Description
AHB 2.v6
AMBA AHB-lite version 2.0 with v6 extensions
AMBA AHB-Lite
Interface
A standard AHB-lite bus interface
AIPS
AHB 2.v6 to IPS interface unit
IPS
IP slave interface—A Freescale Intellectual Property Interface standard used for interfacing
to peripheral devices and control registers (slaves).
Pipeline
Act of initiating a bus cycle while another bus cycle is in progress. Thus, the bus can have
multiple bus cycles pending at one time.
Slave
A bus slave is a device that responds to a bus transaction, but never initiates a cycle on the
bus.
Transaction
A bus transaction consists of an address transfer (address phase) and one or more data
transfer(s) (data phase).
