DSP Requirements for TDM Plug-ins
The number of TDM plug-ins you can use at one
time depends on how much DSP power is avail-
able in your system. Since the TDM hardware on
Pro Tools cards provide dedicated DSP for plug-
ins, plug-in performance is not limited by CPU
processing power.
The DSP tables on the following pages show the
theoretical total number of instances of each Di-
giRack TDM plug-in that can be powered by a
single DSP chip on Pro Tools|HD-series cards.
DSP usage differs according to card type and
DSP chip availability.
DSP tables show the theoretical maximum
performance when no other plug-ins or sys-
tem tasks (such as I/O) are sharing avail-
able DSP resources. You will typically use
more than one type of plug-in simulta-
neously. The data in these tables are pro-
vided as guidelines to help you gauge the
relative efficiency of different plug-ins on
your system. They are not guaranteed per-
formance counts that you should expect to
see in typical real-world sessions and usage.
There are a total of nine DSP chips on a
Pro Tools|HD card (HD Core, HD Process, and
HD Accel). HD Core and HD Process cards pro-
vide identical chip sets. HD Accel cards provide
newer, more powerful DSP chips (making the
HD Accel card ideal for DSP-intensive plug-ins,
and for high sample rate sessions).
Not all plug-ins are supported on all types of
chips. The following tables indicate the number
of compatible chips per card.
