CPUteho

CPUteho is a fictional central processing unit architecture used in illustrative discussions of processor efficiency and performance trade-offs. Created as a reference model, it aims to demonstrate how modern CPUs balance instruction throughput, latency, power consumption, and thermal constraints in real-world workloads.

Key design goals include high instructions-per-cycle performance, energy efficiency through dynamic voltage and frequency scaling, support for heterogeneous cores, and a modular instruction set that can be extended for specialized tasks such as vector processing, cryptography, or AI inference. The architecture emphasizes low-power decode and branch prediction costs, coarse-grained power gating, and aggressive clock gating to reduce energy use during idle periods.

Typical CPUteho configurations feature a multi-core layout with a mix of performance-oriented and energy-efficient cores, a unified memory subsystem with coherent interconnect, and optional on-chip accelerators. The microarchitectural concept uses a speculative out-of-order pipeline, simple but effective instruction scheduling, and a scalable cache hierarchy with configurable L2/L3 caches and potential high-bandwidth memory support.

In scholarly writing and industry commentary, CPUteho is treated as a hypothetical benchmark rather than a deployed product. It provides a framework to compare architectural choices and to discuss how design decisions affect performance per watt across different workloads and use cases.

Variants named CPUteho-1, CPUteho-2, and so on are used to illustrate different power envelopes, core counts, and accelerator configurations, ranging from mobile-oriented designs to data-center-scale implementations.
