REAL-TIME systems
BSIT-1E McAfee
PLATFORM TECHNOLOGIES
DEFINITION
Real-time systems are computer systems
that are designed to respond to events or
commands within strict timing
constraints.
CHARACTERISTICS
• Timing Constraints
• Predictability
• Reliability
TIMING CONSTRAINTS
Real-time systems must meet specific
deadlines for processing and responding
to events.
PREDICTABILITY
The behavior of real-time systems needs
to be predictable, ensuring that tasks are
completed within their specified time
limits.
RELIABILITY
Real-time systems must be highly
reliable, as their failure to meet timing
constraints can result in serious
consequences.
types of real-time
Systems
These systems have strict and critical timing
requirements, where a missed deadline can lead
to catastrophic outcomes.
Hard Real-time System Soft Real-time System
These systems have timing requirements that are
important, but missing occasional deadlines may
not cause severe consequences.
REFERENCE MODEL
• Workload Model
• Resource Model
• Algorithms
AdvANTAGES
• Provide immediate and accurate responses to external events,
making them suitable for critical applications such as air traffic
control, medical equipment, and industrial automation.
• They can automate complex tasks that would otherwise be
impossible to perform manually, thus improving productivity
and efficiency.
AdvANTAGES
• Can reduce human error by automating tasks that require
precision, accuracy, and consistency.
• They can help to reduce costs by minimizing the need for
human intervention and reducing the risk of errors.
• Can be customized to meet specific requirements, making
them ideal for a wide range of applications.
disAdvANTAGES
• Can be complex and difficult to design, implement, and test,
requiring specialized skills and expertise.
• They can be expensive to develop, as they require specialized
hardware and software components.
• Are typically less flexible than other types of computer
systems, as they must adhere to strict timing requirements
and cannot be easily modified or adapted to changing
circumstances.
disAdvANTAGES
• They can be vulnerable to failures and malfunctions, which can
have serious consequences in critical applications.
• Require careful planning and management, as they must be
continually monitored and maintained to ensure they operate
correctly.
APPLICATION
• Aerospace & Defence
• Industrial Automation
• Health Care
• Transportation
CONCLUSION
• Real-time systems play a vital role
in critical applications where timing
and reliability are crucial. Their
usage spans across various
industries and domains.
