Embedded_Systems_Sobel_Filter__BlockDesign-SDK

Based on a SW version of a Sobel filter written in C, using the Vivado HLS (High Level Synthesis) tool a hardware accelerator is build reducing the function's execution time on an ARM processor to the minimum using various optimizations through code directives. The optimizations are tested individually for their additional performance gains. Software running on a processor, no matter how well optimized it is, is slower than a hardware accelerator implementing the same functionality. Translating the functionality of a computationally intensive function to a HW Description language using all the available advantages HW parallelism and flexibility has to offer can be a really time consuming and often repetitive feat.

IDE Fix Pack

. Collection of unofficial bug fixes and performance optimizations for the RAD Studio IDE, Win32/Win64 compiler and Win32 debugger. IDE Fix Pack is an IDE plugin for RAD Studio 2009-XE6 that fixes IDE bugs at runtime. All changes are done in memory. No files on disk are modified. None of your projects are modified or benefit from the IDE Fix Pack other than being compiled faster. Only the IDE gets the fixes and optimizations.

Burn To The Brim

**Burn To The Brim** is a highly efficient archiving utility designed to solve the classic subset-sum (bin packing) optimization challenge. It intelligently selects and groups files and directories (documents, high-fidelity media, or raw back-ups) to optimally fill recordable Blu-Rays, USB drives or custom-capacity storage drives. By recursively scanning your designated folders, BTTB matches item sizes to your media capacity, finding a near-perfect selection in milliseconds and an absolute perfect packing configuration in just a few seconds. Burn to the Brim 4.0.0 introduces state-of-the-art machine learning semantic coherence logic to BTTB's classical packing algorithms.

Conscious Artificial Intelligence

This project is a quest for conscious artificial intelligence. A number of prototypes will be developed as the project progresses. This project has 2 subprojects: Object Pascal based CAI NEURAL API - https://github.com/joaopauloschuler/neural-api Python based K-CAI NEURAL API - https://github.com/joaopauloschuler/k-neural-api A video from the first prototype has been made: http://www.youtube.com/watch?v=qH-IQgYy9zg Above video shows a popperian agent collecting mining ore from 3 mining sites and bringing to the base. At the time the agent is born, it doesn't know how to walk nor it knows that it feels pleasure by mining. He has tact only (blind agent). The video shows learning, planning, executing and plan optimization.
