20 Communication Architectures for SoC
cation. This allows simple control register interfaces, thereby reducing SoC
wiring congestion that facilitates implementation. The AXI4-Stream protocol
provides a streaming interface for non-address-based, point-to-point commu-
nication like video and audio data.
The AMBA-4 specification has been written with contributions from 35
companies that include Original Equipment Manufactures (OEMs) and semi-
conductor and Electronic Design Automation (EDA) vendors. Some of the
early adopters of these new specifications include Arteris, Cadence, Mentor,
Sonics, Synopsys, and Xilinx.
AMBA 4 Phase Two, the next version of the AMBA specification, has
already been announced, and will focus on simplifying Multicore SoC De-
sign. ...
