embedded electronic brain (E2Brain)
E2Brain (pronounced E-Square-Brain) is a standard for RISC-based computer modules developed by Kontron. The E2Brain standard is particularly suitable for embedded computer applications in RISC architecture, where proprietary solutions have prevailed to date. Further development of the specifications is expected to benefit from the release of the standard.
E2Brain, as an open computer platform, is not comparable to the dedicated architectures such as the personalcomputers or Windows architectures, but can work under all computer architectures: PowerPC, x86 or others. It defines up to four high-speed ports for synchronous and asynchronous transmission and time-division multiplexing, three LAN ports for 10 Mbit/s, 100 Mbit/s and 1 Gbit/s, furthermore various ports for access to optical networks, such as UTOPIA, and also two interfaces for the CAN bus.
The E2Brain modules can communicate with each other via additional peripheral controllers. In addition to the scalable PCI bus, which is scalable from 32 bits and 33 MHz to 64 bits and PCI-X, RapidIO can also be used.
E2Brain has four connectors for communication, two of which are mandatory. The other two connectors can optionally be used for extended system connections for video, PCI-X, PCI-Express, Rapid-IO or Infiniband. The interfaces for LANs and the CAN bus are located on one of the mandatory connectors.
