Glossary

Scatter-loading Assigning the address and grouping of code and data sections individually rather than

using single large blocks.

Scope The accessibility of a function or variable at a particular point in the application code.

Symbols which have global scope are always accessible. Symbols with local or private

scope are only accessible to code in the same subroutine or object.

Semihosting A mechanism whereby the target communicates I/O requests made in the application

code to the host system, rather attempting to support the I/O itself.

Signal An indication of abnormal processor operation.

Stack The portion of memory that is used to record the return address of code that calls a

subroutine. The stack can also be used for parameters and temporary variables.

SWI Software Interrupt. An instruction that causes the processor to call a

programer-specified subroutine. Used by ARM to handle semihosting.

Target The actual target processor, (real or simulated), on which the target application is

running.

The fundamental object in any debugging session. The basis of the debugging system.

The environment in which the target software will run. It is essentially a collection of

real or simulated processors.

Veneer A small block of code used with subroutine calls when there is a requirement to change

processor state or branch to an address that cannot be reached in the current processor

state.

Volatile Memory addresses where the contents can change independently of the executing

application are described as volatile. These are typically memory-mapped peripherals.
