New U-Boot boots ARM faster

September 30, 2010

5

A new version of U-Boot is out (here the announcement). U-Boot is a bootloader that aims to be flexible enough to be adapted to work on any architecture. This version (2010.09, that can be downloaded from their FTP server) adds Cache support to ARM architectures. The developers reported a couple of performance tests on a […]

New release of Icarus Verilog

September 28, 2010

Icarus Verilog is a compiler and simulator for one of the most used Hardware Description Language (Verilog of course). Today the developers released version 0.9.3; here is the announce on their SourceForge page. The Release Notes state that, other than bug fixes, the current implementation is becoming closer to the standard specifications. This new version […]

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 […]

ARM Cortex-M3 boards with STM32 chip

September 21, 2010

The ARM Cortex-M3 is the baseline of ARM 32-bits microcontrollers. Many products spawn from its design: the Cortex-M0 (a stripped-down version for small systems), the Cortex-M1 (specifically designed to be implemented in FPGA) and the Cortex-M4 (with Digital Signal Processing extensions). One chip family that contains the Cortex-M3 is the STM32. STMicroelectronics recently introduced the […]

Custom hardware modeling with QEMU (ELC 2010)

September 4, 2010

The videos of the presentations held at the Embedded Linux Conference 2010 have been recently made public on Free Electrons. I was particularly interested in one speech: Custom Hardware Modeling for FPGAs and Embedded Linux Platforms with QEMU (PDF slides and OGV video). John Williams (PetaLogix) illustrates the work they have been doing on reducing […]
