Hello Transputer fans! This is a site for the PC transputer emulator. What's happening... November 2011 - Release of the PC based T414 Transputer emulator (jserver version 5.1). Click on the What's happening tab for more details and history. Overview Welcome to the combined Inmos T414 Transputer and Iserver emulator for the IBM Personal Computer and IBM PC compatible, usually refered to simply as PC Transputer emulator. The diagram shows the functionality of the software. The emulator provides 4Mbytes of memory for the T414 transputer. It runs in a Windows Win32 command console (within XP, Vista and Windows 7). It emulates a 20MHz T414 Rev B transputer. The EMI emulates multiplexed DRAM with 3 processor cycle access (i.e. MemConfig wired to MemAD4). This PC transputer emulator program started out as a port of the original T414 transputer emulator (called jserver) written by Julian Highfield in the mid-late 90's (refer to http://spirit.lboro.ac.uk/emulator.html) for both the Macintosh computer and common unix variants. The jserver program available on this website is now fully debugged and works with both the Inmos Occam toolset D7205a and the Inmos ANSI C toolset D7214c. A considerable number of bugs have been sorted over the past five years with the original source code. The emulator behaviour now minic the actual Inmos T414 operation and cycle timing (as accurate as it can be done). The code has been modified to emulate a Inmos T425 transputer (by using the /SH 425 option). It was more recently modified to emulate a Inmos T400 (/SH 400 option) and the T800 transputer with it's integrated floating point unit (/SH 800 option). This T414 emulator allows Transputer executable file (normally refered to as bootables or .btl files) generated for a single transputer network connected to the Iserver via link 0 to be executed. For information, the Iserver is a host keyboard, screen and file handler. There are a number of example .btl files in the attachments (see Installation Instructions). In addition, you can develope Occam or C code for Transputers without any hardware (for non commercial use of course!). The only stipulation is that you have the Inmos toolset software. Ram Meenakshisundaram's Transputer website is a good source for (refer to http://www.classiccmp.org/transputer/software/languages/) the Occam D7205a and ANSI C D7214c software. There are also installation guides in the same directories. Of course, only code compiled for a single T414 (or TA), T425, T400 or T800 using link 0 can be run on this transputer emulator, BUT if you have access to real hardware then bootables (compiled by the emulator) can be run on multiple Transputer architectures. Enjoy. If you have any queries or feedback, concerning the T414 transputer emulator or webpage improvement suggestions, please let me know. I will be happy to help. For all other Transputer queries please use the usual bulletin board website (refer to Usenet group - comp.sys.transputer or more recent forum group - comp.sys.transputer). Gavin  |
