Hybrid Stochastic-Deterministic
Video Processing Architecture

Revolutionary technology combining low-power approximate computing with precision GPU refinement for efficient, high-quality video processing in mobile, IoT, and consumer devices

SDPA = Stochastic-Deterministic Processing Architecture

The Challenge

Traditional video processing systems face critical inefficiencies in power consumption, precision allocation, and adaptability

Traditional Processing

  • High Energy Consumption: Deterministic arithmetic for every pixel
  • Over-Precision: Processing smooth regions with same precision as complex edges
  • Fixed Trade-offs: No runtime quality-performance adaptation
  • Bandwidth Inefficiency: No confidence metadata for selective refinement

Hybrid SDPA Solution

  • 60-70% Energy Savings: Stochastic Computing (SC) for smooth regions via SCA with thermal noise entropy sources
  • Smart Allocation: Precision processing via GRE only where needed (15% of pixels) based on confidence maps from SPB
  • Dynamic Adaptation: Real-time quality-performance optimization through feedback controller adjusting SCA/GRE balance
  • Confidence-Guided: Uncertainty metadata in PMF drives intelligent computational resource allocation decisions

The Innovation

ESSENCE OF THE INVENTION

Traditional video systems treat every pixel as equally certain and spend the same amount of compute everywhere. Our invention flips that model: the signal is encoded and processed as probability first, not as fixed numbers. A stochastic engine produces a fast, low-power approximation for the whole frame, while a deterministic engine is invoked only where the system is uncertain. Confidence (variance) travels with the data, so computation is allocated by need—edges, motion, text, and fine detail get more precision; stable regions do not.

  • Probabilistic Media Format (PMF): carries mean + variance (and correlation) so the decoder knows where certainty is high or low.
  • Two-path compute: a stochastic pass handles most of the image at very low power; a precision pass corrects only low-confidence regions.
  • Closed-loop control: live confidence maps drive selective refinement to hit target quality within power/latency budgets.
  • Progressive deployment: works in software today, accelerates on FPGA/DSP, and reaches maximum efficiency on dedicated SoCs.

The result is a quality–efficiency breakthrough: up to broadcast-grade visual quality with far fewer deterministic operations, enabling lower power, lower latency, and scalable performance from phones to automotive vision.

How It Works:

Traditional Processing: Every pixel processed with full deterministic precision, consuming maximum power and time.

SDPA Processing: Rapid stochastic computing (SC) processes most pixels at high speed with low power (green). The system then identifies uncertain regions (edges, textures - shown in yellow) and applies selective GPU refinement (bright green), achieving dramatic energy savings while maintaining quality.

System Architecture Flow

Real-time data flow from PMF encoder through transmission to hybrid SDPA decoder

PMF → SCA → SPB → GRE → Display Output

Data Flow: PMF demultiplexer parses incoming stream → SCA performs rapid stochastic reconstruction → SPB stores results with confidence metrics → GRE selectively refines high-uncertainty regions → Final composited output to display

Processing Pipeline

1

PMF Reception & Parsing

Receive frame block, parse header, demultiplex channels (mean, variance, correlation, correction)

2

Stochastic Bitstream Generation (SCA)

SCA loads mean values and configures entropy sources (thermal noise resistor or LFSR pseudo-random generator) with correlation parameters from PMF metadata

Analog Thermal Noise Source (Preferred Entropy Source for SCA)

The SCA uses physical entropy sources to generate random bitstreams for stochastic computing. The preferred implementation uses a 100 kΩ resistor whose Johnson-Nyquist thermal noise is amplified 500× and compared against mean pixel values to produce truly random bitstreams at 1-4 GHz with <100 µW power consumption per generator.

100 kΩ Resistor
Johnson-Nyquist Thermal Noise
Power: <100 µW

Noise Output Waveform

Random bitstream from thermal noise
Amplified 500× → Comparator → 1-4 GHz

3

Stochastic Computation

Arithmetic units perform video operations (color conversion, filtering) in stochastic domain - 64-256 pixels processed in parallel

4

Stochastic-to-Binary Conversion

Accumulators integrate bitstreams into binary values, compute confidence metrics, transfer to Shared Probabilistic Buffer

5

Confidence Map Synthesis

SPB combines SCA convergence metrics with PMF variance map: Confidence = w₁·(1-Var_PMF) + w₂·(1-Var_SC) + w₃·smoothness

6

Conditional GPU Dispatch

If high-uncertainty detected → GPU applies edge-aware filters and deterministic corrections to identified tiles

7

Output Composition

Blend SC approximate values with GPU corrections using confidence-weighted spatial blending with smooth transitions

8

Monitor quality metrics, power consumption, and latency → dynamically adjust parameters for subsequent frames

Complementary Research: Multiplexer as MAC Operator

Status: Complementary (Not Patented)

Publication: 2024-2025 (Academic Research)

Recent academic research demonstrates how multiplexers can function as scalable multiply-accumulate (MAC) operators in the stochastic computing domain. This technique is complementary to the SDPA architecture and could be integrated as an implementation detail within the Stochastic Compute Array (SCA) component.

Lee's Contribution

  • Focus: Hardware optimization for AI acceleration using stochastic computing
  • Innovation: Reimagines multiplexers as scalable MAC operators (MUX-8, MUX-16, MUX-32)
