Title: Hierarchical data transmission system
Inventor: FUJIMOTO NAONOBU
IPC: H04L7/04
Filed: 1987-01-06
Granted: 1991-01-02
Abstract: ABSTRACT           A hierarchical data transmission system outputs a high speed second data train by step-by-step multiplexing first data trains.  A first signal processing part operates at a processing speed corresponding to the first data train.  A second signal pro-cessing part operates at a processing speed corresponding to the intermediate speed of the first data train and second data train.          A third signal processing part operates at the processing speed cor-responding to the second data train.  A first clock signal having a speed corresponding to the processing speed of the third signal pro-cessing part is generated.  A second clock signal having a speed corresponding to the processing speed of the second signal proces-sing part is generated by dividing the first clock signal.  A third clock signal having a speed corresponding to the processing speed of the third signal processing part, when the first signal proces-sing part operates in association with the third signal processing part, is generated by dividing the second clock signal after phase adjustment with reference to the phase information of the first clock signal.  The problem of accumulated delay times preventing the normal multiplexing process from being used, which is present in prior devices, is absent in the present invention.

It uses only visual graphical representations.  The methods are language free except for labels and comments.  In addition to eliminating language, the workstation completely eliminates separate compilers, linkers, and debuggers.  Computer programs are illustrated as visual road maps of the intended sequence of actions.  Each operational entity in a program graph on the screen is represented as an elemental "atomic" unit, called a "Softron".  The Softron is a multidimensional, graphical "atom" of programming information which has four modes of operation, termed "layers".  The four layers are Normal, where the basic functionality of the application resides; Initialization/Reset, responsible both for the startup values of important variables and for their values at strategic checkpoints; Error, which handles conditions outside design limits; and Input/Output, which performs human input/output and other I/O tasks.  Softrons reside in very general form in the workstation's library, and are optimized by the process of specialization.  Softrons may be grouped to form new Softrons by a process called Logical Zoom (TM),  Logically Zoomed Softrons may combine with other Softrons to form a computer program of arbitrary complexity.
