  • Magnetic Recording and Readout Memory
    SNS college of Technology Coimbatore-641 035 MAGNETIC RECORDING AND READOUT MEMORY Nowadays, large number of information are stored in (or) retrieved from the storage devices, by using devices is magnetic recording heads and they function according to the principle of magnetic induction. Generally Ferro or Ferrimagnetic materials are used in the storage devices because in this type of materials only the magnetic interaction between only two dipoles align themselves parallel to each other. Due to this parallel alignment even if we apply small amount of magnetic field, a large value of magnetization is produced. By using this property information are stored in storage devices. In the storage devices, the recording of digital data (0‟s and 1‟s) depends upon the direction of magnetization in the medium. Magnetic parameters for Recording 1. When current is passed through a coil, a magnetic field is induced. This principle called “Electromagnetic Induction” is used in storage devices. 2. The case with which the material can be magnetized is another parameter. 3. We know the soft magnetic materials are the materials which can easily be magnetized and demagnetized. Hence a data can be stored and erased easily. Such magnetic materials are used in temporary storage devices. 4. Similarly, we know hard magnetic materials cannot be easily magnetized and demagnetized. So such magnetic materials are used in permanent storage devices. 5. In soft magnetic materials, the electrical resistance varies with respect to the magnetization and this effect is called magneto-resistance. This parameter is used in specific thin film systems. 19PYB102 & PHYSICS OF MATERIALS AND PHOTONICS D.SENGOTTAIYAN /AP/PHYSICS Page 1 SNS college of Technology Coimbatore-641 035 The magnetic medium is made of magnetic materials (Ferro or Ferric oxide) deposited on this plastic.

  • Investigation of Fast Initialization of Spacecraft Bubble Memory Systems Karen T, Looney, Charles D, Nichols., and Paul J, Hayes
    N 8 4 - 2 7 0 7 7 NASA Technical Memorandum 85832 INVESTIGATION OF FAST INITIALIZATION OF SPACECRAFT BUBBLE MEMORY SYSTEMS KAREN T, LOONEY, CHARLES D, NICHOLS., AND PAUL J, HAYES JUNE 1984 NASA National Aeronautics and Space Administration Langley Research Center Hampton, Virginia 23665 SUMMARY Bubble domain technology offers significant improvement in reliability and functionality for spacecraft onboard memory applications. In considering potential memory system organizations, minimization of power in high capacity bubble memory systems necessitates the activation of only the desired portions of the memory. In power strobing arbitrary memory segments, a capability of fast turn-on is required. Bubble device architectures, which provide redundant loop coding in the bubble device, limit the initialization speed. Alternate initialization techniques have been investigated to overcome this design limitation. An initialization technique using a small amount of external storage has been demonstrated, using software written in 8085 assembly language and PL/M. ' This technique provides several orders of magnitude improvement over the normal initialization time. INTRODUCTION Bubble memory systems are quickly becoming a preferred storage medium in environments where a non-volatile storage medium is required. The utilization of a bubble storage system offers the benefits of increased reliability, reduced maintainance, and permanent data integrity. The implementaton of large bubble memory systems in spacecraft applications requires that the memory modules be power strobed for the conservation of the available energy resources. Each time a module is turned on for use it must be initialized to code the redundant loop information of the selected bubble devices into the bubble controller. Present structures of bubble systems dictate that a faster initialization procedure is needed in order to capitalize on the advantages offered by a bubble memory system.

The tube, tested in 1947, was the first high-speed, entirely electronic memory. It used a cathode ray tube (similar to an analog TV picture tube) to store bits as dots on the screen’s surface. Each dot lasted a fraction of a second before fading so the information was constantly refreshed. Information was read by a metal pickup plate that would detect a change in electrical charge. Maurice Wilkes with EDSAC Maurice Wilkes and his team at the University of Cambrid construct the Electronic Delay Storage Automatic Calcula (EDSAC). EDSAC, a stored program computer, used me delay line memory. Wilkes had attended the University of Pennsylvania's Moore School of Engineering summer sessions about the ENIAC in 1946 and shortly thereafter Magnetic drum memory began work on the EDSAC. 1950 MIT - Magnetic core memory ERA founders with various magnetic drum memories Eager to enhance America’s codebreaking capabilities, the US Navy contracts with Engineering Research Associates (ERA) for a stored program computer. The result was Atlas, completed in 1950. Atlas used magnetic drum memory, which stored information on the outside of a rotating cylinder coated with ferromagnetic material and circled by read/write heads in Jay Forrester holding early core memory plane fixed positions.

  • System-On-A-Chip
    System-on-a-chip From Wikipedia, the free encyclopedia Jump to: navigation, search System-on-a-chip or system on chip (SoC or SOC) is an idea of integrating all components of a computer or other electronic system into a single integrated circuit (chip). It may contain digital, analog, mixed-signal, and often radio-frequency functions – all on one chip. A typical application is in the area of embedded systems. If it is not feasible to construct an SoC for a particular application, an alternative is a system in package (SiP) comprising a number of chips in a single package. SoC is believed to be more cost effective since it increases the yield of the fabrication and because its packaging is simpler.

These blocks are connected by either a proprietary or industry-standard bus such as the AMBA bus from ARM. DMA controllers route data directly between external interfaces and memory, by-passing the processor core and thereby increasing the data throughput of the SoC.
