Pin Diagram of Pentium Processor: The Pentium's memory and I/O interfaces are more advanced than the simple models. They are very different from the 8086 bus interfaces. Figure 12.28(a) shows the Pentium processor and the…

Virtual 8086 Mode in Microprocessor: The virtual 8086 mode is a special operating mode of the Pentium processor and it is a subset of protected mode. In this mode, two 8086 application programs can be…

Linear, Logical Address and Physical Address in Microprocessor: The Linear, Logical Address and Physical Address in Microprocessor is given below Physical Address In protected mode, the Intel Architecture (IA) 32-bit processors/Pentium processors provide a usual…

What is Segmentation in Pentium Processor? What is Segmentation in Pentium Processor? - When segmentation is used in memory management of the Pentium processor, the processor's linear address space is broken up into a set…

Operating Modes of Pentium Processor: The Pentium processor architecture supports three Operating Modes of Pentium Processor such as protected mode, real-address mode and System Management Mode (SMM) and one 'quasi-operating mode' or virtual-8086 mode. In…

Internal Architecture of Pentium Processor: The Pentium is a 32-bit processor, but it has a 32-bit address bus and a 64-bit data bus. This processor's data bus serves the on-chip caches, but not the 32-bit…

Pin Diagram of 80486 Microprocessor: The pin diagram of 168-pin PGA (Pin Grid Array) package 80486 is shown in Fig. 11.49 and the schematic Pin Diagram of 80486 Microprocessor is depicted in Fig. 11.50. All…

Architecture of 80486 Microprocessor: The 80486DX is a 32-bit processor. Figure 11.46 shows the simplified block diagram of 80486 and the inter­nal architecture of 80486 Microprocessor is depicted in Fig. 11.47. The architecture of Intel's…
