Impulse Processing Core
System Module Overview
The major system modules of the Impulse
Core are as follows:
Control Processor Module
This carries the main host CPU, a
powerful Intel processor for coordinating
all of the functions of the Impulse system.
It provides all processing for the core
and console local and network control
systems as well as control of the DSP
and router modules in the core. The
control processor provides fast storage
and network interfaces for rapid state
changes and low latency control. The
control processor module also provides
the Impulse Core Sync Subsystem, which
uses a dedicated network interface
for PTP synchronisation (or BNCs for
legacy inputs) to generate a timebase
for synchronising audio transfer on the
backplane. The control processor module
contains 2 small fans:- one on the front
and one on the base. The PTP, legacy and
ethernet connections are all described in
the system interconnects section.
Above the PTP connections in the core
control processor module is a recessed
reset button on the front panel (see right),
which allows a two-level core system
reset. A short press and release of the
reset button using a pointed object such
as a paperclip will trigger the first level,
“Short” reset, this acts as a reset of the
control processor module only. If the
button is held in the depressed position
for at least 4 seconds, the second level,
“Long” reset is triggered, which provides
a system level reset signal is asserted
as well. This signal is routed to the
backplane connector striped across
the core backplane to provide a system
level reset. This signal generally resets
all Management Controllers and Power
Sequencers in the core, thus causing
a system-wide power re-sequence and
system reset and initialization.
FIG 2 - UN6426 IMPULSE CONTROL PROCESSOR MODULE - FRONT VIEW
The control processor module also
controls two fans, the first is mounted on
the front of the module and the other is
mounted in the base of the module. The
‘Fan’ LED shows the ‘Fan’ status, if the
Fan LED lights solid green this indicates
that the Fans are OK, but if it lights red
this indicates a Fan failure. This status
LED along with the other status LEDs
are shown in the image on the left. The
LED status function table on the next
page describes the usage and behaviour
of these LEDs. Note: this or any other
failure within the core is also reported in
the UI.
