Abstract: An IBM eServer zSeries™ system uses various types of microcode (firmware) that implement functions such as the execution of complex instructions in the CPUs, I/O operations performed by the ...

MythSim is a visual microcode simulator. It can take microcode, along with program code and data stored in memory, and "run" the code, with the computed results being written to memory. The user can ...

"The simulator was correct. It was not right." Last year I was debugging my41cx — my HP-41 microcode emulator — when I reached for an HP-16C simulator on the side. It gave me the answer I needed.

Microcode is a low-level layer of instructions that controls the basic operations of a microprocessor, such as arithmetic, logic, and memory access. It is often written in assembly language or binary ...

On January 8th Intel released new Linux Processor microcode data files that can be used to mitigate the Spectre and and Meltdown vulnerabilities in Intel CPUs. Using microcode files, an operating ...

In this assignment we will be writing portions of a LC-3 ISA simulator in C. This assignment implements (most) of the 16-bit LC-3 architecture as C functions. These functions parallel what a typical ...
