Glossary
This glossary describes some of the terms used in technical documents from ARM
Limited.
Advanced High-performance Bus (AHB)
A bus protocol with a fixed pipeline between address/control and data phases. It only
supports a subset of the functionality provided by the AMBA AXI protocol. The full
AMBA AHB protocol specification includes a number of features that are not
commonly required for master and slave IP developments and ARM Limited
recommends only a subset of the protocol is usually used. This subset is defined as the
AMBA AHB-Lite protocol.
See also Advanced Microcontroller Bus Architecture and AHB-Lite.
Advanced Microcontroller Bus Architecture (AMBA)
A family of protocol specifications that describe a strategy for the interconnect. AMBA
is the ARM open standard for on-chip buses. 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.
