Specialized parallel computing
- 2. Table of contents: 1. What’s a specialized parallel computer. 2. Reconfigurable computing with field- programmable gate arrays (FPGA). 3. General-purpose computing on graphics processing units (GPGPU). 4. Application-specific integrated circuits. 5. Vector processors.
- 3. What’s a specialized parallel computer? Within parallel computing, there are specialized parallel devices, that tend to be applicable to only a few classes of parallel problems.
- 4. Specialized parallel computer architectures, are sometimes used alongside traditional processors, for accelerating specific tasks.
- 5. Reconfigurable computing with field- programmable gate arrays (FPGA)
- 6. Reconfigurable computing: 01 Can be used by implementing all of the application functionalities in hardware. The main advantage in this, is that the hardware can be easily replaced by downloading a configuration file on the chip, rather than having the circuit physically replaced.
- 7. We can thus conclude that reconfigurable computing is a trade off between general purpose computing and application specific computing, because it tries to achieve balance among performance, cost, power, flexibility, and design effort.
- 8. Is a semiconductor device containing programmable logic components, programmable interconnects and I/O Blocks. Field programmable gate arrays:
- 9. Field programmable gate arrays (FPGA), Is the latest reconfigurable computing technology.
- 10. FPGAs are programmed using Hardware Description Language (HDL), such as VERILOG HDL and VHDL.
- 11. FPGAs Applications Prototype Aerospace and defence Share Audio Processing Refine Wireless communication Get feedback Automotive industry 01 02 03 04
- 12. Arduino Microcontrollers are not FPGAs The main difference is that Arduino executes operations in a sequential fashion, whereas FPGAs are parallel computing devices.
- 13. General-purpose graphics processing units (GPGPU).
- 14. Quick review about:- ● General purpose computing ● Graphical processor unit (GPU)
- 15. What is General-purpose graphics processing units (GPGPU) ? Is a graphics processing unit (GPU) that is programmed for purposes beyond graphics processing. GPU + General purpose computing
- 16. Benefit of using GPGPU. GPUs can run certain algorithms anywhere from 10 to 100 or more times faster than CPUs.
- 17. Uses of GPGPU ● Scientific Computation ● generation of cypto currencies such as Bitcoin. ● Machine learning programs
- 19. An application-specific integrated circuit (ASIC /ˈeɪsɪk/) is an integrated circuit (IC) chip customized for a particular use, rather than intended for general- purpose use.
- 20. For example a chip designed to run in a digital voice recorder or a high-efficiency bitcoin miner is an ASIC. Application- specific standard product (ASSP) chips are intermediate between ASICs and industry standard integrated circuits like the 7400 series or the 4000 series. ASIC chips are typically fabricated using metal-oxide-semiconductor (MOS) technology, as MOS integrated circuit chips.
- 21. Early ASICs used gate array technology. By 1967, Ferranti and Interdesign were manufacturing early bipolar gate arrays. In 1967, Fairchild Semiconductor introduced the Micromatrix family of bipolar diode–transistor logic (DTL) and transistor–transistor logic (TTL) arrays. History
- 22. Gate array design is a manufacturing method in which diffused layers, each consisting of transistors and other active devices Gate-array
- 23. By contrast, full-custom ASIC design defines all the photolithographic layers of the device. Full-custom design is used for both ASIC design and for standard product design. Full-custom design
- 25. What does Vector Processor mean? A vector processor is a central processing unit that can work on an entire vector in one instruction. The instruction to the processor is in the form of one complete vector instead of its element. Vector processors are used because they reduce the draw and interpret bandwidth owing to the fact that fewer instructions must be fetched. A vector processor is also known as an array processor.
- 27. Advantages of Vector Processor ● Vector processor uses vector instructions by which code density of the instructions can be improved. ● The sequential arrangement of data helps to handle the data by the hardware in a better way. ● It offers a reduction in instruction bandwidth

Editor's Notes
- A general-purpose computer is one that, given the appropriate application and required time, should be able to perform most common computing tasks.
- such as performing computations typically conducted by a Central Processing Unit (CPU).
- Essentially all modern GPUs are GPGPU. . While GPUs were originally designed primarily for the purpose of rendering images, GPGPUs can now be programmed to direct that processing power toward addressing scientific computing needs as well. GPUs can process far more pictures and graphical data per second than a traditional CPU. Migrating data into graphical form and then using the GPU to scan and analyze it can create a large speedup.
