ABSTRACT:
A Real-time Robotic Controller and Simulator (RRCS) with an MIMD-SIMD parallel architecture for interfacing with an external host computer provides a high degree of parallelism in computation for robotics control and simulation. A host processor receives instructions from, and transmits answers to, the external host computer. A plurality of SIMD microprocessors, each SIMD processor being an SIMD parallel processor, is capable of exploiting fine-grain parallelism and is able to operate asynchronously to form an MIMD architecture. Each SIMD processor comprises an SIMD architecture capable of performing two matrix-vector operations in parallel while fully exploiting parallelism in each operation. A system bus connects the host processor to the plurality of SIMD microprocessors and a common clock provides a continuous sequence of clock pulses. A ring structure interconnects the plurality of SIMD microprocessors and is connected to the clock for providing clock pulses to the SIMD microprocessors and provides a path for the flow of data and instructions between the SIMD microprocessors. The host processor includes logic for controlling the RRCS by interpreting instructions sent by the external host computer, decomposing the instructions into a series of computations to be performed by the SIMD microprocessors, using the system bus to distribute associated data among the SIMD microprocessors, and initiating activity of the SIMD microprocessors to perform the computations on the data by procedure call.
