INTERLEAVED MEMORY Combining smaller memory modules into a single, larger memory is known as Interleaved Memory. Memory is typically not implemented as a single huge module (chip) in computer systems. Instead, it is created by memory interleaving a number of smaller modules together. Higher order and Lower order interleaving are two types of interleaving. HIGHER …
Paging in COA: Equal-sized blocks known as “Pages” are used to divide the virtual memory area. Equal-sized blocks known as Page Frames (also known as pages) are also used to split the Physical Memory space, also known as Main Memory. Virtual Memory pages are loaded into any free page frame in physical memory. For instance: Take …

instruction cycle instruction cycle in computer architecture what is instruction cycle Instruction cycle state Transition Diagram Instruction state transition diagram Steps in which the instruction is executed: 1) The PC provides the address to retrieve a memory instruction. 2) The instruction opcode is decoded after it has been fetched. 3) This indicates whether any operands …
Addressing modes in 8085 Addressing modes in 8085. The way in which an operand is given to an instruction is known as addressing mode. Addressing modes do exist in every processor and microcontroller, however they vary little. There are various types of addressing modes in 8051, and important ones are immediate addressing mode, register addressing mode, direct addressing …
