A Comparative Architectural Analysis: Leading an Engineering Team to Deconstruct ISAs (ARM, x86-64, MIPS, RISC-V)

Research Overview: This research presents a strict engineering analysis and a cross-comparison of four major Instruction Set Architectures (ISAs). The paper goes beyond the independent academic description of each architecture. Instead, it provides a direct cross-analysis focusing on performance, code density, decoder complexity, and energy efficiency, strictly adhering to IEEE publication standards.

Leadership Methodology and Task Delegation: To complete this paper within the given time and structural constraints, I led a team of three additional engineers. The project was managed using a strategy based on task isolation, data quality control, and directing efforts toward precise final deliverables:

• Task Isolation: Team members were assigned specific research tasks. This included extracting raw architectural data for the target ISAs, analyzing addressing modes, and providing Assembly code examples for each architecture.

• Enforcing Cross-Comparison: To avoid the common mistake of listing each architecture’s features in isolation, I led an “analytical integration” process. The team was directed to cross-reference data so that the four ISAs are contrasted simultaneously under each engineering criterion (such as comparing pipeline complexity or memory models).

• Structural Control and Compliance: My leadership role focused on reviewing the outputs, filtering out redundant text, dynamically engineering the architectural tables to fit the two-column IEEE format, and ensuring that all conclusions were based strictly on hardware constraints rather than market popularity.

Final Outcome: A highly condensed and engineered research paper that identifies the fundamental differences and architectural decisions making each ISA the optimal choice in its respective application domain.
