  abstract= "At the April 1998 WoTUG conference (WoTUG-21), it was
     reported that ST Microelectronics was ceasing production of
     most of the transputer family and its associated serial link
     components. The possibility of WoTUG members producing
     transputer-like devices to emulate many of the transputer\'s
     parallel processing and communication concepts was aired.
     The authors left this meeting with the challenge of
     designing and implementing their own transputer, preferably
     to be built in Field Programmable Gate Array (FPGA) devices
     rather than custom or semi-custom silicon, for ease of
     prototyping and for flexibility of modification and
     re-use.\</p\>\<p\> One year later, this paper
     outlines the progress that has been made. Rather than just
     producing processor logic using the standard logic design
     methods, the authors have written a compiler that translates
     occam into a number of output formats that can be fed to
     various logic implementation packages. Occam programs may,
     however, be joined to logic modules designed in a
     conventional fashion, using synchronised channels in the
     usual manner. In addition to the DS-Link interface that was
     announced by 4-Links at WoTUG-21, an OS-Link module has been
     designed by the authors, and both of these may provide
     external communication interfaces between occam-based
     hardware and the outside
     world.\</p\>\<p\> Although in their early
     stages, this paper illustrates several designs that show how
     occam may be used to specify small processors suitable for
     mapping onto FPGAs. It also shows how occam is an ideal fast
     prototyping mechanism for peripheral interfaces that connect
     to INMOS Links. "
