TheETRAX CRIS is aRISCISA and series ofCPUs designed and manufactured byAxis Communications for use inembedded systems since 1993.[1] The name is anacronym of the chip's features:Ethernet, Token Ring, AXis - Code Reduced Instruction Set.Token Ring support has been taken out from the latest chips as it has become obsolete.
The CGA-1 (Coax Gate Array) was the first microprocessor developed by Axis Communications. It containsIBM 3270 (coax) andIBM 5250 (Twinax) communications. The chip has amicrocontroller and various I/O's such as serial and parallel. The CGA-1 chip was designed by Martin Gren and Staffan Göransson.[2]
AnElphel Reconfigurable Network Camera based on ETRAX FS CPU and Xilinx Spartan 3e FPGA.A FOX board LX 4+16 (4 MB flash and 16 MB SDRAM).
In 1993, Axis developed the ETRAX-1Ethernet Controller, which has 10 Mbit/s Ethernet and Token Ring controllers.
In 1995, Axis introduced the ETRAX-4SoC which contains a Ethernet Controller, CPU, Memory Interface,SCSI controller, and parallel and serial I/O.[3]
In 1997, Axis introduced the ETRAX 100 SoC which features a 10/100 Mbit/s Ethernet Controller,ATA controller, andWide SCSI controller. The chip introduced on-chip unified instruction and datacache along withdirect memory access.[4]
In 2000, Axis Introduced the ETRAX 100LX SoC which features aMMU,USB controller, andSDRAM interface. The CPU is capable of 100MIPS. The chip is able to run theLinux kernel without modifications except for low-level support.[5] The chip's maximumTDP is 0.35 Watts. As of Linux kernel 4.17, the architecture has been dropped due to being obsolete.[6]
The ETRAX 100LX MCM is based on the ETRAX 100 LX. The chip has internal flash memory, SDRAM, and an EthernetPHYceiver. The Chip can come with 2 MB flash and 8 MB SDRAM or 4 MB flash and 16 MB SDRAM.
The Axis Real-Time Picture Encoder Chip (ARTPEC) is a system on a chip (SoC) developed by Axis Communications.[7] There are currently nine generations of the chip, all of which run AXIS OS, a modified version ofLinux designed forembedded devices. Not all products developed by Axis Communications use its custom chip. The chip is typically found in high-performance devices such as higher-end cameras, while lower-cost devices use SoCs fromAmbarella.[8]
