- Background Debug Mode
An on-chip debug interface supported by a special hardware port on
some processors. It allows to take full control over the CPU with
minimal external hardware, in many cases eliminationg the need for
expensive tools like In-Circuit-Emulators.
- Boot Protocol
A network protocol which can be used to inquire a server about
information for the intended system configuration (like IP address,
host name, netmask, name server, routing, name of a boot image,
address of NFS server, etc.
- Common Flash Interface
CFI is a standard for flash chips that allows to create device
independend drivers for such chips.
- Communications Processor Module
The magic communications co-processor in Motorola PowerQUICC? devices.
It contains SCCs and SMCs, and performs SDMA and IDMA.
- Compressed ROM File System
Cramfs is designed to be a simple, small, and compressed file
system for ROM based embedded systems. CramFs is read-only, limited
to 256MB file systems (with 16MB files), and doesn't support 16/32
bits uid/gid, hard links and timestamps.
- Concurrent Versions System
CVS is a version control system; it can be used to record the
history of files, so that it is for instance possible to retrieve
specific versions of a source tree.
- Dynamic Host Configuration Protocol
A network protocol which can be used to inquire a server about
information for the intended system configuration (like IP address,
host name, netmask, name server, routing, name of a boot image,
address of NFS server, etc.). Sucessor of BOOTP
- Direct Memory Access
A form a data transfer directly between memory and a peripheral or
between memory and memory, without normal program intervention.
- Embedded Linux Development Kit
A package which contains everything you need to get startet with an
Embedded Linux project on your hardware:
- cross development tools (like compiler, assembler,
linker etc.) that are running on a Host
system while generating code for a Target
system
- native tools and libraries that can be use to build a system
running on the target; they can also be exported on a NFS server
and used as root filesystem for the target
- source code and binary images for PPCBoot and Linux
- Our SELF package as example configuration for an embedded system.
- Fast Ethernet Controller
The 100 Mbps (100Base) Ethernet controller, present on 'T' devices
such as the 860T and 855T.
- File Transfer Protocol
A protocol that can be used to transfer files over a network.

The licenses under which the Linux kernel and much of the utility and
library code necessary to build a complete system may be copied, distributed
and modified. Each portion of the software is copyright by its respected copyright
holder, and you must comply with the terms of the license in order to legally copy
(and hence use) it. One significant requirement is that you freely redistribute
any modifications you make; if you can't cope with this, embedded Linux isn't for you.
The computer system which is used for software development. For
instance it is used to run the tools of the ELDK
to build software packages.
- Independent DMA
A general purpose DMA engine with relatively limited throughput
provided by the microcoded CPM, for use with external peripherals
or memory-to-memory transfers.
- Journalling Flash File System
JFFS (developed by Axis Communicartion AB, Sweden) is a log-based
filesystem on top of the MTD
layer; it promises to keep your filesystem and data in a consistent
state even in cases of sudden power-down or system crashes. That's
why it is especially useful for embedded devices where a regular
shutdown procedure cannot always be guaranteed.
- Second version of the Journalling Flash File System
Like JFFS this is a journalling flash filesystem that is based on the
MTD layer; it fixes some design problems of JFFS and adds transparent
compression.
- Joint Test Action Group
A standard (see "IEEE Standard 1149.1") that defines how to control the
pins of JTAG compliant devices.
Here:
An on-chip debug interface supported by a special hardware port on
some processors. It allows to take full control over the CPU with
minimal external hardware, in many cases eliminationg the need for
expensive tools like In-Circuit-Emulators.
- Memory Management Unit
CPU component which maps kernel- and user-space virtual addresses to
physical addresses, and is an integral part of Linux kernel operation.
- Memory Technology Devices
The MTD functions in Linux support memory devices like flash or
Disk-On-Chip in a device-independend way so that the higher
software layers (like filesystem code) need no knowledge about the
actual hardware properties.
PC
Card?
PC Cards are self-contained extension cards especially for laptops
and other types of portable computers. In just about the size of a
credit card they provide functions like LAN cards (including
wireless LAN), modems, ISDN cards, or hard disk drives - often
"solid-state" disks based on flash chips.
The PC Card technology has been has been developed and standardized by the
Personal Computer Memory Card International Association (PCMCIA),
see http://www.pcmcia.org/pccard.htm .
- Personal Computer Memory Card International Association
PCMCIA is an abbreviation that can stand for several things: the
association which defines the standard, the specification itself,
or the devices. The official term for the devices is
PC-Card.
- Real-Time Operating System
- Serial Communications Controller
The high performance module(s) within the CPM which implement the lowest
layer of various serial protocols, such as Asynchronous serial (UART),
10 Mbps Ethernet, HDLC etc.
- Simple Embedded Linux Framework
A simple default configuration for Embedded Linux systems that is suitable
as starting point for building your own systems. It is based on
BusyBox
to provide an init process, shell, and many
common tools (from cat and ls
to vi), plus some other tools to provide network
connectivity, allowing to access the system over the internet using
telnet and FTP services.
- Serial Management Controller
A lower performance version of the SCCs with more limited functionality,
particularly useful for serial debug ports and low throughput serial protocols.
- Serial Peripheral Interface
A relatively simple synchronous serial interface for connecting low speed
external devices using minimal wires.
- Motorola S-Record Format
Motorola S-records are an industry-standard format for transmitting binary files to target systems and PROM programmers.

The computer system which will be used later in you application
environment, for instance an Embedded System. In many cases it has
a different architecture and much more limited resoucres than a
typical Host system, so it is often not possible to develop the software
directly (native) on this system.
- Trivial File Transfer Protocol
A simple network protocol for file transfer; used in combination
with BOOTP or DHCP to load boot images etc. over the network.
