Chapter 4 Proper Firmware Development

Vocabulary flashcards based on Chapter 4 of firmware development, covering key concepts in assembly language and embedded systems.

State Machine

A computational model that consists of a set of states and transitions based on input, used for behavioral modeling.

Initialization

The process of preparing a system or component to become operational, typically involving the setup of parameters and configuration.

Interrupt Service Routine (ISR)

A special function in programming that gets executed in response to an interrupt, allowing for asynchronous event handling.

Fall-through Approach

A design technique in state machines where each state is executed sequentially unless a transition alters the flow.

AGS (Auto Grading Software)

Software designed to automate the evaluation of code submissions, ensuring adherence to the specified format and functionality.

Reset Vector

A specific address in memory where the program starts executing when the system is powered on or reset.

Subroutine

A block of code designed to be reused, performing a specific task and allowing the main code to remain clean and organized.

Delays in Firmware

Periods during which the system does not perform any operations, often used to synchronize activities or manage timing in embedded systems.

Transition Condition

Criteria that dictate the movement from one state to another within a state machine, governed by specific flags or inputs.

NIBBLE

A small grouping of code or a unit of work in programming, often used in educational contexts to facilitate learning of specific concepts.

Testing and Debugging

The process of running a program to identify and resolve errors or bugs, ensuring proper functionality before final deployment.

Switch Block

A control structure used to manually select and execute specific states or subroutines for testing and debugging purposes.

Microcontroller (µC)

A compact integrated circuit designed to govern a specific operation in an embedded system.

Code Example

A specific piece of code provided as a reference or illustration to demonstrate proper coding practices or techniques.

Table in Assembly Language

A structured format for organizing related data in memory, often used in conjunction with state machines for efficient access.
