According to the demands of miniaturization

integrated design and comprehensive information utilization for integrated electronic system in aviation and aerospace field

this paper presents the UM-BUS.It is a high-speed

dynamic reconfigurable serial bus with

N

(32) concurrent lanes of mutual redundant structure available

and the maximum communication rate of 6.4Gbps.UM-BUS is formed by general bus-topology structure where up to 30 nodes can be connected directly to provide the capability of remote memory accessing with maximum communication distance of up to 40m.UM-BUS uses command/response protocol to attain QoS and real-time guarantee.In the case of allowing 50% reduced performance

any fault in

N

/2 lanes can be tolerant by reconfiguring the mutual redundant concurrent lanes automatically.On the basis of UM-BUS

this paper put forward a new architecture of embedded systems.This access type architecture is geared to the needs of embedded system control and measurement applications.It does not change the logic architecture of embedded system

but this access architecture can break the structural constraints of embedded systems' chassis.It can accomplish a plug and play of the functional module by means of dispersing the logic functions to the interior of the control measurement object.By using this architecture

the integration designing of integrated electronic systems is possible to complete.
