The Application And Study Of SoC In Embedded Systems Design Base On FPSLIC

Soc (System on Chip) is a kind of computer System which is integrated stimulant IP core ,digital IP core and memorizer on one chip. Currently, it is very popular that apply SoC chip on design of embedded system , in addition ,it's also the main way in the design of embedded system in the future.This paper will present a high speed data sampling system based on the Atmel FPSLIC (Field Programmable System Level Integrated Circuit) device. The FPSLIC provides a unique hardware/software platform that allows system functions to be implemented in either hardware or software as requirements dictate and provides for easy and fast communication between the two during system operation. Furthermore, the level of integration of the FPSLIC device makes for a low-power, compact system solution that fits well within the requirements for high speed data sampling system.The ATMEL FPSLIC device combines an 8-bit AVR microcontroller with 32K bytes of SRAM and a 40K gate equivalent FPGA device on a single chip. Atmel provides the System Designer software for developing applications based on the FPSLIC. System Designer includes a comprehensive FPGA tool suite based on the Exemplar HDL Synthesis tool and Figaro Place and Route tools for developing hardware to be implemented in the on-chip FPGA. For software development, System Designer includes an AVR Instruction Set Simulator and the AVRStudio development and debugging environment. The architecture of high speed data sampling system makes effective use of the FPSLIC device by mapping some functions to dedicated hardware in the FPGA portion of the FPSLIC, and other functions to software executing on the AVR microcontroller inside the FPSLIC . The main operation can be implemented in the AVR core and the data sampling control can be functioned in the port of FPGA it with HDL language. In summary, it is feasibly and technically ,can easily implemented the system.
