(that may be 8, 16 or 32 bits wide) that sends an address to memory

Address Bus

(that may be 8. 16 or 32 bits wide) that can send data to memory or receive data from memory

Data Bus

to tell the memory whether it wants to set or get the addressed location

RD (Read) and WR (Write) line

that lets a clock pulse sequence the processor

clock line

that resets the program counter to zero (or whatever) and restarts execution.

enable it to function as a programmable logic processor

Logical components

provide for the management of a program

Program counter, stack, and instruction register

-provide for the manipulation of data

ALU

-specify and coordinate the operation of other components

Decoder & timing and control unit

The connection of the microprocessors to other units-memory and 1/0 devices-is done with the

Address, Data, and Control buses

A typical microprocessor, therefore, consists of:

•Logical Components •Program counter, stack, and instruction register •ALU •Decoder and timing and control unit

microprocessors that were introduced in 1971 to 1972 were referred to as the

first generation systems

True or False: First-generation microprocessors processed their instructions serially -they fetched the instruction, decoded it, then executed it

True

This generation is defined by overlapped fetch, decode, and execute steps

Second Generation

By the late __________, enough transistors were available on the IC to usher in the second generation of microprocessor sophistication: 16 bit arithmetic and pipelined instruction processing.

1970s

Second Generation example

Motorola's MC68000 microprocessor introduced in 1979 Intel's 8080

True or False In second Generation, as the first instruction is processed in the execution unit, the second instruction is decoded and the third instruction is fetched.

True

The distinction between the first-and second-generation devices was primarily the use of newer _____________ technology to fabricate the chips

semiconductor

In second generation, this new technology resulted in a five-fold increase in

instruction, execution, speed, and higher chip densities.

The third generation, introduced in _________, was represented by _________ and ____________, which were _____________ with minicomputer-like performance.

1978 Intel's 8086 and the Zilog Z8000 16-bit processors

The third generation came about as IC transistor counts approached ________.

250,000

In third generation, _____________, for example, incorporated an on-chip cache for the first time and the depth of the pipeline increased to five or more stages.

Motorola's MC68020

This generation of microprocessors was different from the previous ones in that all major workstation manufacturers began developing their own RISC-based microprocessor architectures

Third Generation

As the workstation companies converted from commercial microprocessors to in-house designs, microprocessors entered their ______________ with designs surpassing a million transistors.

Fourth Generation

In fourth generation, Leading- edge microprocessors such as ___________ and _____________ could issue and retire more than one instruction per clock cycle.

Intel's 80960CA Motorola's 88100

Microprocessors in their ______________, employed decoupled super scalar processing, and their design soon surpassed 10 million transistors.

Fifth Generation

In this generation, PCs are a low-margin, high-volume-business dominated by a single microprocessor
