- 1. A PRESENTATION ON CPU (CENTRAL PROCESSING UNIT) Alaka Acharya 20C
- 2. CPU • Introduction • CPU Structure • Types of processors(Single and multi core) • Types of architecture(RISC and CISC) • Hyper threading and Turbo boosting technology • Computing/storage platforms
- 3. Introduction • The hardware that executes programs and manages rest of the computer system • Often known as ‘brains’ of the computer where most calculations take place. • First developed at Intel with in the early 1970's • This is intel 4004:
- 5. Types of processors: • Single core processors: • One core on a CPU chip • No so good at multi-tasking • Multi core processors: • More than one cores on a CPU chip • Each core executes a task independently • More efficient on multi-tasking • Multi core processors are widely used now-a-days
- 6. Types of processer architecture: • Reduced instruction set computer(RISC): • Uses simple instructions that can be divide into multiple instructions which perform low-level operation within single clock cycle • Complex instruction set computers(CISC): • Single instructions can execute several low-level operations or are capable of multi-step operations or addressing modes within single instructions
- 7. Types of processer architecture: • RISC vs. CISC CISC RISC Complex instructions Reduced instructions Sophisticated decoding Faster decoding Instructions take longer to execute Instructions take faster to execute Complex hardware requirement Simple hardware requirement PDP-11, VAX, Motorola 68k, Intel x86. Atmel AVR, PIC, ARM Decreases memory cost More memory required
- 8. • Hyper threading technology: • A processor with HTT consists of two logical processors(not actual) • Not the same as doubling core • Enables multiple threads to run on each core • Increases power consumption, heat output • Turbo-boosting technology: • Enables the processor to run above its rated operating frequency • Considers workload and operating environment. • Continuous turbo boost can decrease processor life
- 9. Computing/storage platforms • Cloud computing: • Internet based computing • Storing data and applications on remote servers and accessing them via the internet rather than saving on your hard drive • More scalable, reliable, secure and less expensive • Google drive, Microsoft onedrive, and even Facebook, YouTube are the examples. • Grid Computing • Distributed architecture of large numbers of computers connected to solve a complex problem. • Used for special projects, researches • OurGrid, World Computing Grid, TeraGrid
- 10. • Distributed computing: • Is to solve a single large problem by breaking it down into several tasks where each task is computed in the individual computers of the distributed system.
