“…FPGAs have been used for prototype design in a range of engineering application [1,[14][15][16][17][18][19]; however, till date to the authors' knowledge, the design of a complete application-specific controller for different flash memory card access with detailed description of the modules and their operation is limited. Table 1 depicts some of the earlier work in this domain.…”

“…The flash-based memory storage device, introduced by Toshiba in 1984, is basically a non-volatile electronic memory and used whenever a shock resistance is the key requirement of any application [1]. The Secured Digital High Capacity (SDHC) card, for example, is a flashbased memory storage device and is mainly designed to meet certain requirements such as security, capacity, performance, and environmental issues inherent in newly emerging audio and video consumer electronic devices.…”

“…The SD card includes an on-card intelligent controller to manage the interface protocol, security algorithms, data storage and retrieval, error handling and corresponding error correction code (ECC) algorithms, defect handling and diagnostics, power management, and clock control [1]. However, to interface the SDHC card (slave unit) with master unit (e.g., computer, host, or any applicationspecific device), we need a system which can talk with the on-card controller of the SDHC card for smooth execution of single/multiblock data read/write.…”

Real-time multimedia data access plays an important role in electronic systems; as time goes by, with decrease in data processing speed and increase in communication time, storage time, and retrieval time, the overall response time increases for real-time applications. Therefore, in this paper, a novel real-time, fast, low-cost, system-on-chip (SoC) controller has been proposed and implemented where large volume of data can be efficiently stored and retrieved from flash memory cards. It is being implemented only using hardware description language (HDL) on a field programmable gate array (FPGA) chip without using any other on-board or external hardware resources or high-level languages. The entire controller architecture, in a single chip, contains five different modules and is designed using finite state machine (FSM)-based approach. The modules are card initialization module (CINM), idle module (IM), card read module (CRM), card write module (CWM), and decision module (DM). The architecture is completely synthesized for Spartan 3E xc3s500e-4-fg320 FPGA with only 5% of the total logic utilization. The experimental results tested for microSD, SD, and SDHC cards of different size, and these show that the architecture uses less hardware and clock cycles for card initialization and single/multiblock read/write procedure.

Graphics image files can be stored in different file formats. One of the most general form is bitmap image format. Bitmap file format is an uncompressed form of image consisting of matrix of pixel constructing the image. BMP (24bit) represents each pixel in set of 24 bits comprising of RGB(Red, Green, Blue). Where BMP(32bit) represents one additional byte of alpha for transparency/opaque. Researcher identified redundancy of colors and made model to compress BMP(24bit) file. A model is developed to list all unique color of the image and store only index of these unique color instead of the whole 3 RGB color. The compression performance is based on number of unique colors and width-height of the image. In this paper researcher has made an effort to extract such bit patterns representing the pixel and then using such different bit patterns determines the total number of colors represented in image. Once the number of color is found it is possible to compress the file by grouping similar colors with exact pixel positions. Paper is prepared based on the research to analyze the image file and then compressing it. The model demonstrated here for 24bit file and at last concluded with tradeoff, improvements and limitation.
