This glossary describes some of the terms used in this manual. Where terms can have
several meanings, the meaning presented here is intended.
AMBA is the ARM open standard for multi-master on-chip buses, capable of running
with multiple masters and slaves. It is an on-chip bus specification that details a strategy
for the interconnection and management of functional blocks that make up a
System-on-Chip (SoC). It aids in the development of embedded processors with one or
more CPUs or signal processors and multiple peripherals. AMBA complements a
reusable design methodology by defining a common backbone for SoC modules. AHB
conforms to this standard.

See Advanced High-performance Bus.
AHB-Lite is a subset of the full AHB specification. It is intended for use in designs
where only a single AHB master is used. This can be a simple single AHB master
system or a multi-layer AHB system where there is only one AHB master on a layer.
