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  appId )

init the SSR simulate module Parameters: lcb  LCB handle sendTaskPri  priority of task created to send data to LCB, 0=default of 60 latpAddr  address of unit to send data to appId  appId to be used within the CCSDS header 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, max 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

void SSRSIM_statsGetErrors (  int *  timerMiss, int *  dmaErrs, int *  itemErrs, int *  backPresErrs )

get error stats Parameters: timerMiss  if not NULL, return timer misses which indicates no buffer to send to LCB dmaErrs  if not NULL, return dma errs which indicate LCB did not process a list so list is probably incorrect or LCB problems itemErrs  if not NULL, return item error which are errors on one item in list, probably indicate cannot talk to destination of item backPresErrs  if not NULL, return backpressure errors which indicate timeout due to pause line from EBM being set Returns: none

SSRSIM_statsReset (   )

reset stats for printing Returns: none

void SSRSIM_stop (   )

stop SSR simulate data output Returns: none
