Hierarchical multiprocessor architecture design in VLSI for real-time robotic control applications
This dissertation presents a layered restructurable multiprocessor architecture based on state-of-the-art VLSI technology for the realtime control of robotic applications. This architecture uses two VLSI chips as building blocks - Robotic Scalar Processor (RSP) and Robotic Vector Processor (RVP). These two VLSI processors may be used repeatedly to construct various computing structures to satisfy the computation and communication requirements of various robotic control applications. VLSI design and layout of the RVP have been largely completed. Two test VLSI chips, a 32-bit floating point adder and multiplier, have been set out for fabrication at 3.0 ..mu..m CMOS technology. The floating point adder test chip ha been received and tested. Preliminary testing results have shown that the floating point adder functions properly at 80 ns cycle time. The proposed architecture has been used to implement the Inverse Plant Plus Jacobian Control Algorithm for the control of a six-link robot manipulator. Significant computational performance has been achieved. The resulting VLSI architecture is capable of handling robotic control in real-time environments.
