Abstract
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. © 2016, The Author(s).
