Problems solved by technology

Since some DSPs have programming ports that can directly control the EEPROM, and some do not directly control the programming port of the EEPROM, but rely on the on-chip EEPROM pre-stored program to read and write the off-chip EEPROM, so it is necessary to rely on 23, 25 pins It is very difficult to completely control the data reading and writing of the hard disk and the rewriting of the on-chip and off-chip EEPROM in the flat state

Embodiment Construction

[0011] Describe the present invention in detail below in conjunction with accompanying drawing, from figure 1 It can be seen that the technical principle of the present invention is that a simulated hard disk device for a computer is composed of a hard disk simulator for simulating and managing the working state of the hard disk and a hard disk magnetic head read-write controller controlled by the hard disk simulator, composed of a DSP chip, a RAM , EEPROM, and IDE40-type interfaces are connected to each other to form a hard disk simulator. It is connected to the motherboard ATA interface through a set of 40-pin IDE40-type interfaces consistent with the hard disk IDE interface specifications. The DSP chip is connected to the magnetic head read and write current controller, and the magnetic head read and write current The controller is connected to the interface between the hard disk head of the computer and the hard disk circuit board to form a parallel connection with the orig...

Abstract

The present invention discloses an analog hard disk device for computer, including hard disk simulator and hard disk magnetic head reading and writing controller, said hard disk simulator is formed from DSP chip, RAM, EEPROM and IDE 40 type interface, it can be parallel to original hard disk of computer for receiving instruction of ATA bus. The magnetic head reading and writing controller can be directly controlled between hard disk magnetic head and hard disk control circuit, and can be used for making reading and writing operation by means of on-off action of current, also can be used for monitoring writing signal of EEPROM on DSP chip by means of on-off action of main power supply.

Description

Technical field [0001] The invention relates to the technical field of computer hardware, in particular to an analog hard disk device for a computer. Background technique [0002] Today, computer technology has been widely used in various fields of people's life, work and study, and its importance is self-evident. Computers are composed of hardware systems and software systems. The hardware system is the foundation, and the hard disk is the most important part of the computer. Storage devices, including the operating system, for various software, programs, and data need to be stored on the hard disk, and the hard disk is mainly composed of interface circuits and control circuits, through the bus connected to the input and output devices and the central processing unit. The IDE interface bus technology is the commonly used read-write and control technology at present. Although the known read-write control of the IDE bus technology uses the level control of 23 and 25 pins, it ...
