Work Package Progress 1

• WP7d Hume Model Checking
• Gudmund Grov paper at ACM ASE PhD Symposium on
  model checking HW-Hume
• WP7e Hume Problem Solving Env

Work Package Progress 2

• WP7f Hami on Microcontroller
• Renesas M32 development kit acquired for HWU
  AbsInt
• Hami successfully ported to development kit
• now supports memory mapped I/O interrupts
• Hami rationalised/streamlined
• good basis for compilation

Work Package Progress 3

• WP8 Real Time Computer Vision Algorithms
• motion-tracker completed in C Hume in Aug/Sept
  2005 by Iain Wallace - Nuffield Undergraduate
  Research Scholarship student
• 3 Hume versions rec lists rec vectors box
  vectors
• all available to EmBounded partners
• identified Hume language interpreter wrinkles

Work Package Progress 4

• WP9 Basic Language Features
• WP7 Java from HW-Hume translation available
• e.g. full adder Roscoe railway from CSP
• WP 8 motion-tracker C Hume have equivalent
  behaviour

Current Activity

• finalise/document/distribute Hami on M32 - RP
• native code compilation for Intel - RP
• HW-Hume on Isabelle/HOL to prove HW-Hume to Java
  compiler - CL
• specification notation for Hume - GG
• explore TLA Isabelle/HOL for integrating model
  checking correctness - GG
