CPU HISTORY MUKUND
The document traces the evolution of Intel microprocessors from 1971 to 1997, highlighting several major milestones. It describes the 4004 as Intel's first microprocessor in 1971. The 8080 became the central processing unit of the first personal computer, the Altair, in 1974. The 8086 and 8088, released in 1978 and 1979 respectively, established Intel in the personal computer market. Subsequent processors like the 286, 386, 486, and Pentium lines further increased processing power and capabilities.
DMA operation
1. Direct Memory Access (DMA) allows input/output devices to directly access main memory, bypassing the CPU to speed up memory transfers. This is managed by a DMA controller.
2. During a DMA transfer, the DMA controller gains control of the address bus, data bus, and control bus from the microprocessor to transfer data directly between an I/O port and memory.
3. The DMA controller has several options for transferring data, including cycle stealing for single byte transfers, burst mode for block transfers using address sequencing, and hidden DMA which occurs transparently when the CPU is not using the bus.
03 Buses
The document discusses computer system buses and their role in connecting central processing units to memory and input/output devices. Buses transfer data, addresses, and control signals between components. Common bus types include data buses to transfer data, address buses to specify memory locations, and control buses that coordinate timing. Interrupt signals can suspend normal processing to handle higher priority events. Modern buses like PCI use arbitration to allow shared access among devices.
8085 addressing modes
The document discusses the addressing modes used by the Intel 8085 microprocessor. It explains that an instruction specifies an operation along with the source and destination addresses. The Intel 8085 supports 5 addressing modes: direct, register, register indirect, immediate, and implicit. Each mode is defined by how the source or destination operand address is specified in the instruction.
Comparison of pentium processor with 80386 and 80486

The 80486 provided improvements like an 8KB cache and integrated floating point unit.

2. Each counter can be programmed to count from 1 to 65535 and has a programmable control word to select the operating mode.
3. The 8254 supports various timer modes like one-shot, continuous square wave, event counter, and software/hardware triggered one-shot for applications like timing, delay generation, and pulse width modulation.
1327 Addressing Modes Of 8086

Types Of Buses
The document discusses several computer bus architectures used to connect components internally in a computer system, including ISA, EISA, VESA Local Bus (VLB), PCI, PCI-X, PCI Express, and RS-232. The ISA bus was introduced in 1981 as a 16-bit standard but has been replaced by newer standards capable of higher data transfer speeds such as 32-bit EISA, VLB, and PCI, as well as serial standards PCI Express and USB. Each new standard aimed to offer improvements in speed, functionality and compatibility over older designs.

In minimum mode, the 8086 generates its own control signals to interface with memory and I/O, while in maximum mode it requires an 8288 bus controller to generate the control signals. Minimum mode has limitations and does not support the 8087 coprocessor, while maximum mode allows use of the coprocessor and provides additional functions. Key signals in minimum mode include the address/data bus lines, status lines, control signals like ALE and M/IO, and interrupt lines.
8086 microprocessor
The 8086 microprocessor is a 16-bit processor with a 20-bit address bus that can access up to 1MB of memory. It has 14 general purpose 16-bit registers and operates in minimum and maximum modes. In minimum mode, the 8086 provides all control signals for memory and I/O interfacing, including address/data bus lines, status lines, and control signals to indicate read/write operations and memory versus I/O access.
Direct Memory Access(DMA)
Direct Memory Access (DMA) allows certain hardware subsystems to access main system memory independently of the CPU. DMA controllers temporarily borrow the address, data, and control buses from the microprocessor to transfer data directly between an I/O port and memory locations. This allows fast transfer of data to and from devices while the CPU performs other tasks, improving overall system performance. DMA transfers can occur via block transfers where the DMA controller controls the bus for an extended period, or via cycle stealing where it uses the bus for one transfer then returns control to the CPU.
Addressing Modes Of 8086
The document discusses the different addressing modes of the 8086 processor. It explains that addressing modes refer to the different ways a processor can access data. It then describes the 8 addressing modes of the 8086 - immediate, direct, register, register indirect, indexed, register relative, based indexed, and relative based indexed. For each mode, it provides an example of how the MOV instruction is used with that addressing mode and how the physical address is calculated.
Pentium processor
The Pentium processor introduced in 1993 features a superscalar architecture that allows multiple instructions to be executed simultaneously. It has separate 8KB instruction and data caches and a 64-bit data bus. The Pentium uses dynamic branch prediction and out-of-order execution to further improve performance through superscalar design.
INTERRUPTS OF 8086 MICROPROCESSOR
The document discusses interrupts in computing systems. It defines an interrupt as either a hardware-generated call from an external signal or a software-generated call from an instruction. The main purposes of interrupts are to halt normal program execution and divert processing to an interrupt service routine in response to external events. It then provides details on different types of interrupts, including hardware interrupts from devices and software interrupts from instructions. It lists and describes the most common interrupt types and their associated vector numbers.

This document describes troubleshooting three network connectivity problems at OCP Enterprises. Problem 1 was that PC1 could not reach PC4, which was caused by R2 missing a route to network 1 in its routing table. Problem 2, that PC1 could not reach devices on network 3, was also due to this missing route. Problem 3, that only PC1 and PC3 but not PC2 could reach network 3, was found to be due to PC2 having an incorrect default gateway and IP address configuration.
