The IC is capable of interpreting and executing program instructions and performing arithmetic operations. [1] The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results (also in binary form ...
The instructions were stored on replaceable program boards with a grid of bit positions. One (1) bits were represented by small metal squares that were sensed by amplifiers, zero (0) bits by the absence of the squares. [35] The system could be configured with up to 4K 16-bit words of microstore.
In computing, the instruction register (IR) or current instruction register (CIR) is the part of a CPU's control unit that holds the instruction currently being executed or decoded. [1]
The program counter points to a memory address and is changed based on special instructions which may cause programmatic branches. 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.
In computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions ...
An instruction set simulator (ISS) is a simulation model, usually coded in a high-level programming language, which mimics the behavior of a mainframe or microprocessor by "reading" instructions and maintaining internal variables which represent the processor's registers.
IC programming [1] is the process of transferring a software or firmware into an integrated circuit (IC), typically to enable the chip to perform specific tasks or functions. The process of IC programming usually requires an IC programmer, also known as a chip programmer, device programmer, or PROM writer, which is an electronic device used to ...
On a microprogrammed computer the microprogram implements the operations of the instruction set in which any normal program (including both application programs and operating systems) is written. The use of a microprogram allows the manufacturer to fix certain mistakes, including working around hardware design errors, without modifying the ...
