Based on the most prosperous System on Chip (SOC) in the field of microelectronics, the open and real-time robot controller was analyzed, the application and development platform was built. By means of representative evaluation index, cohesion and coupling, the modularized design and the open architecture of robot controller were implemented. It is proved that the average distance between the same modules is short, and therefore the system is better cohesive. And the average distance between different modules is long, and therefore less coupled. Consequently, the whole system is excellent in openness. At the same time, the real-time schedule of controller tasks is analyzed from theory and experiment. It is proved that the controller based on SOC is excellent in real-time performance. The experiment showed that SOC-based robot controller is highly modularized, the parameters is clear, the architecture is easily implemented and revised, and therefore is adaptive to different controlling requirement and module building.

In this paper, the authors discuss a real-time on-chip communication service with a priority-based wormhole switching policy. The authors present a novel off-line schedulability analysis approach, worst case network latency analysis. By evaluating diverse inter-relationships and service attributes among the traffic flows, this approach can predict the packet network latency for all practical situations. The simulation results provide evidence that communication latency calculated using the real time analysis approach is safe, closely matching the figures obtained from simulation.

Computer programs are now available in various laboratories for the indexing and simulation of transmission electron diffraction patterns. Although these programs address themselves to the solution of various aspects of the indexing and simulation process, the ultimate goal is to perform real time diffraction pattern analysis directly off of the imaging screen of the transmission electron microscope. The program to be described in this paper represents one step prior to real time analysis. It involves the combination of two programs, described in an earlier paper(l), into a single program for use on an interactive basis with a minicomputer. In our case, the minicomputer is an INTERDATA 70 equipped with a Tektronix 4010-1 graphical display terminal and hard copy unit.A simplified flow diagram of the combined program, written in Fortran IV, is shown in Figure 1. It consists of two programs INDEX and TEDP which index and simulate electron diffraction patterns respectively. The user has the option of choosing either the indexing or simulating aspects of the combined program.
