Reference
If the Preferences window Resource Monitor parameter is set to Detailed, this
section of the window will display the following meters for each DSP.
Processor. This shows the amount of cycles used on the DSP, and is the main
indication of the amount of DSP processing power being used.
Linear Memory. This shows the amount of external linear memory being used.
Linear memory is used for tables.
Circular Memory. This shows the amount of external circular memory being used.
This memory is used for effects, physical models, and so on.
Long Circ. Memory. This shows the amount of external long circular memory
being used. This memory is primarily used for delay-based effects, including short
delays, choruses, flangers, and so on.
DRAM Memory. This shows the amount of external DRAM memory being used.
Each chip has 6 megabytes of DRAM, used primarily for samples and long delays.
Busses. There are three rows of lights, with each row representing one of the three
internal bus types: Local, Left-Flowing, and Right-Flowing.
Local Busses, shown in the top row, are the number of busses used within the DSP.
These busses are separate from the inter-chip busses.
Left-Flowing Busses, shown in the middle row, are the inter-chip busses which flow
from the slave DSPs to the master DSP. The left-flowing busses carry mixer
channels and audio outputs.
Right-Flowing Busses, shown in the bottom row, are the inter-chip busses which
flow from the master DSP to the slave DSPs. The right-flowing busses carry any
audio or stream inputs.
