Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 Embedded Systems role in the High-Tech world is growing. New embedded systems require a larger amount of flexibility, computation power and reliable I/O devices. This goal can be achieved by using Multi-Processor System with an explicit distribution of tasks. This way one CPU handles I/O tasks, and the other handles calculation tasks. Altera’s Nios embedded processor is a user-configurable, general-purpose RISC embedded processor. Gidel’s development board with an Altera FPGA is a suitable platform for combining System On Chip with peripheral devices.

System description המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 3 The system that was build in this project achieves the following goals: Combining Ethernet card with embedded system on Gidel development PCI board. Building Multi-Processor SOC (System On Chip) that consists of two Nios processors with an explicit distribution of tasks:  CPU that handles I/O tasks through Ethernet connection.  CPU that handles extensive calculation tasks. Sharing a common external SDRAM by both Nios CPUs. Writing a software application that demonstrates the concurrent functionality of the system. Building a platform for rapid development of the embedded system on Gidel PCI card using Altera Nios technology.
