Difference Between RISC and CISC Processors Slno Similarities 1. Both are Processor’s architecture that are predominantly used today. 2. 3. Slno RISC CISC 1. Stands for ‘Reduced Instruction Set Computers’ Stands for ‘Complex Instruction Set Computers’. 2. Each instruction utilizes comparatively less number of Instruction cycle before completion of a Read more…
VLSI (Very Large Scale Integration)Technology VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. Carver Mead is an inventor, chip designer, entrepreneur, and university physicist. Mead. It was founded in 1979 and head quarter is California USA. VLSI is a modern and advanced technology for chip Read more…
Introduction Assembly language programming is the first step to improving the programming structure. As we know that machine language is very difficult to understand when a program or instruction is written in machine language. Therefore, each manufacturer of a microprocessor has developed a symbolic code for each education called a Read more…
Introduction A computer instruction is made up of an operation code (op-code) followed by either zero, one or two bytes of operands. Definition Instruction An instruction is a signal(command) in the form of sequence of 0s and 1s(machine language) that is given to a computer’s processor(microprocessor) to do some specific Read more…
Introduction An operation code(opcode) of an instruction specifies the operation to be performed on data. This operation is mainly executed on some data stored in register or memory. Operands may be specified in one of the three basic forms i.e., immediate, register, and memory. Conventions: In this addressing scheme, the Read more…
Introduction CPU organization is the arrangement of CPU components in systematic order to work efficiently. Characteristics As we know that a computer manipulates data according to the given instructions using stored program concept. Here, stored program concept means the program and data are stored in the same memory unit. The Read more…
Introduction A control unit is a complex circuitry structure within a computer’s processor that directs, dictates and coordinates the overall operations of the computer to run it smoothly and successfully. Definition The Control Unit(CU) is one of the basic/major component of the processor/CPU which controls and coordinates the various operations Read more…
Introduction An arithmetic logic unit (ALU) is a very important part of a CPU. Definition An arithmetic logic unit (ALU) is an execution unit and important part of a CPU that does simple as well as complex arithmetic, logic and shift operations in the form of binary arithmetic and boolean Read more…
Introduction In computer architecture, a processor register is a very fast computer memory used to speed up the execution of computer programs by providing quick access to commonly used values. A register is a word of internal/CPU memory like the accumulator. The most early machines used stack or accumulator type of architectures to manipulate data but these days all CPUs made are Read more…
