External Memory Interface Description

I added a page to cover the External Memory Interface [EMIF]. The Asynchronous External Memory Interface (EMIF) bus is used in DSP and Digital Media System-on-Chip (DMSoC) ICs produced by Texas Instruments (TI).

I also updated the Firewire bus page to indicate the speed improvement from the up-coming release of the newest version.

I also up-dated a number of pages yesterday, but nothing to write about.....
