%X We have made an IP (Intellectual Property) core for the T425
   transputer. The same machine instructions as the transputer
   are executable in this IP core (we call it TPCORE). To
   create an IP code for the transputer has two aspects. On one
   hand, if we could succeed in building our own one and put it
   in an FPGA, we could apply it as a core processor in a
   distributed system. We also intend to put it in a VLSI chip.
   On the other hand, if we can extend our transputer
   development starting from a very conventional one to more
   sophisticated ones, as Inmos proceeded to the T9000, we will
   eventually find our technological breakthrough for the
   bottlenecks that the original transputer had, such as the
   restriction of the number of communication channels. It is
   important to have an IP core for the transputer. Although
   TPCORE uses the same register set with the same
   functionality as transputer and follows the same mechanisms
   for link communication between two processes and interrupt
   handling, the implementation must be very different from
   original transputer. We have extensively used the
   micro\-code ROM to describe any states that TPCORE must
   take. Using this micro code ROM for the state transition
   description, we could implement TPCORE economically on FPGA
   space and achieve efficient performance.
