Igor, that is some food. [1] This is important for ADI clealry, as TI used to supply some or similar DSP chip for x2 modem. Remember reading that TI recently shipped 35th millionth chip for x2. [2] More importantly, AWRE is a xDSL partner of ADI. Since COMS has a large presenc in modm market, when they move to xDSL modem, ADI has a fair shot at COMS business. Which means AWRE will get the ride too. By the way, it explains why TI bought AMTX recently. satish kamat

Hi Igor, Seem to remember that you have a technical background... A couple of obscure technical memory related questions for you when you've got the time... from the article you posted: >>The 3Com design integrates a programmable DSP core, all requisite memory, and high-speed analog/mixed-signal circuits onto a single chip. The programmable DSP core provides a software upgradeable platform to support evolving communications industry standards while preserving hardware investments. Integrating all memory on-chip significantly reduces power consumption and board space. In addition to power and space savings, integrating analog/mixed-signal circuitry on-chip reduces eletromagnetic interference (EMI), making FCC compliance easier. << How is memory usually handled as a discrete component in current analog modems? How is memory integrated into a system on a chip as described in the article? Is this flash of some sort? About how much would be needed? and moving along to adsl... due to the complexity of adsl code, is significantly more memory needed? and will integrating memory into a system on a chip for adsl be a significant challenge? thanks in advance s

embedded memory ... Hi Igor, think I had the memory info all the time Trying to answer my own ?'s (post 2214): Looks like several processes out there... memory seems like it is DRAM... doesn't sound like it is/will be a huge issue for embedding into a chip for adsl... was asking the question(s) in the context of adsl modems and their components/count... have started gathering info on next generation chipsets... no one seems to be talking about embedded memory ... either it's already being done (by some) and not being mentioned or .... more likely something to look forward to in following generations.. am i on the right track?... good article from EE times 7/14/97 " Road to embedded DRAM divides --- Mitsubishi, Siemens race to next process..." ...In the 0.35-micron technology (Siemens), building blocks of 256 kbits of DRAM can be combined to form embedded DRAMs of up to 20 Mbits. Each block can be 8, 16, 32 or 64 bits wide, and blocks can be brought together to create an internal bus of up to 512 bits..." techweb.com Do you by any chance know about how much memory is needed for 56k and adsl?? any adsl specific info greatly appreciated... thanks s
