\subsection{Detailed Description}
Module to simulated SSR data output from ISIS. 

\begin{Desc}
\item[Author:]Ed Bacho -- \href{mailto:ebacho@slac.stanford.edu}{\tt ebacho@slac.stanford.edu} \end{Desc}
Basic algorithm:

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

Normal Operation Timer - runs every N milli\-Sec, pulls buff from Ready\-List and sends to LCB Lcb\-Rst\-Callback - when LCB finishes, buffer is send to fork task Fork\-Task - fills buffer with new data and puts it in Ready\-List
