Distributing Data Across DSPs
In RPvdsEx data can be transferred between each of the auxiliary DSPs as well as
the master DSP using zHop components.
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.
RX7 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).
