A Closer Look at Software Development for ARM’s big.LITTLE Processing – Part I

In the last month, I had the opportunity to get some hands-on experience with hardware virtualization and hypervisors. My knowledge so far on this has been mainly limited to what I could read about it and what other people are saying about it. However, the PowerPoint slides I’ve seen leave a lot of white fog between the bullet items. This didn’t make me feel very comfortable talking about this topic myself; but, there was no escape. Hypervisors play an increasingly important role for system designers in context of supporting multiple guest operating systems on the same device, or taking advantage of ARM®’s new big.LITTLETM processing. The fog is not all gone, but let me provide you some insight on what I found out. As a disclaimer, I’m not going to (and I cannot) write an expert almanac about all the aspects of virtualization covering Xen, VMWare, etc. Instead, I’m going to focus on my personal experience that I believe will be relevant to you as well. This post is the starting point for a series on this topic in this blog.

What Have Models Got to Do with It? Pre-Silicon SoC Software Bring Up

Transaction-level models are the main building blocks of virtual prototypes, which are used for early software development. In my last blog post, I briefly introduced the different kinds of software tasks and the implications for models. Today, I want to talk about the modeling requirements for early SoC bring up. As I mentioned, understanding the software requirements correctly provides two clear benefits: 1) it makes modeling easier through a more focused application and 2) it increases the value for the software developer through more tailored modeling capabilities such as debug features.
