emulate a Cisco IOS on PC

互联网 | 编辑: 2006-09-04 00:00:00转载
the emulator I have programmed is able to boot a large number of Cisco IOS releases available for the 7200 platform, including the latest 12.2S and 12.4.

The following devices a re emulated in the current release:

MIPS64 CPU processor. The instruction set is not completely emulated now (FPU support is lacking, TLB support is not finished and other minor things), but it is sufficient for IOS ;
DRAM and Packet SRAM memory ;
Non-Volatile Memory (NVRAM) ;
Signetics SCN 2681 DUART (Console and AUX ports);
Dallas DS1620 Temperature Sensors and Voltage Sensors, allowing the Environmental Monitor to work properly ;
NMC93C46 Serial EEPROM ;
Bootflash of 8 Mb (Intel 28F016SA) ;
I/O and Midplane FPGA specific to the C7200 platform ;
Basic Galileo GT64010/GT64120 PCI controller, DEC 21x50 PCI bridges and so.
Ethernet cards "C7200-IO-FE" and "PA-FE-TX" based on DEC21140 chip ;
ATM card "PA-A1" based on Texas Instruments Tneta1570 chip ;
