Off-Topic: Set Own Number on BlackBerry

2010 December 29 12:00 / Leave a Comment / Jakob

Ever since I got my BlackBerry smartphone, I was annoyed that the display said “My Number: Unknown number” in a number of places. I assumed that this would be automatic, just like everything else information-related on this device. However, I finally worked out how to “fix” the problem by manually setting my phone number.

Modeling Endianness

2010 December 26 17:58 / Leave a Comment / Jakob

Endianness is a topic in computer architecture that can give anyone a headache trying to understand exactly what is happening and why. In the field of computer simulation, it is a pervasive problem that takes some thinking to solve in an efficient, composable, and portable way.

This blog post describes how I am used to working with endianness in virtual platforms, and why this approach makes sense to me. There are other ways of dealing with endianness, with different trade-offs and overriding goals.

Wind River Blog: Iterative Hardware-Software Interface Design

2010 December 22 21:00 / Leave a Comment / Jakob

There is a new post at my Wind River blog, about iterative hardware-software interface design. It is a discussion with some examples of why hardware designers would do well to use virtual platforms to include software designers in the loop when designing new devices and their programming interfaces.
