It came to my attention today that there’s an alternative interpreter for the Python language which is faster and often viable: it’s called PyPy and uses Just-In-Time compilation to execute Python code. Just-In-Time compilation is a technique that is used successfully in many projects: the .NET Framework, Java, QEMU, … and it has also been […]

Simulating AT91 with Skyeye

September 27, 2010

Atmel AT91 is a series of common microcontrollers that contain ARM cores. The AT91SAM7 series in particular runs the ubiquitous ARM7TDMI. I found out that there is an open source program that emulates these microcontrollers (among many others): it is Skyeye. Skyeye is a project that emulates big and small microcontrollers, and for this reason […]
