标题:MEX 函数与 CL 函数:从积木范式到雕刻范式的生成元革命 —— 工业视角的重新审视 作者:刘文武 摘要: 现代计算机的本体是离散的——所有运算最终分解为整数和逻辑门,浮点数是后天发明的连续近似层。本文在 Odrzywołek(2026)开创的“生成元范式”(用单一函数递归嵌套替代多种异构运算)基础上,提出并系统对比了三个初等函数统一生成元: EML 函数(e^x - ln y):积木范式的起点,证明了单一生成元的可行性。 MEX 函数(x · e^y):积木范式的极致优化,仅用乘法和指数两个初等运算即实现完备性,硬件面积仅为 CORDIC 的 80%、EML 的 53%。 CL 函数(φ^x - φ^{-y},φ 为黄金比例):雕刻范式的开山之作,零外部常数自举,底数 φ 是离散差分算子的本征底数,是唯一能同时覆盖浮点 FPU 和整数 ALU 的统一生成元。 本文从工业硬件视角(面积、延迟、功耗、数值范围、离散域表现)进行系统对比,提出应用场景矩阵:MEX 是边缘 AI 推理芯片的面积最优解,CL 是密码学安全芯片、自主系统(航天/深空)和神经符号 AI 的终极候选基元。核心论点是:由于计算机的本体是离散的,而 φ 是离散差分算子的本征底数,CL 函数是当前唯一原生适配离散硬件的生成元——“通电即计算,拒绝查表,拒绝无用功”。 关键词:生成元,初等函数,NAND 门,黄金比例,计算机算术,AI 芯片,CORDIC,超越函数,离散微分,浮点-整数统一,MEX 函数,CL 函数,EML 函数,WWCL 元理论,雕刻范式,积木范式 优先权声明:MEX 函数(F(x,y) = x · e^y)作为初等函数统一生成元的定义、完备性证明和工业对比分析,于 2026 年 4 月首次公开记录于本预印本。CL 函数的优先权已由刘文武(2026,DOI: 10.5281/zenodo.19686211)确立。 Title: MEX and CL Functions: The Generator Revolution from Building-Block Paradigm to Sculpting Paradigm —— A Reassessment from the Industrial Perspective Author: Liu, Wenwu Abstract: The ontology of modern computers is discrete — all operations ultimately reduce to integers and logic gates, with floating-point numbers being an artificially invented continuous approximation layer. Building upon the "generator paradigm" pioneered by Odrzywołek (2026), which uses recursive nesting of a single function to replace heterogeneous operations, this paper proposes and systematically compares three unified generators of elementary functions: EML function (e^x − ln y): The starting point of the building-block paradigm, proving the feasibility of a single generator. MEX function (x · e^y): The ultimate optimization of the building-block paradigm, achieving completeness with only two elementary operations (multiplication and exponentiation). Its hardware area is only 80% of CORDIC and 53% of EML. CL function (φ^x − φ^{−y}, where φ is the golden ratio): The founding work of the sculpting paradigm, requiring zero external constants (the constant 1 self-emerges from CL(1,1)=1). Its base φ is the eigenbase of the discrete difference operator Δ, making CL the only generator natively aligned with discrete hardware and the only one capable of unifying floating-point FPU and integer ALU in a single unit. We conduct a systematic industrial comparison across hardware area, delay, power consumption, numerical range, and discrete-domain performance. An application scenario matrix is proposed: MEX is the area-optimal solution for edge AI inference chips, while CL is the ultimate candidate primitive for cryptographic secure chips, autonomous systems (space/deep-space), and neuro-symbolic AI. The core argument is: because the ontology of computers is discrete, and φ is the eigenbase of the discrete difference operator, the CL function is currently the only generator natively adapted to discrete hardware — "power on and compute, no lookup tables, no wasted work." Keywords: generator, elementary function, NAND gate, golden ratio, computer arithmetic, AI chip, CORDIC, transcendental function, discrete calculus, floating-point/integer unification, MEX function, CL function, EML function, WWCL meta-theory, sculpting paradigm, building-block paradigm Priority Statement: The definition, completeness proof, and industrial comparative analysis of the MEX function (F(x,y) = x · e^y) as a unified generator of elementary functions are first publicly recorded in this preprint in April 2026. The priority of the CL function has been established by Liu (2026, DOI: 10.5281/zenodo.19686211).
