I also suggest you take a look at the "Transputer Assembly Language" book as it also has a lot of info on transputers. Here are the URLs: The Transputer HomePage - http://www.geocities.com/SiliconValley/Heights/1190 Transputer Assembly Language Programming - http://www.teleport.com/~johnro/transputer/transputer.htm C Programming on the Transputer - http://cs.smith.edu/~thiebaut/transputer/descript.html The transputer architecture - http://www.ludd.luth.se/~warg/projects/transputer.html Here is Sundance's description: The transputer is a high-performance RISC processor with its own internal and external memory. In addition, each unit has 4 communication links designed for high speed communication with other transputers. The communication links allow organizing the transputers into a linear array, ring, mesh or a custom configuration. The link configuration is specified by a network information file at program load time. Although logically they can be connected in many different ways, there must always be a link provided for the boot channel. The boot channel provides a reset and startup control for each transputer. Since only one boot channel output can be connected to one boot channel input, the practical effect is that for startup the channels are physically connected in a linear array. Note that since the boot channel can tie up two of the four channels, there are still two channels which are free for other connections. In addition, the boot channels can be used for regular communications after startup. Within this limitation other configurations can be achieved by using the non-boot channels.
