System 3
Components such as MCzHopIn and MCzHopOut can be used for multi-channel
signals while components such as zHopIn, zHopOut, and MCzHopPick are used with
single-channel signals. Up to 126 pairs can be used in a single RPvdsEx circuit.
Bus Related Delays
The zHop Bus introduces a single sample delay. However, this delay is taken care
of for the user in OpenEx when Timing and Data Saving macros are used.
See "MultiProcessor Circuit Design" in the
multiprocessor circuit design techniques.
RX8 Features
DSP Status Displays
All high performance RX multiprocessors include status lights and a VFD (Vacuum
Fluorescent Display) screen to report the status of the individual processors.
Status Lights
Up to five LEDs report the status of the multiprocessor's individual DSPs. When the
device is turned on, they will glow steadily. If the demands on a DSP exceed 99%
of its capacity on any given cycle, the corresponding LED will flash very rapidly (~3
times per second).
Front Panel VFD Screen
The front panel VFD screen reports detailed information about the status of the
system. The display includes two lines. The top line reports the system mode, Run!
or Idle, and displays heading labels for the second line. The second line reports the
user's choice of status indicators for each DSP followed by an aggregate value.
The user can cycle through the various status indicators using the Mode button to
the left of the display. Push and release the button to change the display or push
and hold the button for one second then release to automatically cycle through each
of the display options. The VFD screen may also report system status such as
booting status (Booting DSP) or alert the user when the device's microcode needs
to be reprogrammed (Firmware Blank).
