Specific embodiment
Be described further below technical scheme, but claimed scope be not limited to described.
A kind of embedded home gateway as shown in Figure 1, including microprocessor, flash storage, SDRAM, ether web-roll core
Piece, serial line interface；The microprocessor adopts 32 process chips of ARM frameworks；The flash storage, SDRAM, Ethernet
Chip, serial line interface are connected to microprocessor；The flash storage, for storage program area, http server, CGI
Gateway application, home network server；Operating system adopts uClinux；The serial line interface is bi-directional transceiver；Described
Ethernet chip connects external network, and serial line interface connects Intranet equipment.
The Ethernet chip adopts DM916.
The SDRAM is that two panels HY57V641620 is in parallel.
Flash storage HY29LV160 of the flash storage for 2M.
S3C4510B chip of the microprocessor using Samsung companies.
The serial line interface adopts two panels MAX232 chip.
The connection bus of the microprocessor, using 74LVC4245 as bus driver and level conversion.
The http server facing external network offering services, the home network server are provided towards Intranet equipment
Service, the CGI gateway applications are responsible for connecting http server and home network server.
Thus：
1. microprocessor：The reasons such as power consumption, cost are considered, selection is the production of ARM framework Samsung companies
S3C4510B chips, its kernel are the general 32 ARM7TDMI microprocessor cores designed by ARM companies.
2. flash storage：Should for storing the embedded OS in home gateway, http server, CGI gateways
With the file system needed for program, home network server, and the various services of support.During system start-up, will transport from Flash
Row Boot loader, decompression operation system simultaneously will be moved in SDRAM.For meeting the storage needs of system, select 2M's
Flash storage HY29LV160 is used as storage medium.
③SDRAM：Actual demand is considered, from the two panels HY57V641620 SDRAM memory system for building 32 in parallel
System, the SDRAM spaces of common 16MB.
4. bus driving circuits：Because the system bus drive ability of ARM microprocessor relatively weak, and in view of bus
Level conversion problem, the system is using 74LVC4245 as bus driver and level conversion.
5. 10Mbps/100Mbps Ethernets：S3C4510 chip internals are integrated with ethernet mac control, but do not provide
Physical layer interface, needs external a piece of physical chip to provide the access passage of Ethernet, from DM916.
6. serial line interface：S3C4510B supports two asynchronous serial ports, completes the transmitting-receiving of serial data, one of them
UART ports are used for the virtual console of host and the information exchange of Target Board.Connect as serial data transmitting-receiving from MAX232
Mouthful, it is the requirement for meeting the transmission of home network view data, in gateway designs, needs the asynchronous serial with hardware flow-control
Communication.Therefore, the level of the data and hardware flow control signal that complete two UART interfaces from two panels MAX232 chip turns
Change.
7. general purpose I/O：S3C4510B chips support 18 general purpose I/O, in addition to demultiplexing I/O mouths, have P0-P7 totally 8 I/
O, they are used for accessing external status signals or drive state LED of debugging.8 special I/O mouths that S3C4510 is supported are straight
Driving LED is met, is used as test.
8. other peripheral drive circuits needed for S3C4510B：Peripheral circuit needed for S3C4510B includes：Power circuit,
Real-time clock interface circuit (50MHz), switch and reset circuit, JATG interface circuits and keyboard interface circuit.
As shown in Fig. 2
1. embedded HTTP server：For realizing that the various functions of home gateway, http server must be assisted according to HTTP
The specification of view and client interact, and involve how to set up connection with client, explain the request message of client, according to client's
Require to execute corresponding process, and result is returned to client etc. as response message using which kind of syntax format and ask
Topic.
2. Web server：Gateway application connection http server and HomeNetServer, in the dynamic of remotely control
Undertaking effect is played in state interaction, therefore, the design of gateway application is most important to the performance of server.
