The INIC makes a MOST device accessible according to
the rules of the MOST Specification, even without an
application running on an EHC.
The OS81082 INIC provides a message-based interface
with the same physical interface and API as the
OS81050 INIC. It is encapsulated by a Function Block
(FBlock INIC). This allows the EHC to control the INIC
in the same way as other functions in the system.
Software
In the INIC’s architecture time-critical, resource-inten-
sive and fail-safe relevant parts of the network function-
ality are handled by the on-chip MOST NetServices.
This includes significant properties of the mandatory
Function Block (FBlock) NetBlock. A MOST device
based on INIC is able to answer requests to the
NetBlock, even if the application is not running or not
yet started on an EHC, thus providing maximum robust-
ness for the network client. The figure on the right shows
the software architecture for the INIC. It consists of an
on-chip stack and the MOST NetServices API V2 that
run on the EHC.
MOST NetServices API V2 Migration
The following software services are integrated on-chip as
parts of the MOST NetServices MiniKernel:
„ MOST Supervisor (MSV)
„ MOST Processor Control Service (MCS)
„ Socket Connection Manager (SCM)
„ Control Message Service (CMS)
„ Asynchronous Data Service (ADS)
„ Minimum NetBlock (NBMIN)
„ INIC Segmentation Service (ISS)
Wrapper modules within the MOST NetServices API V2
restore the Basic Layer (Layer I) of the former MOST
NetServices API V1 on the External Host Controller.
The INIC interfaces to external hardware using I²C and
PCM streaming ports. Additionally, it provides the inter-
face MediaLB. MediaLB supports high-speed communi-
cation for all MOST data types.
