SPMarkJava JSR 184 2D Game Test

• Designed to replicate workload of simple game with bitmap graphics: Driving game with bird’s eye view
  • MIDP 2.0 required to run test
  • Test measures performance on CLDC 1.0 devices
  • javax.microedition.lcdui.game package classes used heavily including bitmap rendering and collision detection
  • Workload generated by adding independently scrolling bitmap layers with transparency o
  • ace track rendered as single, large, fully opaque TiledLayer object
  • Benchmark code operates as a fully playable, but limited game (Game available only in Advanced and Professional Editions)
  • Performance measurement reported as Frames per second

SPMarkJava JSR 184 Feature Tests

• 3D Fill Rate test
  • Measures the 3D fill rate of the target device
  • Draws two 256*256 textures to a single triangle polygon
  • Uses two texture units if available
  • Rotation used as a visual effect
  • Performance measurement reported as thousand texels per second (Ktexels/s)
• 3D Polygon Throughput test
  • Measures the amount of polygons drawn on the screen
  • Draws a set of 9 torus knots with 10 000 triangles on the screen
  • Polygons are lit
  • Performance measurement reported as thousand vertices processed per second
• Video Processing
  • Measures video playback
  • Uses H.263 Codec and JSR 135 API
  • 176 x 144 resolution
  • 15 FPS frame rate
  • 40kBps bit rate
  • Measurement reported as “Pass/fail”
  • This test is available only in the Professional Edition
• Image Processing
  • Portions of an image are encoded and decoded on screen
  • PNG image format (the format widely used in internal image storing in handheld devices)
  • Each test operation result is displayed
  • Geometric mean of both operations used to produce test results
  • The result is given as a geometric mean of encoding and decoding test results. The individual test results in kPixels processed per second are also available
• JVM-Test
  • Theoretical test, consisting of series of subtests
  • Subtests measure specific JVM operations
  • Subtests vary from simple arithmetic operations to complicated but critical operations such as object creation
  • Different data type variations tested:
    • 32bit
    • 64bit
  • Subtests include:
    • Integer addition and subtraction in various data types
    • Integer multiplication and division in various data types
    • Conditional code test (if-else-statement)
    • Simple object creation test
    • java.lang.System.arraycopy(…) test – results in MB/s
    • Static method call
    • Array read access
    • Floating point addition/multiplication tests (these tests require CLDC 1.1)
    • Sine, cosine, tangent and square root calculations (these tests require CLDC 1.1)
  • Performance measurement reported as operations per second
  • Individual test results displayed
  • Overall JVM-Test score is a geometric mean of subtest scores
• Battery Test
  • User selected tests run in looped sequence until battery is fully drained or the OS shuts down the Java application due to low battery.
  • Measurement reported as the Time to drain battery in seconds
  • Results not factored into overall SPMarkJava JSR 184 score
  • This test is available only in the Professional Edition
