Flexible design of high-speed readout electronics for astronomical detectors

Hardware design based on 20 MHz transputers, 120 ns first-in, first-out (FIFO) memory, and a 20 MHz counter is discussed. The two transputers are used to generate the states and to write them into the FIFO memory. The data generated by the transputers is written in the FIFO memory in parallel. The system design is characterized by a minimal state of 100 ns, a resolution of 33.3 ns, and fast data rate generation.
