back end

 

Functionality configured into a target server on the host determines how it will communicate with a particular target agent on the target.

For example, in VxWorks, you use a wdbrpc back end for Ethernet connections, wdbpipe for VxWorks simulators, wdbserial for serial connections, and wdbproxy for UDP, TCP, and TIPC connections. (The target server must be configured with a back end that matches the target agent interface with which VxWorks has been configured and built.)

backplane

 

A set of libraries that provide an interface between applications that access resources (consumers) and applications that contain resources (producers). Also referred to as Wind River management backplane, or WMB.

bandwidth

 

The bandwidth is the amount of data transmitted per unit of time, typically bits per second (b/s) or bytes per second (B/s)

BAR

 

Base address register.

bare metal application

BGP

 

Border Gateway Protocol

big endian

 

big endian is a method of storing data that places the most significant byte of multiple-byte values at a lower storage address. For example, a 16-bit integer stored in big endian format places the least significant byte at the higher address and the most significant byte at the lower address. See also little endian.

blocked state

 

If the underlying data link layer cannot accept any more packets or frames to send, the PPP stack enters a blocked state until this condition ends.

board support package (BSP)

 

Board Support Package (BSP) consists primarily of the hardware-specific code for a particular target board. A BSP includes facilities for hardware initialization, interrupt handling and generation, hardware clock and timer management, mapping of local and bus memory space, and so on.

BOOTP

 

Bootstrap Protocol
