The IBM PPC750GX/GL is a 32-bit implementation of the IBM PowerPC family of reduced instruction set computer (RISC) microprocessors. The PPC750GX/GL is targeted for high performance, low power systems that use a 60x bus. The existing hardware is codename ‘Hickory’ Evaluation Kit.
Software (provided by ACME)
•
Linux OS is bootable & running on 750GX-Tsi108 evaluation platform (Hickory). The Linux kernel version is 2.6.11.8.
•
The necessary system controllers such as memory, processor bus, PCI bus register, Host interface, Gigabit Ethernet, etc are bootable and enabled on the platform.
•
Necessary Linux device drivers & features for platform hardware can be additionally developed and maintained.
•
A preview kit which allows potential customers to preview their Linux software offering on our 750 GX/GL evaluation board is provided. This preview kit can also facilitate a customer demonstration and development of Linux running on the 750 GX/GL evaluation board.

The software stacks is as shown. The Linux kernel hides the hardware details and provides services to upper layer. Utilities including chipset and all the necessary device drivers are called “BSP”.
•
C library is necessary for almost all user space programs. Busybox is the basic utility which is commonly used in the embedded environment. Busybox provides basic Unix commands to the users
