) interface with ADSL and ADSL2 modem.
I have found some micro-DSLAM by ZyXEL and Charles but I am interested to build one with a Ethernet interfaces.
Pls give me some idea?
Thx

Re: Mp3 encoder
Thx
I have found two chip that they execute MP3 coding:
1. Melody mp3 by Analog Devices with 21xx DSP
2. Mas 3587f encoder/decoder (data shhet : hxx://www.micronas.com)
Anybody have use them in same application ?
