- Sep 10, 2026 Issue Width and Its Diminishing Returns Why widening an out-of-order issue window costs area and energy faster than it buys performance, and where the wakeup, select, and bypass networks set the ceiling. computer architecture
- May 5, 2026 Register File Ports and Operand Delivery Why each extra read port on a register file costs area, latency, and energy, how banking and replication spread the cost, and what late operand collection buys a wide-issue machine. computer architecture
- Dec 24, 2024 Issue Width and the Structural Ceiling on Instructions per Cycle How a superscalar core decides how many instructions to start per cycle, which pipeline stage usually sets the limit, and why a four-wide machine rarely retires four instructions per cycle. computer architecture
- Jun 3, 2022 Why an In-Order Pipeline Stalls and What an Instruction Window Buys How dependencies, latency, and a fixed instruction supply bound an in-order pipeline, and why a sliding window of decoded instructions is the cheapest way out. computer architecture
