Difference between Motorola PowerQUICC and Motorola C-Port?

I am confused with Motorola.

Does the PowerQUICC compete with the C-Port chips or are they used for different applications?

Can anyone make sense of this?

The PowerQUICC 1 family is intended for SOHO and Frontier applications...IOW, things that are at the periphery of the network. C-Port and to some extent the PQ3 familys are intended for use indevices that are closer to the core of the network. These are devices like high bandwith optical routers, switches and whatnot. HTH!

To answer the original posters questions, it is rare that these would compete against each other in the marketplace.

The C-Port is a network processor - especially optimized for processing layer 2 through 7 while the PowerQuicc family has a general PowerPC processor at its core, plus some additional blocks surrounding it to aid in embedded system design.

Other than maybe memory controllers, I do not believe they share much in common. You can think of the PowerQuicc as an engineering toolbox

- they provide lots of tools to make it easy to do a wide varity of things. The C port is basicly at the other end of the spectrum: it's got a few focused applications that it is REALLY good at. If you aren't performing one of those applications, you probably don't want it (not to say you couldn't do it - just that it wouldn't be efficient).

Elroy is correct that you wouldn't find the C-Port sitting in a DSL modem under your desk at home - they are too specialized, too high power, and too costly. But other than that, you could find them both almost anywhere else in the network, as the need arises. You could easily find a SONET interface card in the core of the network with a little PQ1 on it talking across a backplane to a management card with a PQ3 on it.

Have fun,

Excellent point!

The price comparison gives an even better picture of where these guys would be used. The MPC855T runs about $23 depending on speed grade, and the MPC852T is about $9.50.

A PQ3 part is easily over $100. Definitely not good for the DSL router COGS or an interface card like Marc pointed out, but definitely good for a piece of $10k comm gear. =)
