I am just finishing off reading the chapters of the Processor and System-on-Chip Simulation book (where I was part of contributing a chapter), and just read through the chapter about the Tensilica instruction-set simulator (ISS) solutions written by Grant Martin, Nenad Nedeljkovic and David Heine. They have a slightly different architecture from most other ISS … Continue reading “Interrupts and Temporal Decoupling”
I just read a quite interesting article by Christian Pinto et al, “GPGPU-Accelerated Parallel and Fast Simulation of Thousand-core Platforms“, published at the CCGRID 2011 conference. It discusses some work in using a GPGPU to run simulations of massively parallel computers, using the parallelism of the GPU to speed the simulation. Intriguing concept, but the … Continue reading “GPGPU for Instruction-Set Simulation – Maybe, Maybe not”
Since I have a certain interest in debugging, I was happy find the article “Guidelines for SystemC – Debugger Integration” at the usually interesting Design and Reuse website. However, I must say that it was pretty disappointing.
I just found a recent paper on the topic of parallel simulation of computer systems. Christopher Schumacher et al., published an articles at CODES+ISSS in October of 2010 talking about “parSC: Synchronous Parallel SystemC Simulation on Multicore Architectures“. Essentially, parallel SystemC.
Being a bit of a computer history buff, I am often struck by how most key concepts and ideas in computer science and computer architecture were all invented in some form or the other before 1970. And commonly by IBM. This goes for caches, virtual memory, pipelining, out-of-order execution, virtual machines, operating systems, multitasking, byte-code … Continue reading “The 1970 rule strikes again: Virtual Platform Principles in 1967”
It must have been Google Alerts that send me a link to the HOTOS 2007 (Hot Topics in Operating Systems) paper by Tal Garfinkel, Keith Adams, Andrew Warfield, and Jason Franklin called Compatibility is not Transparency: VMM Detection Myths and Realities. This paper is slightly less than a year old today, so it is old … Continue reading “VMM Detection Myths and Realities from a Simics and Embedded Perspective”
