Since issuing the HLT instruction requires ring 0 access, it can only be run by privileged system software such as the kernel. Because of this, it is often best practice in application programming to use the application programming interface (API) provided for that purpose by the operating system when no more work can be done, such as Linux's ...
The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. [2] It is the last 8-bit microprocessor developed by Intel. It is software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.
Minimalistic support for three assembler directives (.equ, .db, .ds) to control data locations, there exist no directives to directly control code locations Code start is defined outside source code ("load me at" entry) - if not defined (default), code is generated (strangely) from 4200h (instead from the real reset vector 0000h)
Verify a segment for reading. Sets ZF=1 if segment can be read, ZF=0 otherwise. VERW r/m16: 0F 00 /5: Verify a segment for writing. Sets ZF=1 if segment can be written, ZF=0 otherwise. [k] LOADALL [l] 0F 05: Load all CPU registers from a 102-byte data structure starting at physical address 800h, including "hidden" part of segment descriptor ...
The x86 instruction set has several times been extended with SIMD (Single instruction, multiple data) instruction set extensions.These extensions, starting from the MMX instruction set extension introduced with Pentium MMX in 1997, typically define sets of wide registers and instructions that subdivide these registers into fixed-size lanes and perform a computation for each lane in parallel.
D3 doing nothing, has been halted by the HLT instruction; D4 writing data to an output port; D5 reading the first byte of an executable instruction; D6 reading data from an input port; D7 reading data from memory; 4: D5 5: D6 6: D7 7: D3 8: D2 9: D1 10: D0 11: −5 V — The −5 V power supply.
The instruction set architecture (ISA) that the computer final version (SAP-3) is designed to implement is patterned after and upward compatible with the ISA of the Intel 8080/8085 microprocessor family. Therefore, the instructions implemented in the three SAP computer variations are, in each case, a subset of the 8080/8085 instructions.
