Building a computer is only the prologue. Once it works, the real systems puzzle begins: expose where time is lost, then reshape caches, access order, buffering, prefetching, and memory layout so the machine spends less time waiting.

Could you build this?
No This is an in-depth computer architecture and systems performance simulator focusing on hardware-level memory hierarchies and cache bottlenecks.
What it would actually take: Building this requires a cycle-accurate hardware simulator (similar to gem5 or custom microarchitecture emulation in C++/Rust) that models instruction pipelines, multi-level cache hierarchies (L1/L2/L3), memory bus bandwidth, DRAM timings, and TLB translations. Developing it demands specialized knowledge in computer architecture, CPU performance profiling, and systems hardware design that cannot be assembled by prompting an AI.
