Error-removing device and method for optical storage apparatus

Abstract

The invention is a debugger for optical storage device, comprising a debug control unit arranged on the optical storage device, an information converting circuit connected with the optical storage device and a computer device connected with the information converting circuit, where the debug control unit is used to convert the operating signals generated by the optical storage device into information codes by the predefined rules and control to transmit the information codes to the information converting circuit; the information converting circuit is used to convert the information codes into interfaced signal to the computer device; the computer device is used to receive and resolve the interfaced signal. And the debugger and the debugging method convert the complicated debug information into functional codes and information codes with small data quantity, and the debug information can be transmitted to the computer device on the condition of not causing too much system load.

Description

【Technical field】 [0001] The invention relates to a device and method for debugging an optical storage device, in particular to a device and a method for debugging an optical storage device under high-speed operation. 【Background technique】 [0002] When developing optical storage devices, in order to shorten the product development time, it is necessary to use debugging tools for debugging. The general debugging tool is to provide developers with real-time (Real Time) understanding and control of the internal operation of the optical storage device. If it is connected to a logic analyzer through an RS-232 serial port or a parallel port, it can output the operating signals of the optical storage device in real time, thereby providing a basis for troubleshooting. Alternatively, an In-Circuit Emulator (ICE) is built into the circuit between the microprocessor and the bus to provide developers with monitoring and controlling the input and output of all signals of the microproc...

Problems solved by technology

However, the above debugging method can only be used when the system is under light load or low access rate

And although the ICE emulator method can be used to debug errors by setting breakpoints or single-step execution, it can only be used during system activation or process tracking that has nothing to do with timing

In addition, ICE is a relatively expensive component, making the development cost relatively high

In the high-speed optical storage device, the system load is very high, and the system operation signal is transmitted without affecting the operation of the device. The traditional debugging method may cause system abnormality and instability.

There is also a way to use parallel ports to output debugging information, but this method requires more input and output pins, and is only suitable for device systems with independent components, not for multi-chip packages (Multi-Chip) equipment system
