Abstract

This invention relates to a method and apparatus for scattering r segments of a bit string obtained from one of m serial binary sources among r of n buffers and for gathering said r segments from said r buffers for recording in one of m sinks. The method steps include (1) parallel coupling r buffers to the source/ sink, (2) broadcast transmitting the bit string, and (3) electronically gating each of the r buffers on a byte count basis to secure transfer thereto of counterpart segments of the string. Apparatus for practicing the method includes a cross-point switch whose rows terminate source/sinks and whose columns terminate counterpart buffers. Multiple buffers can be lacked to a single row by centrally settable switches.
