Why use Java instead of C or C++?

25% average savings per project

40% savings during coding phase

10-20% in production support

30% or more ongoing code maintenance

Reasons cited:

built-in memory management and simplified object orientation

IDC – “Java Technology Pays Positively”

Why use Java instead of C or C++?

“A typical C++ program had two to three times as many bugs per line of code…”

“C++ generated between 15% and 50% more defects per line”

“and took six times as long to debug”

“Java was between 30% and 200% more productive…”“Comparing Observed Bug and Productivity Rates for Java and C++”, Geoffrey Phipps, 2001

Why use Java instead of C or C++?

#1 Most Popular Language

6JamaicaVM

Why use Java instead of C or C++?

• Reduce development time

• Reduce the need to “re-implement code”

• Reduce QA time

• Reduce shipped bugs & defects

Increase Productivity

Increase Code Reuse

Increase Code Quality

Increase access to potential developers: #1 most popular language (July 2010 Tiobe Index)

Why Isn’t Java Used in Embedded & Realtime Applications?

Objections often cited by experienced embedded engineers:

“Java applications are too big”

“Interpreted Java applications are too slow”

“Java programs pause & delay unpredictably”

“Java memory management (garbage collection) is nondeterministic”

“Scoped Memory is too difficult to use”(Realtime Specification for Java)

“Lack of Java on embedded platforms”

Why Isn’t Java Used in Embedded & Realtime Applications?

All of those objectionsused to be true

BUT NOT ANYMORE!

9JamaicaVM

Embedded & Realtime Java

What if there was a solution for Java’s– application size?

– Pause & Delay unpredictably?

– nondeterminism?

– Interpreted performance?

– Scoped Memory complexity?

– Lack of availability for embedded platforms?

What if you could realize

Reduced development time?

Reduced QA time?

Reduced bugs & defects?

Increased code quality and reuse?

Increased access to qualified developers?

Increased number of releases per year?

The JamaicaVM Solution

Presenting , the Best Java Solution for Embedded & Realtime

Application Development

11JamaicaVM

The JamaicaVM Solution

Java Problems• Unpredictable pauses & delays

• Java nondeterminism

• Java application size

• Interpreted Java performance

• Java RTSJ Scoped Memory complexity problem?

• Lack of Java on Embedded Platforms?

JamaicaVM SolutionMultithreaded Hard Realtime Garbage

Collector (“RTGC”)

Worst Case Execution Time Analysis (“WCETA”) possible with RTGC

Smart Linker reduces executable size by up to 90%

Ahead-of-time (“AOT”) Compiler delivers “native” compiled code performance

No need for Scoped Memory

Support for most embedded OS’es and CPU’s

12JamaicaVM

The JamaicaVM Solution

Real Benefits

• Project deadlines are met: Gains in productivity help meet scheduling

• Developers learn new skills: Mastery of current technology helps attract and keep talent

• On time projects, low defect rates, and expert developers =

Satisified Management!
