    We developed a new algorithm for designing optimal cellular interconnects (OCI) to speed up processor communication in SIMD machines. This deterministic OCI design is the optimal topology for space-invariant patterns, minimizing clock cycles per data shift.

    Area of Science:

    • Computer Science
    • Electrical Engineering
    • Parallel Computing

    Background:

    • Single-instruction multiple-data (SIMD) machines rely on efficient inter-processor communication.
    • Optoelectronic interconnections offer high-speed communication potential.
    • Current methods for designing interconnects can be inefficient and rely on trial-and-error.

    Purpose of the Study:

    • To introduce a novel algorithm for designing optimal cellular interconnects (OCI).
    • To demonstrate the OCI architecture's optimality for space-invariant interconnect patterns in optoelectronic SIMD machines.
    • To provide a deterministic design method, replacing previous trial-and-error approaches.

    Main Methods:

    • Development of a novel deterministic algorithm for OCI design.

    • The new algorithm provides a deterministic and efficient design process.

    Conclusions:

    • The novel algorithm enables efficient design of optimal cellular interconnects for SIMD machines.
    • The OCI architecture significantly accelerates processor communication in optoelectronic systems.
    • This deterministic approach enhances the practicality and scalability of SIMD system design.
