The performance study was focused on comparable performance values under various circumstances.

5.9.1Java

This section gives information about the Java command execution throughput (“jPS”= Java statements per second). The scope of this measurement is only the statement execution time, not the execution delay (Java command on AT interface Î Java instruction execution

Îreaction on GPIO).

Figure 11: Test case for measuring Java command execution throughput

The following Java instruction was used for calculation of the typical jPS: value = ( 2 x number of calculation statements ) /

( ( 1 / frequencyB ) - ( 1 / frequencyA ) );

Measurement and calculation were done using:

•duration of each loop = 600 s

•number of calculation statements = 50 “result=(CONSTANT_VALUE/variable_value);”-

Instructions

(executed twice per pin cycle)

•frequencyA as measured with a universal counter

•frequencyB as measured with a universal counter

The reference loop has the same structure as the measurement loop except that the measurement sequence is moved.

Since only a small amount of Java code is executed in this test, it is easily optimized by the CLDC’s HI just-in-time compiler. More complex applications might not reach that execution speed.
