The simple multiprocessor communication system

A very simple multiprocessor communication protocol has been presented in this paper. This protocol links a large number of peripheral processors with the central processor. Peripheral processors asynchronously transmit data packages at slightly varied speeds. This is of a particular interest when peripherals are utterly simplified and have no quartz-stable clock. The central processor accepts the data by means of multiplexer. The proposed protocol accepts data of varied speeds with the minimum number of samples per bit. For an undistorted signal, the number of samples per bit is very close to the theoretical minimum.
