Аннотация

This paper describes the design of a fully integrated PC-architecture SoC for industrial control which is capable of executing DOS and X86-compatible binary applications. It is a high performance and cost-effective SoC and meets the needs of embedded applications. The SoC provides 2 UARTs, 1 ECP/EPP parallel port, PC104 bus interface, 15 interrupt requests, 3 DMA requests, 3 timers, and 1 watchdog timer. Further, it supports up to 64 MB SDRAM, 32 MB solid state disk. The SOC integrates a self-designed 486DX4 compatible microprocessor, system control logic, SDRAM controller and peripheral control logic. It was designed using 0.18 mum CMOS standard cell library and consists of about 780 K gates, 10 KB SRAM and 350 Kbits ROM. It works at 133 MHz frequency, with less than 2 W power consumption.
