A Multi-Core Architecture for In-Car Digital Entertainment
This paper presents a new multi-core architecture for in-car digital entertainment. Target functions vary
from terrestrial reception, digital reception, and compressed
audio, up to handsfree voice with acoustic echo cancellation
and USB media playback, possibly in different user modes
like single versus dual media sound. In the near future, new
functions like near field communication, wireless streaming,
storage, digital rights management, navigation and video become important. The main challenge is that the platform
must be open for future functions, which are unknown at
design time. Another challenge is to reduce the design effort
by maximizing reuse of hardware and software, especially
from related domains like Consumer Electronics (CE). This
paper describes an multi-core architecture using a network-on-chip, which provides the required flexibility and scalability. The area overhead, due to the network, is estimated to be
1.5% compared to the current architecture. Furthermore, it
is shown that the latency is comparable to the current architecture.
