They aren’t called transputers, of course, but are called the XMOS xCORE devices.

Occam has been reincarnated as xC.

The xCORE+xC ecosystem has one currently unique advantage: the IDE tells you how long a piece of code will take to execute. That enables the 4000MIPS 32 core processors to do things that otherwise require an FPGA.

Unsurprisingly one of the INMOS architects, Prof David May, is a key player in XMOS.

Its peripherals are so full of options you can often configure them just right for more exotic uses. Like i needed something to decode a 16-bit address buss from a 6502 and do stuff. Turns out that with a tweak to the portmux settings it was possible to get 16 pins of a port exposed on a t4.1 and that i could hook the entire port to a single interrupt vector.

Only had to get used to the different clock between processor and peripheral. Easy to end up with the processor waiting for the peripherals. Stuff like reading/writing a port in one single go has a big impact.
