Network Lcd Terminal Hardware Implementation

As a kind of human-computer interface, display terminal is welcomed by vast unix's usres at the very beginning of its naissance. The users in the finance trade are attracted by its characteristics of low-cost, security and easy-operation,etc. This illustration introduces detailedly about one of GEIT's display terminals, about its designing ideas,theroies, plans, and final results.In hardware, this terminal adopts hyper-concentrated FPGA, which intergrates lots of functions into one chip, such as the logics between the display technology, network controlling technology, AT/XT interface keyboard, and the transition from CRT to LCD, and so on. And it has already achieved its low-cost, hyper-concentration and super-security.In software, with the small kernel and the super-stabilization, it introduces real time and multitasks operating system, standard TCP/IP protocol stack, combines most of the domestic terminal command, and can update the programs by serial interfaces and network.It adopts the fabric design which is according to somatology, and the friendly operating interface.It uses zero radial and lower radialized LCD as the display.And its MTBF achieves 20000 hours.
