Case Study RDC R8610 Information Board Controller with Web Interface
Information Board Controller
Completed project - November 2006
large and giant
The objective is to
platform for controlling high-
resolution electronic board which
is built from big quantity of
universal LED cells. It is necessary to
provide platform scalability by applying
Embedded Linux OS, while the device cost
must not exceed 60 USD when manufactured in a medium run.
As the basis for hardware platform we choose an inexpensive RDC R8610 processor
that has x86 core architecture, 32-bit RISC core and 133 MHz. This processor has a
big set of built-in periphery (PCI rev2.1, 2 x Ethernet MAC, USB 2.0 Host, LPC,
UARTs, GPIO, SDRAM-controller), and its performance allows executing processing
tasks and displaying various graphics onto information board. The selected
microprocessor does not require any cooling system.
ST FLASH M29DW128 (NOR organization type) stores bootstrap loader, operating
system, application software and controller's settings. Samsung FLASH K9F5608
(NAND organization type) stores commercials and other multimedia information
and has 1Gb memory. NAND Flash controller is realized on Altera CPLD MAX2
EPM270, and also a specialized interface is implemented on this crystal for
displaying information on the board.
Besides this the board has RTC DS12CR887 real time clock, PHY Ethernet DP83848
physical layer, SDRAM Samsung K4S281632F-TC(L) and TI TUSB6250PFC chip
acting as a bridge for connecting storage devices with ATA/ATAPI interface for
connecting to USB 2.0.
