Cross-Platform Development Process (Part 2) – Module 3

Fill-in-the-blank flashcards covering key terms and concepts from the Cross-Platform Development Process (Part 2) lecture: compilers, linkers, ELF structure, memory mapping, testing on target, and system production.

A is a program that translates source code into machine language (0s and 1s).

Compiler

A translates high-level code like C or C++ into machine code for another device.

Cross Compiler

A translates low-level assembly code on your PC for a different target device.

Cross Assembler

Cross-compiling is useful because the target device is often too _ to build the software itself.

weak / resource-limited

Building one program that runs on phones, tablets, and other devices demonstrates _ development.

cross-platform (portable) development

A puts together all separate object files into one final working program.

Linker

The linker’s job of connecting symbols across files is called .

Symbol Resolution

The linker’s task of adjusting addresses for real memory is called .

Symbol Relocation

A _ Object File is partially compiled and still needs linking.

Relocatable

A _ File is fully linked and ready to run on the target device.

Executable File

A _ Object File holds code that can be shared by multiple programs.

Shared Object File

Using one big file that contains everything a program needs is called .

Static Linking (Stand-alone)

Loading libraries at run-time instead of embedding them is known as .

Dynamic Linking

Before the OS can run a program, a (interpreter) loads it into RAM.

program loader

ELF stands for and _.

Executable and Linking Format

In an ELF file the first part that identifies the file is the .

ELF Header

The _ Header Table tells the OS how to load segments into memory at run-time.

Program

The _ Header Table lists all sections when linking the program.

Section

The _ view of an ELF file is used during compile/link time and sees the file as sections.

Linking View

The _ view of an ELF file is used at run-time and sees the file as segments.

Execution View

Mapping parts of a program into specific areas of RAM is called .

Memory Mapping

Sending the built program from the host to the embedded board is called the to the target.

transferring the executable (file/object)

Running and testing the complete system on the real device is known as on target.

Integrated Testing

Bugs where two operations occur simultaneously causing errors are called .

Race Conditions

In production, developers often switch to cheaper or smaller _ / memory to save cost.

microprocessors

A successful embedded project needs Hardware Engineers, Software Engineers, and _ Engineers.

Systems

Poorly written device _ can cause the entire system to fail during testing.

drivers

A portability issue exists when software runs on one device but _ on another.

won’t work / fails

Ensuring actions happen at the correct moment addresses _ issues.

Timing

The statement “The target device is the computer where the program is written” is _.

FALSE
