Tool chain used for build

The following tools have been used:

Compiler:  IAR ICC78400
Assembler: IAR A78400
Librarian: IAR XLIB
Workbench: IAR EW231   V2.31b

New features

Version 3.06d

1. Separate interrupt stack supported

Interrupts use a separate interrupt stack, so that interrupts do not use the task stacks. This reduces the required stack for every task.

Version 3.06

1. Upgrade from Version 2.2

embOS for 78K4 using IAR compiler was upgraded to version 3.06 with all features of actual embOS version 3.06 including embOSView

Improvements

Version 3.06

1. Context switching time

Context switching time has been measured as follows: 142us

2. Interrupt latency

Interrupt latency has been measured as follows: 56us
Measurements were taken with a target running in LARGE memory model with 8bit external memory running at 16MHz

Program corrections

Version 3.06d

1. Problem with Far code fixed.

Version 3.06

None.

Known problems / limitations

Version 3.06d

1. Register bank usage

Initial register bank is fixed to bank 0 for embOS. Register bank 1 is also used by embOS for interrupt stack switching.

Version 3.06

1. Actual Version 3.06 is available for the LARGE memory model only.
