Specifies the size of the DataIn queue in the DSP memory. The DataIn queue sends the data to the DSP.
DSP.C5x[x].DataInQSize = size
x = 0-(n-1) (A range of DSP cores where n equals the total number of DSP cores available.)
Read/Write
Integer
0x300
0x0000 – 0xFFFF
DSP.C5x[0].DataInQSize = 0x300
Changing the queue location or increasing the queue size can reduce the memory available to DSP functions. To change the DSP.C5x[x].DataInQSize settings, you must be familiar with the resource allocation in the CG board DSPs.
Caution: |
Due to a DSP architectural limitation, DSPs in a pair core must maintain the same HPI queue setting. Therefore, keep the settings for CmdQ, DataInQ, and DspOutQ the same in a pair core. For example: DSP.C5x[0..1].DataInQSize = 0x300 |
DSP.C5x[x].CmdQSize, DSP.C5x[x].CmdQStart, DSP.C5x[x].DataInQStart, DSP.C5x[x].DspOutQSize, DSP.C5x[x].DspOutQStart
