Tiny SBC runs uClinux from Altera soft-core RISC CPU
Feb 11, 2004 — by LinuxDevices Staff — from the LinuxDevices Archive — 20 viewsSSV Embedded Systems has launched a new model in its tiny DIL/NetPC single-board computer (SBC) line that runs uClinux out of a 32-bit NIOS “soft-core” RISC processor in an Altera FPGA (Field Programmable Gate Array) instead of a hard-wired microprocessor. According to SSV, the module is ideal for Ethernet-enabled devices requiring very long product lifecycles.

SSV lists the following features and specs for the uClinux-based module:
- Altera 32-bit NIOS RISC Softcore with 512 internal Registers
- 50 MHz Operation
- 16 MByte SDRAM Memory with 32-bit Data Path
- 8 MByte Flash Memory with 16-bit Data Path
- 10/100 Mbps Ethernet LAN Interface
- Two asynchronous Serial Ports (one with Handshakes)
- 20-bit General Purpose high-speed Parallel I/O
- 16-bit ISA-like Expansion Bus
- IDE Interface with CompactFlash Support (True IDE Mode)
- Seven Interrupt Inputs
- Four Chip Select Outputs
- Programmable General Purpose Timers and Watchdog Timer
- JTAG IEEE 1149.1 Test Interface
- In-System Programming Features
- 128-pin QIL (Quad-In-Line) Connector, 2.54mm Centers
- 3.3 Volt Low Power Design, Supply Voltage 3.3 VDC (+- 5%)
- Supply Current 450 mA typ. at 50 MHz
- Size 82mm x 33mm
SSV offers a starter kit for the module that includes a networking and prototyping board, and several sample applications. uClinux is included as the embedded operating system, based on a 2.4 kernel. The operating system can be stored in Flash together with the TCP/IP protocol stack and the webserver, telnet daemon, and (T)FTP-server.
