Network Working Group Z. Eli Internet-Draft Hope Project Intended status: Standards Track May 29, 2026 Expires: November 30, 2026 Multi-channel Pixel Diagonal Flow (MPDF) Protocol Specification draft-hope-mpdf-protocol-01 Abstract This document updates the Deterministic Spatial Restoration Protocol (DSRP) specification by defining the low-level silicon memory pointer trajectories required to execute 4-to-1 Macro-Pixel Fusion. To achieve zero-CPU, hardware-wire speed execution and eliminate pipeline memory stalls, DSRP rejects single-row or single-column iterative scanning. This specification mandates a Dual-Row Parallel Shunt (DRPS) mechanism, where the hardware memory controller treats the 2D canvas as interlocking row-pairs, scanning horizontally with a 2-bit sliding window to output the 2-bit Absolute Gate Numbers within a single clock cycle.

Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. 2. Core Architectural Constraints and Canvas Topology 2.1. The Dual-Row Parallel Shunt (DRPS) Memory Scanning Blueprint To fulfill the non-probabilistic, zero-CPU execution directive of the DSRP architecture, compliant silicon memory controllers (DMA, FPGA, or ASIC registers) MUST NOT deploy abstract single-row iterative loops (Row-by-Row) or vertical column jumps (Column-by-Column). Hardware implementations of the DSRP encoder MUST enforce a parallelized "Dual-Row Parallel Shunt" (DRPS) data fetching sweep across the active 1.46 KB canvas cache buffer. 2.1.1. The Horizontal Dual-Row Sliding Razor Mechanism The physical silicon pointer driver SHALL bind adjacent horizontal rows into locked row-pairs (comprising Row N and Row N+1). The hardware memory read-head MUST act as a parallel dual-row horizontal razor, advancing synchronously from left to right across the 1500 columns using the exact geometric layout illustrated below: Column Line: 0 1 2 3 Row N (Top): [ b1 ][ b3 ] [ b5 ][ b7 ] ... ---> Horizontal Sweep Row N+1 (Bot): [ b2 ][ b4 ] [ b6 ][ b8 ] ... ---> Horizontal Sweep |________| |________| Block A Block B 2.1.2. The Stride Offset Addressing Equations Let Addr_RowN represent the absolute physical starting bit-address of the active row-pair top line in memory. Let W represent the constant horizontal row width of exactly 1500 bits. For any given horizontal macro-pixel block index k running from left to right along the column space (where 0 <= k <= 749), the hardware bus controller SHALL fetch the quad-cell elements [b1, b2, b3, b4] simultaneously within exactly ONE memory clock cycle via the following parallelized Stride Offset addressing equations: o Address of Bit 1 (Top-Left quadrant): Addr(b1) = Addr_RowN + (k * 2) o Address of Bit 2 (Bottom-Left quadrant): Addr(b2) = Addr(b1) + W o Address of Bit 3 (Top-Right quadrant): Addr(b3) = Addr(b1) + 1 o Address of Bit 4 (Bottom-Right quadrant): Addr(b4) = Addr(b1) + W + 1 Upon parsing the absolute boundary limit of the 1500th horizontal column (k = 749), the physical pointer subsystem MUST execute an instantaneous vertical row-stride jump to advance the base register to the subsequent layer: Addr_RowN_New = Addr_RowN + (2 * W) The parallel sliding razor mechanism SHALL then re-initiate scanning from the 0th column of the newly targeted row-pair. 3. Receiver Operation and Protocol-Layer Re-inflation The DSRP receiver subsystem SHALL execute data restoration natively at either the hardwired silicon layer or the software protocol/driver layer (e.g., inside a virtual network interface card driver or user- space network stack). The decoding framework is structurally equation- free and independent of specific physical layer silicon constraints. 3.1. The Protocol-Layer Blind Binary Unpacking Mechanism Upon extracting the 750-byte encrypted payload (6000 bits of Absolute Gate Numbers) from the transport channel, a compliant protocol-layer decoder MUST execute direct linear memory deployment. The decoding application SHALL instantly initialize a 12,000-bit memory canvas aligned to the strict 1500-column by 8-row topological boundaries. The protocol layer MUST process the incoming 6000 bits sequentially, expanding each 2-bit gate number token directly back into its target 4-bit spatial destination quadrants via blind bitwise indexing: o When parsing Gate Number 10: The decoder SHALL blindly assign value 1 to the sequential 1st and 4th bit positions, and value 0 to the 2nd and 3rd bit positions within the memory canvas array. o When parsing Gate Number 01: The decoder SHALL blindly assign value 1 to the sequential 2nd and 3rd bit positions, and value 0 to the 1st and 4th bit positions within the memory canvas array. This software protocol-layer execution loop achieves bit-perfect, deterministic reconstruction driven entirely by sequential array filling, completely avoiding CPU-intensive logical searching or probabilistic decompression algorithms. 4.
