This is the fifth installment of the 80386 series. The FPGA CPU is now far enough along to run real software, and this post is about how it works. z386 is a 386-class CPU built around the original Intel microcode, in the same spirit as z8086. The core is not an instruction-by-instruction emulator in RTL. The goal is to recreate enough of the original machine that the recovered 386 control ROM can…

Modern Large Language Models (LLMs) suffer from static computation depth, wheretrivial and highly complex prompts consume identical vertical computational resources(FLOPs). While Mixture-of-Experts (MoE) architectures provide horizontal sparsity, theyfail to address the layer-wise redundancy and GPU thread divergence caused by token-levelrouting. In this paper, we propose In-Depth-MoE, a novel ar…

This paper proposes a practical hybrid gaming-computing architecture named VES-HGN X1, or VES Hybrid Gaming Node X1. Unlike speculative future processors requiring new semiconductor fabrication, the proposed system is built entirely on existing chipsets and commercially available hardware platforms. Its core components include an AMD X870E motherboard platform, an AMD Ryzen 9 9950X3Dclass process…

Silicon-based CMOS scaling faces increasingly severe limits from heat density, inter-connect delay, and the memory wall. This paper proposes VHS-C (Volumetric High-SpeedComputing) as a research roadmap for a post-silicon, volumetric compute-memory ar-chitecture. The proposed direction combines logic-memory proximity, heterogeneoustwo-dimensional semiconductor logic candidates, graphene/carbon sup…

This document presents a Technical Blueprint for a compute-and-data trans-continuum infrastructure design and architecture optimised for cost, power efficiency, time to results, and science-driven capability.

This paper presents a paradigm-shifting data preservation framework that completely bypasses the von Neumann storage bottleneck and Shannon's information limits. By utilizing a deterministic Resonance Mapping algorithm, physical digital payloads are evaporated into 256-bit mathematical coordinate seeds, reducing physical storage requirements to absolute zero bytes. The protocol guarantees O(1) co…

We present LSH-Burn, a Rust-based implementation of the LSH-SFA (Spacetime Field Attention) architecture using the Burn deep learning framework. LSH-Burn provides 1+N pluggable backend support for CUDA, Vulkan, AMD ROCm, WGPU, and ndarray backends. Key components include WavePacketProjector for token-to-wave-packet conversion, FieldAttention with Gaussian similarity, ResonanceCoupling for frequen…

Developing high-security anticounterfeiting with reliable authentication remains a significant challenge in preventing information leakage and economic losses from counterfeiting. Here, we successfully reported physically uncopiable optical system based on piezochromic polymer hydrogels (PPH). Pressure treatment induces a clustering-triggered emission transition from red to blue, driven by suppre…

The development and manufacturing process for Integrated Circuits (ICs) has become complex and globally distributed. System integrators use a mix of custom made logic with third-party Intellectual Property (IP) blocks, untrusted software tools, and external actors for manufacturing, post-production test, and validation. The many untrusted actors involved throughout the IC’s lifetime become a secu…

External GPU (eGPU) + NVIDIA Drivers on Linux: Solving the Display Manager Initialization Problem TL;DR: If your NVIDIA eGPU works in recovery mode but gives a black screen on normal boot, you're missing one critical Xorg option: AllowExternalGpus . This guide shows how to fix it properly on any X11-based Linux distribution. Introduction Installing NVIDIA drivers on a Linux system with an externa…
