Overview

This document specifies the reconfiguration of the DSP (Digital Signal Processing) concept from fixed-function hardware to morphic-scalar-controlled reconfigurable processing units. The network swarm was assigned to analyze the current DSP implementation and propose a morphic-scalar-based reconfiguration.

Current DSP Concept Analysis

Existing DSP Modules

1. DSPTranslation.lean

  • Purpose: DSP to neuromorphic formal bridge
  • Features:
    • Q16.16 fixed-point arithmetic
    • STDP learning update
    • Geodesic cost calculation
    • Translation matrix operations
  • Limitation: Fixed-function DSP operations, not reconfigurable

2. DspErasureCoding.lean

  • Purpose: DSP-aware 3-stream erasure coding
  • Features:
    • 3-stream redundancy scheme
    • Spectral analysis for erasure detection
    • FPGA DSP slice integration
    • Q16.16 fixed-point
  • Limitation: DSP slices used as fixed multipliers, not adaptive

Current DSP Concept

Traditional DSP:

  • Fixed-function hardware (multipliers, adders, MAC units)
  • Predefined operation modes
  • Static resource allocation
  • No adaptation to signal characteristics

FPGA DSP Slices:

  • 8 DSP slices on Lattice iCE40 HX8K
  • Used as fixed multipliers in current implementation
  • [BEAUTIFUL_PROVISIONAL - 62.5% utilization (5 slices) in optimized morphic scalar - requires synthesis verification evidence with corpus provenance]
  • No runtime reconfiguration

Proposed Morphic DSP Concept

Core Principle

DSP as Reconfigurable Processing Unit:

  • DSP slices are not fixed multipliers but reconfigurable processing units
  • Morphic scalar state machine controls DSP configuration
  • OEPI threshold determines DSP allocation priority
  • DSP modes adapt to signal characteristics via scalar collapse

Key Changes

  1. Reconfigurable DSP Modes

    • multiply: Standard multiplication
    • accumulate: Accumulation for dot products
    • convolution: Convolution kernel
    • fft: FFT butterfly operations
    • filter: Digital filtering
    • adaptive: Adaptive filtering (OEPI-controlled)
  2. State-to-Mode Mapping

    • Morphic scalar state determines DSP operation mode
    • 16 scalar states map to 6 DSP modes
    • Dynamic reconfiguration based on scalar collapse
  3. OEPI-Based Allocation

    • Critical OEPI (≥95): All 5 DSP slices
    • Medium OEPI (70-95): 3 DSP slices
    • Low OEPI (<70): 1 DSP slice
    • Adaptive resource allocation
  4. FPGA Integration

    • 5 DSP slices for morphic scalar (62.5% of 8 available)
    • Parallel OEPI calculation uses 5 DSP slices
    • Reconfigurable based on scalar state
    • Remaining 3 DSP slices for other functions

OEPI-Based Resource Allocation

Allocation Rules

Critical OEPI (≥95):

  • Allocation: 5 DSP slices (100% of morphic scalar bank)
  • Rationale: Maximum processing power for critical situations
  • Use Case: Operator alert, emergency response, safety-critical operations

Medium OEPI (70-95):

  • Allocation: 3 DSP slices (60% of morphic scalar bank)
  • Rationale: Balanced processing for moderate priority
  • Use Case: Normal operation, query processing, collective response

Low OEPI (<70):

  • Allocation: 1 DSP slice (20% of morphic scalar bank)
  • Rationale: Minimal processing for low-priority tasks
  • Use Case: Idle state, low power mode, background processing

Dynamic Reconfiguration

DSP slices are dynamically reconfigured based on:

  1. Morphic scalar state transitions
  2. OEPI threshold changes
  3. Signal characteristics (via scalar collapse)
  4. Operator availability (affects OEPI)

FPGA Integration

Target Hardware: Lattice iCE40 HX8K

DSP Slice Budget:

  • Total DSP slices: 8
  • Morphic scalar allocation: 5 (62.5%)
  • Remaining for other functions: 3 (37.5%)

Morphic Scalar DSP Usage:

  • OEPI calculation: 5 parallel multipliers (5 DSP slices)
  • State-dependent reconfiguration: Dynamic mode switching
  • Adaptive processing: OEPI-controlled operation selection

Performance Impact:

  • Without reconfiguration: Fixed 5 DSP slices for multiplication only
  • With reconfiguration: 5 DSP slices for 6 different modes
  • Flexibility gain: 6x operational flexibility
  • Resource efficiency: Same hardware, more capabilities

Integration with Optimized FPGA

The morphic DSP concept integrates with the optimized FPGA implementation:

  1. Parallel OEPI Calculation

    • Uses 5 DSP slices for parallel multiplication
    • Tree-structured addition for minimal latency
    • Reconfigurable based on scalar state
  2. State Machine Control

    • Scalar state machine controls DSP mode selection
    • Auto-transition to low power mode affects DSP allocation
    • Operator unavailable triggers adaptive DSP mode
  3. Adaptive Processing

    • OEPI threshold determines DSP slice allocation
    • Signal characteristics (via scalar collapse) affect DSP mode
    • Dynamic reconfiguration without hardware changes
