    EdSim51

    EdSim51

    The 8051 Simulator for Students and Educators

    EdSim51, developed by James Rogers, is unlike an industry-standard simulator – this simulator has the student in mind. A virtual 8051 is interfaced with virtual peripherals such as a keypad, motor, display, UART, etc. The student can write 8051 assembly code, step through the code and observe the effects each line has on the internal memory and the external peripherals. Code written in C can also be imported into the simulator. Find out more, including the installation instructions and the user's guide at edsim51.com. You're obviously into technology. How about alien technology? ...

    Channel Code Copy of Compact Discs: This project has the goal to archive the complete content of CDs on the channel code layer. Here, the NRZI signal which stems from the laser-pickup of a CD player is recorded directly, providing sort of a pit-land photo of the CD. The resulting image file, in turn, is demodulated and decoded in software, i.e. within a virtual CD player.

    UniSIMD assembler is a high-level C/C++ macro assembler framework unified across ARM, MIPS, POWER and x86 architectures. It establishes a subset of both BASE and SIMD instruction sets with clearly defined common API, so that application logic can be written and maintained in one place without code replication. The assembler itself isn't a separate tool, but rather a collection of C/C++ header files, which applications need to include directly in order to use. ...
