Embedded Systems Classroom Training and Certification Classes

List file tells the opcodes, addresses and errors detected by the assembler. It can be used by programmer to find the syntax errors and fix them.

A program is always executed byte by byte.

The 2nd bit of the flag register is set when output flows to the sign bit. This flag is also called as the overflow flag.

Port0 and port2 together form the 16 bit address for external memory.

Infinite Loops are those program constructs where in there is no break statement so as to get out of the loop, it just keeps looping over the statements within the block defined.

• PC being overheated.
• Dust having being accumulated all around.
• CPU fans not working properly
• Faulty power connections.
• Faulty circuit board from where the power is being drawn.
• Support Drivers not having being installed.

The system can be debugged by thoroughly cleaning it and maintaining it in a dust-free environment. Environment that is cool enough and facilitates for easy passage of air should be ideal enough. Also, by locating the appropriate support drivers for the system in consideration and having them installed, the system can be debugged.

Java can be used on different platforms without any hassles and is a secure language. Java has various excellent features such as exception handling, simple syntax and automatic garbage collection which makes it ideal for use in embedded systems.

• Damage of memory devices due to transient current and static discharges.
• Malfunctioning of address lines due to a short in the circuit
• Malfunctioning of Data lines.
• Some memory locations being inaccessible in storage due to garbage or errors.
• Improper insertion of Memory devices into the memory slots
• Faulty control signals.

Single, Multiple, Multi-level and Hybrid.
