A few years ago a fellow worker and I started to work on an education platform for students to familiarize themselves with embedded \/low resource systems.<\/p>\n

We decided to take a DIMM-PC\u00ae\/520-IE with AMD\u00ae Elan\u2122 SC520 (133MHz) CPU from Kontron<\/a>.<\/p>\n

\"\"<\/a>The Core used for the AMD Elan is a 5×86 processor. This processor is an x86-compatible CPU which was introduced in 1995 by AMD for use in 486-class computer systems.<\/p>\n

Due to the internally-set multiplier of 4, the core runs at 133 MHz. The combination of the relatively large 16 KB\u00a0 write-back L1 cache and 133 MHz clock speed allows the 5×86 to perform >= an Intel Pentium 75 MHz processor in integer arithmetic performance.<\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

The Elan <\/a>CPU comes with following architecture.<\/p>\n

Our aim was to build an education system to show our students how PC systems are working and how easy it is to build a Linux OS from scratch for this kind of architecture. Secondly we want also to have a small development platform for third party projects.<\/p>\n

With 32MB of DRAM and up to 32MB of IDE compatible hard drive and full featured I\/O interfaces like serial port, LPT, IDE interface, Watchdog Timer, I\u00b2C Interface, General Purpose Chip Select and last but not least a beautiful Ethernet Interface suit all our needs for an easy to handle development platform.<\/p>\n","protected":false},"excerpt":{"rendered":"
