Performance real-time target machine - Mainboard & CPU

Inside, the Performance real-time target machine is equipped with a state-of-the-art industrial-grade mainboard in the ATX form factor. Speedgoat decided against the use of a passive or active bus backplane with a slot-CPU (PICMG SBC) because PCI bus signal integrity can't always be guaranteed by this setup (long bus signal lines). An ATX industrial mainboard doesn't show this potential problem because the PCI slots for the I/O modules are on-board and therefore closer to the chipset and their PCI bridges.

The standard CPU of the Performance real-time target machine is clocked at 2.13GHz and with its 4MB of 2nd level cache slightly outperforms the fastest Pentium-M (1.8GHz) we use in most of our other systems. Its huge cache can easily hold the xPC Target's kernel image and even large target applications (models) without the need to access the 'slower' RAM during real-time execution. The front side bus is nevertheless clocked at 1066MHz and the 2048MB RAM module at 800MHz. As an option RAM can be increased up to 4096MB.

Optionally the Performance real-time target machine is also available with higher clocked Intel Core 2 Duo CPUs running at 2.66GHz, 3.16GHz, or 3.33GHz. For the standard 2.13GHz and the optional 2.66GHz CPU we use the same type mainboard. For the optional 3.16GHz and 3.33GHz CPU we use a different type of mainboard with a newer chipset but less available PCI expansion slots for I/O modules (3 instead of 5). To nevertheless have enough expansion slots available Speedgoat offers several I/O expansion options for both mainboad types.
