Detailed Description

Module to simulated SSR data output from ISIS.

Author:

Ed Bacho -- ebacho@slac.stanford.edu

Basic algorithm:

To start: Pulls all buffs from Freelist (FPA), sends buff to fork task Forktask load up buffs with data and put in ReadyList QUE Enable timer, if < 1 KHz datarate timer determined by datarate, one event per dma if > 1 KHz datarate time is 1 mSec, each DMA has N events To Stop: Disable timer Pull all buffers from the ReadyList QUE and puts back in Freelist (FPA)

Normal Operation Timer - runs every N milliSec, pulls buff from ReadyList and sends to LCB LcbRstCallback - when LCB finishes, buffer is send to fork task ForkTask - fills buffer with new data and puts it in ReadyList

Function Documentation

SSRSIM_init (  xLCBx  lcb, int  sendTaskPri, int  latpAddr, int  proto )

init the SSR simulate module Parameters: lcb  LCB handle sendTaskPri  priority of task created to send data to LCB latpAddr  address of unit to send data to proto  protocol number for event fabric Returns: none

Here is the call graph for this function:

SSRSIM_release (   )

shutdown the SSR simulate module Returns: none

Here is the call graph for this function:

int SSRSIM_setParm (  TDATA_DTEST  dataType, int  dataParm, int  tDuration, int  reqPacketSize32, int  evtPeriod, int *  actualPacketSize32 )

Setup and start data simulated SSR data from ISIS. Parameters: dataType  data pattern to load into buffer dataParm  parameter associated with given dataType tDuration  time in secs to output data, -1=forever reqPacketSize32  desired packet size, 8 to 1020, 0=random size evtPeriod  time in microSec between events, 100 (10KHz) to 30000000 (1/30 Hz) actualPacketSize32  returned packet size adjusted down if needed to achieve given evtPeriod within LCB bandwidth constraints, average size is returned if reqPacketSIze=0 for random Returns: status 0=sucess

Here is the call graph for this function:

SSRSIM_stats (   )

print stats Returns: none

SSRSIM_statsReset (   )

reset stats for printing Returns: none

void SSRSIM_stop (   )

stop SSR simulate data output Returns: none
