Getting Started with RTEMS
Although the finished cross-compiler is fairly easy on resources, building it can take a significant amount of processing power and disk space. Luckily, desktop computers have progressed very far since this guide was originally written so it is unlikely you will have any problems. Just do not use an old cast-off machine with < 1 GB RAM and a 1 Ghz CPU. Unless, of course, you enjoy waiting for things to complete.
The more disk space, the better. You need more if you are building the GNU tools and the amount of disk space for binaries is obviously directly dependent upon the number of CPUs you have cross toolsets installed for. In addition to the disk space requirements documented earlier for tool building, you will also have to have enough space to install the Cygwin environment.
