Design and Implementation of Synthesizable VHDL Model for General PCMCIA I/O Cards Controller

Abstract

AbstractThe portable and nomadic computer market has driven the development ofPCMCIA Cards to address the expansion needs for the user. These cards provide avast variety of hardware devices which are rugged, credit-card sized, lightweight,and power efficient. These cards are easy to use, especially for the non-technicaluser. Since the sockets are accessible from the outside of the system, the systemdoes not have to be powered-off, opened, and rebooted to add or remove a device.This dynamic insertion and removal feature inherently makes these devices powermanageable and also allows devices to easily be shared among different computers.This paper is concerned with type II PC cards, which mean I/O cards,therefore a design and implementation of synthesizable VHDL model for controlsystem (Controller) of the PCMCIA I/O cards is presented.The implementation of the control system (controller) has been done by using veryhigh speed hardware descriptive language (VHDL) and its implementation on fieldprogramming gate array (FPGA) type Xilinx Spartan 2 (XC2S30-6 Pq208) byusing synthesis and implement tools of ISE6.3 program.The used of FPGA technology is optimal for this paper because it offers highreliability and flexibility in modifying and even developing the required designwith a reduction in the required number of hardware components, also the nonrecurring engineering cost.The timing behavior of the controller is be tested and verified to ensurethat it meets the performance requirements by using simulation tools of Active-HDL program AND Daley report of ISE program, therefore examples ofsimulation results of read/write transfers for both an attribute memory and I/Odevices are presented in this paper.
