Randomized instruction set emulation

Compiled Instruction Set Simulation

An efficient method for simulating instruction sets is described. The method allows for compiled instruction set simulation using the macro expansion capabilities found in many languages. Additionally, we show how the semantics of the C case statement allows instruction branching to be incorporated in an efficient manner. The method is compared with conventional interpreted techniques and is sh...

Instruction Set Architecture Abstraction

This technical report describes CHERI ISAv3, the third version of the This report describes the CHERI Instruction-Set Architecture (ISA) and design. The purpose of this tutorial was to introduce the computer architecture Pydgin is a framework for rapidly developing instruction-set simulators (ISSs) from a but is particularly well-suited for exploring the hardware/software abstraction. The Intel...

Instruction Set Commutivity

We present a state property called congruence and show how it can be used to demonstrate commutivity of instructions in a modern load{store architecture. Our analysis is particularly important in pipelined microprocessors where instructions are frequently reordered to avoid costly delays in execution caused by hazards. Our work has signiicant implications to safety and security critical applica...
