\section{Embodiments}

The following embodiments illustrate representative implementations of the
adaptive virtual machine architecture described herein. These embodiments
are provided for explanatory purposes only and should not be construed as
limiting the scope of the invention. Numerous variations, combinations,
and extensions will be apparent to those skilled in the art.

\subsection{Embodiment A: Adaptive Interpreter in a Stack-Based VM}

In one embodiment, the invention is integrated directly into a stack-based
virtual machine that executes threaded code. The runtime maintains the state
vector, updates execution heat on each word invocation, and applies temporal
decay and entropy filtering in background cycles.

The Jacquard Mode Selector evaluates metrics such as entropy slope, pipeline
pressure, and variance to switch between baseline, temporal, inference-driven,
and fully adaptive modes. Each mode configures the feedback loops (L1–L7)
differently, allowing the interpreter to maintain stable and optimized
execution across a wide variety of program structures, including tight loops,
branch-heavy logic, and deeply nested control flows.

\subsection{Embodiment B: Embedded Runtime for Constrained Systems}

In another embodiment, the invention is deployed as a compact runtime for
resource-limited devices such as microcontrollers, industrial controllers,
or safety-critical embedded modules. The feedback-loop architecture is
implemented using lightweight integer arithmetic, and the state vector is
compressed to a minimal subset (e.g., heat, entropy window, stability score).

The adaptive mode system allows the device to respond intelligently to
fluctuating sensor inputs, sporadic interrupts, and mixed real-time workloads
without requiring complex heuristics or manual tuning. Bounded adaptation
ensures deterministic timing when required.

\subsection{Embodiment C: Multi-Threaded Execution Engine}

In an alternative embodiment, the invention is implemented within a
multi-threaded execution engine. Each thread maintains its own state vector,
while a coordinating controller aggregates selected global metrics
(e.g., cross-thread stability, shared pipeline pressure) to inform mode
selection.

This embodiment is well-suited for high-performance computing contexts or
runtime environments that execute concurrent workloads exhibiting different
temporal or statistical characteristics.

\subsection{Embodiment D: Just-In-Time (JIT) Compilation Environment}

In some embodiments, the invention may be integrated with a JIT compiler.
The Jacquard Mode Selector influences JIT policies such as:

\begin{itemize}
	\item when to optimize hot paths,
	\item how aggressively to inline functions,
	\item whether to activate predictive prefetching,
	\item or when to adjust code generation strategies.
\end{itemize}

The feedback loops provide input signals derived from execution heat,
entropy stability, or workload phase changes. This integration enables the
compiler to target stable steady-state patterns while avoiding excessive
oscillation in code generation.

\subsection{Embodiment E: Adaptive Microkernel or Runtime Orchestrator}

In another embodiment, the invention is incorporated into a microkernel or
runtime orchestration layer responsible for managing low-level tasks,
scheduling, and resource allocation. The state vector may include
microkernel-specific signals such as:

\begin{itemize}
	\item task execution periodicity,
	\item inter-process message timing,
	\item or virtualization overhead.
\end{itemize}

The adaptive modes allow the kernel to adjust scheduling heuristics,
time-slicing strategies, and cache behavior based on observed workload
conditions, enabling improved determinism and reduced latency.

\subsection{Embodiment F: Statistical Inference-Driven Runtime}

In certain embodiments, the inference loop (L2) and inference-weighting loop
(L6) are given primary importance. The runtime employs statistical models—
potentially including Bayesian estimators, weighted moving averages, or
probabilistic classifiers—to predict upcoming workload shifts.

This embodiment is particularly effective in environments where workloads
exhibit repeated but non-uniform patterns, enabling the system to anticipate
transitions and adjust modes proactively.

\subsection{Embodiment G: Hybrid Adaptive System}

A further embodiment combines two or more of the previously described
approaches. For example, a stack-based interpreter may incorporate JIT-style
optimizations only when the inference system determines that the workload has
stabilized sufficiently. Alternatively, an embedded system may use a simplified
state vector but rely on a kernel-level orchestration layer for global mode
coordination.

\subsection{Embodiment H: Simulation and Analysis Environment}

In yet another embodiment, the invention is deployed as part of a simulation
or analysis environment used to evaluate program behavior, runtime stability,
or performance characteristics. The feedback loops and mode selector operate
normally, but no direct program is executed; instead, synthetic or replayed
workloads drive the system.

This embodiment enables developers to observe the adaptive behavior of the
system under controlled conditions, perform design space exploration, or
validate workload-specific behaviors.

\subsection{Embodiment I: Minimal-Loop Configuration}

Certain embodiments implement a reduced set of loops—for instance, using only
L1, L3, and L7—while still leveraging the Jacquard Mode Selector to control
adaptive behavior. This embodiment may be used in systems where power,
latency, or resource constraints preclude the use of more complex feedback
structures, while still providing workload-aware adaptation.

\subsection{Embodiment J: Distributed or Networked Runtime}

In some embodiments, the invention is implemented in a distributed execution
environment where multiple runtime nodes share or exchange selected metrics.
Each node maintains its own state vector, but a global or partially shared
controller may influence mode transitions to maintain stable behavior across
the distributed system.

This embodiment is suited for cloud, edge-compute, and multi-agent processing
environments.

\subsection{Summary of Embodiments}

The embodiments described above demonstrate that the invention is applicable
to a wide variety of execution environments, including interpreters, embedded
systems, microkernels, JIT-enabled runtimes, and distributed execution engines.
All such embodiments fall within the scope of the invention so long as they
maintain a state vector, coordinate internal feedback loops, characterize
workloads, and select or adjust execution modes in response to observed
runtime conditions.
