Introduction
A DMA Controller is a device, which takes over the system bus to directly transfer information from one part of the system to another. This is necessary because often blocks of data have to be moved very rapidly, sometimes at speeds even faster than is practical, if each byte were to move through the CPU. For example, displaying pictures on a video screen requires a complete scan (one frame) of the screen 30 times a second or a half scan (one field) every 60 seconds. Suppose we wish to display a black an ....etc

ABSTRACT
Many system-on-chip (SoC) integrated circuits contain embedded cores with different scan frequencies. To better meet the test requirements for such heterogeneous SoCs, leading tester companies have recently introduced port-scalable testers, and Many IP core design software like Xilinx, Leonardo Spectrum, and Modelsim etc which can used to design ip core like DMA ,Interrupt Controller etc .These Ip core can be Power aware an Implement on soc by choosing different design tech ....etc

Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged .these two states are taken to represent the two values of a bit, conventionally called 0 and 1. Since capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically.The advantage of DRAM is its structural simplicity. only one transistor and a capacitor are required per bit, compared to six transis ....etc

Digital frequency meter using DMA Terminal Count stop method
Abstract-
This paper presents a new wide-range speed
measurement method, using the direct memory access
(DMA) terminal count register(TCR). The DMA
method is based on both pulse counting in the constant
sampling time at terminal count stop pin of a DMA
controller. The hardware configuration and algorithms
for a microcontroller implementation are also
presented. The proposed method is suitable in systems
using microcontrollers with DMA controller and
timers. Li ....etc
