  Ptolemy 
  n  :  (2nd  century  AD)  proposed  a  geocentric  system  of  astronomy 
  that  was  undisputed  until  Copernicus  [syn:  {Ptolemy},  {Claudius 
  Ptolemaeus}] 
 
  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  Ptolemy 
 
  A  flexible  foundation  for  the  specification,  simulation,  and 
  rapid  prototyping  of  systems.  It  is  an  {object-oriented} 
  framework  within  which  diverse  models  of  computation  can 
  co-exist  and  interact.  For  example,  using  Ptolemy  a 
  {data-flow}  system  can  be  easily  connected  to  a  hardware 
  simulator  which  in  turn  may  be  connected  to  a  discrete-event 
  system.  Because  of  this  Ptolemy  can  be  used  to  model  entire 
  systems.  In  addition,  Ptolemy  now  has  code  generation 
  capabilities.  From  a  {flow  graph}  description,  Ptolemy  can 
  generate  both  {C}  code  and  {DSP}  {assembly  code}  for  rapid 
  prototyping.  Note  that  code  generation  is  not  yet  complete, 
  and  is  included  in  the  current  release  for  demonstration 
  purposes  only. 
 
  Version  0.4.1  includes  a  graphical  algorithm  layout,  code 
  generator  and  simulator.  It  requires  {C++},  {C}  and  has  been 
  ported  to  {Sun-4},  {MIPS}/{Ultrix};  {DSP56001},  {DSP96002}. 
  Ptolemy  is  an  active  research  project.
