Processor types

  1. 1. The Central Processing Unit (CPU) or the processorIs the portion of a computer system that carries out the instructions of acomputer program, and is the primary element carrying out the computersfunctions. This term has been in use in the computer industry at least sincethe early 1960s [1]. The form, design and implementation of CPUs havechanged dramatically since the earliest examples, but their fundamentaloperation remains much the same.
  2. 2. Discrete transistor and Integrated Circuit CPUs:integrated circuit (IC) allowed a large number of transistors to bemanufactured on a single semiconductor -based die, or "chip." At first onlyvery basic non -specialized digital circuits such as NOR gates wereminiaturized into ICs. CPUs based upon these "building block" ICs aregenerally referred to as "small-scale integration" (SSI) devices. SSI ICs, suchasthe ones used in the Apollo guidance computer
  3. 3. microelectronic technologyadvanced, an increasing number of transistors were placed on ICs, thusdecreasing the quantity of individual ICs needed for a complete CPU.MSI and LSI (medium- and large-scale integration) ICs increased transistorcounts to hundreds, and then thousands
  4. 4. Processor registerIn computer architecture , a processor register (or general purpose register ) is a smallamount of storage available on the CPU whose contents can be accessed more quickly thanstorage 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 areoften accessed repeatedly; and holding these frequently used values in registers improvesprogram execution performance.Processor registers are at the top of the memory hierarchy, and provide the fastest way fora CPU to access data. The term is often used to refer only to the group of registers that aredirectly encoded as part of an instruction, as defined by the instruction set.
  5. 5. The table shows the number ofregisters of several mainstream architectures
  6. 6. The Process•Process is a program in execution .a process is morethan the program code which is known sometimes as atext section.•It also includes the current activity, as represented bythe value of the program counter & the contents of theprocessors registers.•Process generally includes the process stack,whichcontains temporary data (such as method parameters,return addresses,local variables),and data section,whichcontains global variables.
  7. 7. The Process•We emphasize that a program by itself is not a process;a program a passive entity, such as the contents of a filestored on disk, whereas a process is an active entity ,with a program counter specifying the next instruction toexecute and a set of associated resources.
  8. 8. Process State•As a process executes ,it changes state .The State of aprocess is defined in part by the current activity of theprocess. Each process may be in one of the followingstates :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 asan 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 .
  9. 9. Process Control Block:A Process Control Block (PCB,also called Task ControllingBlock or Task Struct) is a datastructure in the operatingsystem kernel containing theinformation needed to managea particular process. The PCB is"the manifestation of aprocess in an operatingsystem".
  10. 10. Included information :The identifier of the process ( process identifier , or PID )Register values for the process including, notably, the program counter andstack pointer values for the process.The address space for the processPriority (in which higher priority process gets first preference. e.g., nice value onUnix operating systems)Process accounting information, such as when the process was last run, howmuch CPU time it has accumulated, etc.Pointer to the next PCB i.e. pointer to the PCB of the next process to runI/O Information (i.e. I/O devices allocated to this process, list of opened files,etc.)
  11. 11. CPU switches from process to process:
  12. 12. Location of the PCB Since PCB contains the criticalinformation for the process, itmust be kept in an area ofmemory protected from normaluser access. In some operatingsystems the PCB is placed in thebeginning of the kernel stack ofthe process since that is aconvenient protected location .
  13. 13. Threads: The implementation ofthreads and processes differsfrom one operating systemto another, but in mostcases, a thread is containedinside a process. Multiplethreads can exist within thesame process and shareresources such as memory,while different processes donot share these resources
  14. 14. Process scheduling:Scheduling refers to the wayprocesses are assigned to runon the available CPUs, sincethere are typically manymore processes running thanthere are available CPUs. Thisassignment is carried out bysoft wares known as ascheduler and dispatcher.
  15. 15. Scheduling Queue:Job queue – set of all processesin the system.Ready queue – set of allprocesses residing in mainmemory, ready and waiting toexecute.Device queues – set ofprocesses waiting for an I/Odevice.Process migration between thevarious queues.

  17. 17. 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 ARMarchitecture. Software tools, boards, debug hardware, application software, bus architectures, peripherals etc.

  19. 19. High performance for low priceThe original ARM1 device was intended to power an Acorn computer.Short design timeOne of ARM Ltds stated goals is to provide a quick and effective designservice to produce custom processors based on ARM macrocells.High performance for low power consumptionA further advantage of the small size of ARM devices is that they do notconsume as much power as other, larger processors.Easily customized designsThe above factors combine to make the ARM product range extremelyflexible. The small size of the ARM processor means that it can easily becombined with its support chips, cache memory, or custom circuitry to makeself-contained custom chips. All ARM devices are designed as macrocells,building blocks which can be combined within a single chip.
  20. 20. 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 SetJazelle cores can also execute Java bytecode
  21. 21. 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

  23. 23. 1 dedicated program counter 1 dedicated current program status register 5 dedicated saved program status registers 30 general purpose registersThe current processor mode governs which of several banks is accessible. Each mode can access a particular set of r0-r12 registersa 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)
