The program counter ( PC ), [ 1] commonly called the instruction pointer ( IP) in Intel x86 and Itanium microprocessors, and sometimes called the instruction address register ( IAR ), [ 2][ 1] the instruction counter, [ 3] or just part of the instruction sequencer, [ 4] is a processor register that indicates where a computer is in its program ...
The program counter is typically set to a hard coded value when the CPU is first powered on, and will hence execute whatever machine code happens to be at this address. Similarly, the program counter can be set to execute whatever machine code is at some arbitrary address, even if this is not valid machine code. This will typically trigger an ...
In computing, code generation is part of the process chain of a compiler and converts intermediate representation of source code into a form (e.g., machine code) that can be readily executed by the target system. Sophisticated compilers typically perform multiple passes over various intermediate forms. This multi-stage process is used because ...
ELIZA. ELIZA is an early natural language processing computer program developed from 1964 to 1967 [ 1] at MIT by Joseph Weizenbaum. [ 2][ 3] Created to explore communication between humans and machines, ELIZA simulated conversation by using a pattern matching and substitution methodology that gave users an illusion of understanding on the part ...
Category. v. t. e. The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [ 2][ 3] It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator. [ 4]
Register machine. In mathematical logic and theoretical computer science, a register machine is a generic class of abstract machines, analogous to a Turing machine and thus Turing complete. Unlike a Turing machine that uses a tape and head, a register machine utilizes multiple uniquely addressed registers to store non-negative integers.
In computing, code generation denotes software techniques or systems that generate program code which may then be used independently of the generator system in a runtime environment. Specific articles: Code generation (compiler), a mechanism to produce the executable form of computer programs, such as machine code, in some automatic manner
The intermediate representation is a simple sequence of operations which can be used by an optimizer and a code generator which produces instructions in the machine language of the target processor. Because the code generator uses an intermediate representation, the same code generator can be used for many different high-level languages.
