The SCore Live/Pro DSP card is used in the SCore Live for digital audio pro- The SCore Live/Pro DSP card is used in the SCore Live for digital audio pro-
cessing. The VDCA TDM bus interface allows the card to interchange audio
data, serial data, and program code with the bridge card and other DSP cards.
On the front panel, the card has two HD link ports consisting of 96 channels
of input and output each, resulting in 192 inputs and 192 outputs at sampling
frequencies of 48 kHz (for
of the two DSP clusters are depending on the configuration which is either
fixed or created with the configuration editor software and downloaded to
the card during runtime. A watchdog mechanism monitors the operation and
disconnects the card from the TDM bus in case of a failure. Furthermore, the
local voltages and temperatures are monitored and may be accessed by the
host application. The card can be hot-swapped.
