1-2
Overview
The UC-8410/8416/8418/8430 computer, which features a RISC CPU, RAM memory, serial ports for
connecting RS-232/422/485 devices, and 3 10/100 Mbps Ethernet ports, is designed for embedded
applications.
The UC-8410/8416/8418/8430 uses an Intel XScale IXP435 533 Mhz RISC CPU. Unlike the x86 CPU, which
uses a CISC design, the RISC architecture and modern semiconductor technology provide this computer with
a powerful computing engine and communication functions, but without generating a lot of heat. The built-in 16
MB NOR Flash ROM can be used to store the operating system, and 256 MB of SDRAM gives you enough
memory to run your application software directly on the UC-8410/8416/8418/8430. Moreover, the 32 MB
NAND Flash provides the capacity for data storage. In addition, the network capability provided by the 3 LAN
ports built into the RISC CPU combined with the ability to control connected serial devices makes the
UC-8410/8416/8418/8430/8430 an ideal communication platform for data acquisition and industrial control
applications.
The UC-8410/8416/8418/8430’s pre-installed open source Linux operating system can run software written for
desktop PCs, provided the software is ported to the computer with a GNU cross compiler. The process is easy,
straightforward, and your programmer will not need to modify the source code. The OS, device drivers (e.g.,
Ethernet, SRAM, watchdog, and Buzzer control) and your own applications, can all be stored in the NOR Flash
memory.
Software Architecture
The Linux operating system that comes pre-installed on the UC-8410/8416/8418/8430/8430 follows the
standard Linux architecture, making it easy to run programs that follow the POSIX standard. Program porting
is done with the GNU Tool Chain provided by Moxa. In addition to Standard POSIX APIs, device drivers for the
buzzer, SRAM and watchdog controls, and UART are also included in the Linux OS.
The UC-8410/8416/8418/8430’s built-in Flash ROM is divided into Boot Loader, Linux Kernel, Root File
System, and User Root File System partitions.
In order to prevent user applications from crashing the Root File System, the UC-8410/8416/8418/8430/8430
uses a specially designed Root File System with Protected Configuration for emergency use. This Root
File System comes with serial and Ethernet communication capability for users to load the Factory Default
Image file. The user directory saves the users settings and application.
To improve system reliability, the UC-8410/8416/8418/8430/8430 has a built-in mechanism that prevents the
system from crashing. When the Linux kernel boots up, the kernel will mount the root file system for read only,
