8086/8088 system structure of Microprocessor

I. Basic architecture of 8086/8088 Microprocessor Intel 8086 Microprocessor has 16-bit registers and 16-bit external data bus, 20-bit address bus, addressing 1 MB address space. The external data bus of Intel 8088 microprocessor is 8-bit, and the others are the same as those of 8086. Figure 1 8086 structure of the microprocessor It can be seen that the 8086 CPU

, test the results of signed integer operations (flags s,o and z).JE/JZ equals transfer.JNE/JNZ is not equal to the time shift.JC is shifted when carrying a carry.JNC is transferred without carrying.Jno does not overflow when transferred.Jnp/jpo parity is odd when transferred.JNS is shifted when the sign bit is "0".JO overflow transfer.Jp/jpe parity is even when transferred.The JS sign is shifted when the bit is "1".3> Cyclic control instruction (short transfer)Loop CX does not cycle at zero.Loo

Modify Wamp's Apache default port 80 to 8088 and the WWW directory _linux

For example, modify to 8088 port and d:/workphp directory. Modified to Port 8088 Left-tray icon, in the "Apache" can directly open httpd.conf, find "Listen 80", can be changed to other ports, I choose 8088. Restart the Wamp, it will be effective. But "Localhost", "phpMyAdmin", "Sqlitemanager", you can click to open to see still the default 80 port. Locate

Of course, the ESC directive does not allow im

The name and function of the flag of register F of 8086/8088

Cf -- carry flag ). If cf = 1, carry or borrow digits are generated during arithmetic operations. Otherwise, cf = 0. The shift instruction affects cf. PF -- parity flag (parity flag ). If pF = 1, the number of "1" in the operation result is an even number. Otherwise, pF = 0. This flag is mainly used to check errors during data transmission. Af-secondary carry flag (Auxiliary carry flag ). If AF = 1, the byte operation generates carry or borrow bits for the lower half-byte to the higher half-by

CPU load suddenly increased under Linux, but top does not see a high CPU consuming process, how to find out what process CPU is occupied?

The program is written by PHP a websocket server, the client is connected to send messages continuously, the service side is responsible for responding to requests. Tested: Once per request of client, server PHP consumes time of Microsecs to MICROSECS (message size is different). The server is a single core, 30 clients, using top to view PHP processes occupy CPU around 3-5%, load average 1 minutes load display 0.05 or so. Basically meet expectations.
