Traditional bus system architectures on the base of 8/16-bit micro-computer and register-oriented interfaces for data acquisition and control have been used since 70s. The modern bus and non-bus system and network interconnections are compared and analysed. The possible transition from traditional message-passing bus (weak interaction nodes) to unidirection point-to-point interconnections with direct access distributed memory (high interactions) nodes for data aquisition and control systems are discussed. The low interaction nodes on the base of message passing can be changed by more efficient high-interaction nodes in operation control networks with distributed control access to equipment on the base of shared distributed memory subsystems and modern microprocessors. The Advanced distributed memory Data Acquisition and Control systems on the base of a new generation 16/32-bit general-purpose microprocessors (MP) and Digital Signal Processors (DSP) with RAMLINK-type (SCI-like) distributed memory interconnection are proposed and discussed. The advanced distributed MP-systems are proposed and analyzed on the base of a new generation MP and distributed memory.
