Discuss All Tybes Of Intel & AMD processors

2. The Central Processing Unit (CPU)
or the processor
Is the portion of a computer system that carries out the instructions of a
computer program, and is the primary element carrying out the computer's
functions. This term has been in use in the computer industry at least since
the early 1960s [1]. The form, design and implementation of CPUs have
changed dramatically since the earliest examples, but their fundamental
operation remains much the same.

3. Discrete transistor and Integrated
Circuit CPUs:
integrated circuit (IC) allowed a large number of transistors to be
manufactured on a single semiconductor -based die, or "chip." At first only
very basic non -specialized digital circuits such as NOR gates were
miniaturized into ICs. CPUs based upon these "building block" ICs are
generally referred to as "small-scale integration" (SSI) devices. SSI ICs, such
as
the ones used in the Apollo guidance computer

4. microelectronic technology
advanced, an increasing number of transistors were placed on ICs, thus
decreasing the quantity of individual ICs needed for a complete CPU.
MSI and LSI (medium- and large-scale integration) ICs increased transistor
counts to hundreds, and then thousands

5. Processor register
In computer architecture , a processor register (or general purpose register ) is a small
amount of storage available on the CPU whose contents can be accessed more quickly than
storage available elsewhere.
Most, but not all, modern computers adopt the so-called load-store architecture
. A common property of computer programs is locality of reference: the same values are
often accessed repeatedly; and holding these frequently used values in registers improves
program execution performance.
Processor registers are at the top of the memory hierarchy, and provide the fastest way for
a CPU to access data. The term is often used to refer only to the group of registers that are
directly encoded as part of an instruction, as defined by the instruction set.

6. The table shows the number of
registers of several mainstream
architectures

7. The Process
•Process is a program in execution .a process is more
than the program code which is known sometimes as a
text section.
•It also includes the current activity, as represented by
the value of the program counter & the contents of the
processor's registers.
•Process generally includes the process stack,which
contains temporary data (such as method parameters
,return addresses,local variables),and data section,which
contains global variables.

8. The Process
•We emphasize that a program by itself is not a process;
a program a passive entity, such as the contents of a file
stored on disk, whereas a process is an active entity ,
with a program counter specifying the next instruction to
execute and a set of associated resources.

9. Process State
•As a process executes ,it changes state .The State of a
process is defined in part by the current activity of the
process. Each process may be in one of the following
states :
1 . New : The process is being created.
2 . running: Instructions are been executed.
3 .waiting: The process is waiting for some event to occur(such as
an I/O completion or reception of a signal).
4 . Reading: The process is waiting to be assigned to a processor.
5 .Terminated: The process has finished execution .

10. Process Control Block:
A Process Control Block (PCB,
also called Task Controlling
Block or Task Struct) is a data
structure in the operating
system kernel containing the
information needed to manage
a particular process. The PCB is
"the manifestation of a
process in an operating
system".

11. Included information :
The identifier of the process ( process identifier , or PID )
Register values for the process including, notably, the program counter and
stack pointer values for the process.
The address space for the process
Priority (in which higher priority process gets first preference. e.g., nice value on
Unix operating systems)
Process accounting information, such as when the process was last run, how
much CPU time it has accumulated, etc.
Pointer to the next PCB i.e. pointer to the PCB of the next process to run
I/O Information (i.e. I/O devices allocated to this process, list of opened files,
etc.)

12. CPU switches from process to
process:

13. Location of the PCB
Since PCB contains the critical
information for the process, it
must be kept in an area of
memory protected from normal
user access. In some operating
systems the PCB is placed in the
beginning of the kernel stack of
the process since that is a
convenient protected location .

14. Threads:
The implementation of
threads and processes differs
from one operating system
to another, but in most
cases, a thread is contained
inside a process. Multiple
threads can exist within the
same process and share
resources such as memory,
while different processes do
not share these resources

15. Process scheduling:
Scheduling refers to the way
processes are assigned to run
on the available CPUs, since
there are typically many
more processes running than
there are available CPUs. This
assignment is carried out by
soft wares known as a
scheduler and dispatcher.

16. Scheduling Queue:
Job queue – set of all processes
in the system.
Ready queue – set of all
processes residing in main
memory, ready and waiting to
execute.
Device queues – set of
processes waiting for an I/O
device.
Process migration between the
various queues.

18. The history of the ARM processors from their beginnings as the proprietary solution for a particular
set of problems in a particular company to their current status as a highly successful, flexible and
customizable set of processors available on the open market.
Founded in November 1990.Spun out of Acorn Computers.
Designs the ARM range of RISC processor cores.
Also develop technologies to assist with the design -in of the ARM
architecture.
Software tools, boards, debug hardware, application software, bus architectures, peripherals etc.

21. High performance for low price
The original ARM1 device was intended to power an Acorn computer.
Short design time
One of ARM Ltd's stated goals is to provide a quick and effective design
service to produce custom processors based on ARM macrocells.
High performance for low power consumption
A further advantage of the small size of ARM devices is that they do not
consume as much power as other, larger processors.
Easily customized designs
The above factors combine to make the ARM product range extremely
flexible. The small size of the ARM processor means that it can easily be
combined with its support chips, cache memory, or custom circuitry to make
self-contained custom chips. All ARM devices are designed as macrocells,
building blocks which can be combined within a single chip.

22. The ARM is a 32-bit architecture.
When used in relation to the ARM:
Byte means 8 bits
Halfword means 16 bits (two bytes)
Word means 32 bits (four bytes)
Most ARM’s implement two instruction sets
32-bit ARM Instruction Set
16-bit Thumb Instruction Set
Jazelle cores can also execute Java bytecode

23. The ARM has seven basic operating modes:
User : unprivileged mode under which most tasks run
FIQ : entered when a high priority (fast) interrupt is raised
IRQ : entered when a low priority (normal) interrupt is raised
Supervisor : entered on reset and when a Software Interrupt instruction is executed
Abort : used to handle memory access violations
Undef : used to handle undefined instructions
System : privileged mode using the same registers as user mode

25. 1 dedicated program counter
1 dedicated current program status register
5 dedicated saved program status registers
30 general purpose registers
The current processor mode governs which of several banks is
accessible. Each mode can access
a particular set of r0-r12 registers
a particular r13 (the stack pointer, sp) and r14 (the link register,
lr)
the program counter, r15 (pc)
the current program status register, cpsr
Privileged modes (except System) can also access
a particular spsr (saved program status register)
