System 3 1-53
RZ5 BioAmp Processor
The zBus Interface The zBus Interface provides a connection to the PC. Data
and host PC control commands are transferred to and from
the DSP Block through the zBus Interface Bus, allowing for
large high-speed data reads and writes without interfering
with other system processing.
The I/O Interface Th
e I/O Interface serves as a connection to outside signal
sources or output devices. It is used to input data from the
preamplifier inputs and digital and analog channels. The I/O
Interface Bus provides a direct connection to each DSP.
DistributingDataAcrossDSPs
To reap the benefits of added power made possible by multi-DSP modules,
processing tasks must be efficiently distributed across the available DSPs. That
means transferring data across DSPs. The RZ5 architecture provides the zHop Bus
for this type of data handling.
ThezHopBus
The zHop Bus allows the transfer of single or multi-channel signals between each
DSP in the RZ5.
In RPvdsEx data is transferred across the zHop Bus using paired zHop Components,
including zHopIn, zHopOut, MCzHopIn, MCzHopOut, and MCzHopPick. Up to 126
pairs can be used in a single RPvdsEx circuit.
BusRelated 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.
RZ5Features
DSPStatusDisplays
The RZ5 include status lights and a VFD (Vacuum Fluorescent Display) screen to
report the status of the individual processors.
Status Lights
Two LEDs report the status of the multiprocessor's individual DSPs and will be lit
solid green when the corresponding DSP is installed and running. The corresponding
