Code segment (CS) is a 16-bit register containing address of 64 KB segment with processor instructions. The processor uses CS segment for all accesses to instructions referenced by instruction pointer (IP) register. CS register cannot be changed directly. The CS register is automatically updated during far jump, far call and far return instructions.
In computer architecture, a processor register is a quickly accessible location available to a computer’s central processing unit (CPU). Registers usually consist of a small amount of fast storage, although some registers have specific hardware functions, and may be read-only or write-only. Registers are normally measured by the number of bits they can hold, for example, an “8-bit register”, “32-bit register” or a “64-bit register” (or even with more bits).
Purpose of using Instruction Queue: BIU contains an instruction queue. When the EU executes instructions, the BIU gets up to 6 bytes of the next instruction and stores them in the instruction queue and this process is called instruction prefetch. This is a process to speed up the processor. A subtle advantage of instruction queue …
Internal architecture of 8086 microprocessor If we study the internal architecture of 8086 microprocessor, we can see that it has two major units; Execution Unit (EU) and Bus Interface Unit (BIU). They are dependent and work with each other. In the following given figure, which is a block diagram of 8086 microprocessor, it can be …
The Intel 8086, also called the iAPX 86, is a 16-bit microprocessor designed by Intel corporation between 1976-1978. This Intel 8086 microprocessor gave rise to the x86 architecture or 16-bit architecture. The figure given below is the internal architecture of Intel 8086 microprocessor
Problem: Binary Tree is Sum tree or Not. [Problem Link] Explanation: Write a function which returns True if the given binary tree is a Sum Tree, else False. A sum tree a is a binary tree where the value of a node is the summation of the subtree at both its left and right. An …
