Undefined Abbreviation

Hi!

I am writing a piece for my blog. In a few i.MX Datasheets is a statement such as:

"All four MMC/SD/SDIO controller IPs are identical and are based on the uSDHC IP."

After an extensive search I've been unable to find a conclusive definition for IP. e.g.

Interface Protocol

Interface Port

Internet Protocol

Intellectual Property

And so it goes...

Can I get a definitive meaning for it?

Sadly, there are quite a few of these sorts of errors in these datasheets.

Many thanks

Rob Napier

Thank you for responding. Since I originally posted the question I was able to find this and some of the other terms I've been struggling with at www.techtarget.com:

IP core (intellectual property core)

An IP (intellectual property) core is a block of logic or data that is used in making a field programmable gate array (FPGA) or application-specific integrated circuit (ASIC) for a product. As essential elements of design reuse , IP cores are part of the growing electronic design automation (EDA) industry trend towards repeated use of previously designed components. Ideally, an IP core should be entirely portable - that is, able to easily be inserted into any vendor technology or design methodology. Universal Asynchronous Receiver/Transmitter (UARTs), central processing units (CPUs), Ethernet controllers, and PCI interfaces are all examples of IP cores.

IP cores fall into one of three categories: hard cores, firm cores, or soft cores. Hard cores are physical manifestations of the IP design. These are best for plug-and-play applications, and are less portable and flexible than the other two types of cores. Like the hard cores, firm (sometimes called semi-hard) cores also carry placement data but are configurable to various applications. The most flexible of the three, soft cores exist either as a netlist (a list of the logic gate s and associated interconnections making up an integrated circuit or hardware description language (HDL) code.

A number of organizations, such as the Free IP Project and Open Cores, have formed to promote open sharing of IP cores.

I guess it serves a purpose but it's unfortunate that it needed yet another buzzword. As if the tech world is not already overflowing with buzzwords!

Thanks again for your help.

Great !
You found good explanation of the IP term.
