Tool chain used for build

The following tools have been used:

Fujitsu Softune Workbench V60L03

Compiler:  Fujitsu FCC911s    V60L03
Assembler: Fujitsu FASM911s   V60L03
Librarian: Fujitsu FLIBs      V60L01

Performance

1. Task switch time
   Release Library: 20.5 us = 984 CPU clock cycles
2. Interrupt latency of fast interrupts
   Zero
3. Interrupt latency of low priority interrupts
   Release Library: 9.25 us = 444 CPU clock cycles

Absolute timings are measured on an MB91F362 running at 48 MHz CPU clock

New features

Version 3.22a

1. Zero Latency, Fast interrupts
   Since version 3.22a, embOS for FR series supports zero latency for interrupts running with high priority.
2. OS_PutMailFront() / OS_PutMailFront1
   New mailbox functions to enable LIFO behavior of mailboxes.
3. OS_PutMailFrontCond() / OS_PutMailFrontCond1()
   New conditional mailbox functions to enable LIFO behavior of mailboxes.

Version 3.20

1. OS_Suspend() / OS_Resume() implemented
   New functions to suspend and resume tasks unconditionally.
2. Fixed size memory blocks inplemeted
   New functions to allocate fixed size memory blocks from embOS.
