\section{Summary of the Invention}

The invention introduces an adaptive virtual machine architecture that
continuously modifies its internal execution behavior in response to real-time
workload characteristics. Unlike traditional systems that rely on fixed or
manually selected configuration parameters, the disclosed architecture employs
a coordinated network of feedback loops, statistical inference mechanisms,
and supervisory mode selection to achieve autonomous, stable, and optimized
execution across heterogeneous and time-varying workloads.
\par\medskip
The system maintains a multi-dimensional \textit{runtime state vector}
representing execution frequency counters (referred to as ``execution heat''
by analogy), workload variability metrics (statistical variance, referred to
as ``entropy'' by analogy to information theory), time-based decay parameters,
instruction queue depth, stability metrics, and short-term statistical summaries.
As the workload evolves, these quantitative measurements provide a description
of its current behavioral characteristics, enabling classification as stable,
temporal, volatile, transitional, or mixed.
\par\medskip
A plurality of feedback loops (L1–L7) operate concurrently to regulate
different aspects of execution, such as cache usage, dictionary lookup strategies,
time-based decay coefficients, pattern recognition confidence weighting, and
statistical observation window sizing. Each loop responds to changes in the
state vector, enabling the system to reduce execution variance and optimize
throughput without manual tuning.
\par\medskip
A supervisory controller (L8), referred to as the Mode Selector (the name
``Jacquard'' being used by historical analogy to automated pattern selection),
evaluates the state vector and selects among multiple internally validated
execution modes. Each mode corresponds to a specific configuration of the
feedback loops and represents a stable, high-performance operating point
identified through design space exploration and empirical validation.
Transitions between modes are governed by bounded, non-oscillatory mechanisms
such as hysteresis thresholds or confidence scoring to ensure predictable
behavior even under rapidly shifting workloads.
\par\medskip
Through this combination of state-vector analysis, feedback-loop coordination,
and supervisory mode selection, the invention achieves robust and
shape-invariant execution performance across diverse input waveforms,
including sinusoidal, triangular, square-wave, burst-like, random, and
mixed-pattern workloads. The system converges quickly to an appropriate
steady-state configuration and maintains low variance even when exposed to
non-stationary or highly dynamic execution patterns.
\par\medskip
The invention is applicable to a wide range of execution environments,
including interpreters, stack-based virtual machines, embedded runtimes,
just-in-time compilation systems, microkernel-based platforms, distributed
execution engines, and real-time or soft–real-time systems. By providing a
general-purpose, workload-aware, and self-optimizing architecture, the
invention overcomes long-standing limitations of static configuration
approaches and enables predictable, stable, and high-performance behavior
without manual tuning or workload-specific adjustment.
