Parallel Port Revival

Hebbeker, Thomas · Zenodo (CERN European Organization for Nuclear Research) · 2024

The classical parallel port interface used to provide an easy way to write or read digital in- and outputs (IOs) and thus to control peripheral electronic devices connected to a personal computer. Conventional modern computers do no longer provide such a simple hardware access. Here several alternatives are presented, allowing to access parallel port devices via USB, WiFi, Ethernet or Bluetooth.

Parallel Printer Port for Phase Measurement

R. Padma Suvarna, Dr.M. Usha, P. Kalyani et al. · International Journal of Advanced Computer Science and Applications · 2010

This white paper talks about the measurement of phase angle using Phase Locked Loop and printer port.. The phase detector compares the phase of a periodic input signal against the phase of the output of voltage controlled oscillator and generates an average output voltage Vout which is linearly proportional to the phase difference, ?ø between its two inputs. This output voltage is measured using the parallel Printer port of a PC.

Compact ADC DAC Interface for Parallel Port

D. N. Kyatanavar, Minal Patil, G G Tengashe et al. · IETE Journal of Education · 2006

In the modern world of electronics and process control instrumentation, computers are used for automation and to achieve high speed and accuracy. Hence it is required to have a simple, efficient and reliable interface, which can establish the connection between analog and digital world. In this paper, we have discussed the design and fabrication of such an interface card. This card can be plugged into readily available parallel port of PC. The samples of analog signal can be obtained through this card and processed samples can be converted back into analog form using the DAC available on the card. This design makes use of readily available low cost ICs. The signal processing software can be developed using any of the commercially available high level software languages like C++, VB and VC etc. For the specialized applications, software like MATLAB can also be used along with this card. This card can also be used for instrumentation and control applications like implementation of PID controller etc.

Jaramillo Cantu, Hector · KTH Publication Database DiVA (KTH Royal Institute of Technology) · 2006

The present work will explain a method to achieve a remote controlled (via IR LED) alphanumeric Liquid Crystal Display. In modern times, the remote access of different devices has become quite popular, therefore, the aim of this project is to provide a useful tool that will integrate common and easy to access devices. The system includes a C language based user interface, an assembly language code for the AT89C51ED2 microcontroller instructions and some digital electronic circuits needed for the driving and control of both the LCD and the infrared communication, as well as the PC with a parallel port. The interaction of all the devices provides a whole system that can be helpful in different applications, or it can be separated into each one of its different stages to take the best advantage as possible.

MIDI Output Interface to a Parallel Printer Port

D. M. Gualtieri · Computer Music Journal · 1986

MIDI (the Musical Instrument Digital Interface) has become a standard feature on electronic keyboard instruments. MIDI is a serial, current-loop, data transmission network that is a hardware and software standard maintained by the International MIDI Association (11857 Hartsook St., North Hollywood, California 91607 USA; telephone (818) 505-8964). MIDI has been designed to allow detailed control of keyboard instruments by other keyboard instruments or computers. The MIDI standard specifies coding for note-on, note-off, note velocity, key pressure, and other parameters related to musical keyboard playing. MIDI has 16 timedivision multiplexed channels, so that sixteen instruments can be individually accessed from one MIDI network. The 31.25 Kbaud signalling rate allows real-time control of these instruments. MIDI is a bidirectional network. Performance information can be generated by a keyboard instrument to be transcribed in computer memory or in a data file, but the most common application is the external control of an instrument by a sequencer or computer. Scores can be edited on a computer, a MIDI data list can be generated, and a composition can be heard in real time on a group of selected instruments.

Parallel simulation of AGVs in container port operations

Rong Ye, Voon-Yee Vee, Wen-Jing Hsu et al. · 2000

We describe parallel simulations of an Automated Guided Vehicle (AGV) system for the container handling at a port. The AGV system is modelled with a time-driven approach and executed on efficient simulation engines implemented by using Cilk, a multi-threaded parallel programming language developed at MIT. The speedup remits of the AGV simulation over sequential versions are documented. We also present congestion control schemes of our AGV routing system.

Performance Analysis of Serial and Parallel Six-Port Modulators

Bin Luo, M.Y.W. Chia · IEEE Transactions on Microwave Theory and Techniques · 2008

We have derived the transfer functions for two types of six-port quadrature phase-shift keying (QPSK) modulators and investigated their performances in terms of carrier leakage, Gray mapping, and conversion efficiencies. Our result shows that the carrier leakage is minimized when Gamma <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ON</sub> = -Gamma <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OFF</sub> . In addition, our analysis reveals here that only the parallel six-port QPSK modulator demonstrates a Gray mapping feature. Our analysis further proves that the serial and parallel modulator give a maximum conversion efficiency of 100% and 50%, respectively, but the efficiency of the serial modulator deteriorates faster than the parallel modulator when the terminations are not ideal. We have also shown that the serial modulator requires tighter design tolerances due to its cascaded topology. Our theoretical and measured results show good agreements with the six-port modulators developed for 4.2 GHz.

GPU Port of A Parallel Incompressible Navier-Stokes Solver

Based On Openacc · 2014

OpenACC is a directive-based programing standard aim to provide a highly portable programming model for massively-parallel accelerators, such as General-purpose Com-puting on Graphics Processing Units (GPGPU), Accelerated Processing Unit (APU) and Many Integrated Core Architecture (MIC). The heterogeneous nature of these accelera-tors stresses a demand for careful planning of data movement and novel approaches of parallel algorithms not commonly involved in scientific computation. By following a simi-lar concept of OpenMP, the directive-based approach of OpenACC hides many underlying implementation details, thus significantly reduces the programming complexity and in-creases code portability. However, many challenges remain, due to the relatively narrow interconnection bandwidth among GPUs and the very fine granularity of GPGPU archi-tecture. The first is particularly restrictive when cross-node data exchange is involved in a cluster environment. Furthermore, GPGPU’s fine-grained parallelism is in conflict with certain types of inherently serial algorithms, posing further restrictions on performance. In our study, an implicit multi-block incompressible Navier-Stokes solver is ported for GPGPU using OpenACC and MVAPICH2. A performance analysis is carried out based on the profiling of this solver running in a InfiniBand cluster with nVidia GPUs, which helps to identify the potentials of directive-based GPU programming and directions for further improvement. 1
