Revised to V.2.01 Release 00 |
We have revised the real-time OS HI7000/4 to from V.2.00 to V.2.01 Release 00.
(This is used for the SuperH RISC engine family, supporting the MCUs using any of the SH-1, SH-2, SH2-DSP, SH-2A, and SH2A-FPU cores.)
- The Previous Versions of the Product to Be Revised
HI7000/4 V.2.00 Release 00, Release 01, and Release 02
- Descriptions of Revision
| 2.1 |
|
Functions Introduced and Improved
| (1) |
|
Improvements of variable-length memory pools made
Gaining and relinquishing memory blocks are performed very. rapidly. Also attribute value VTA_UNFRAGMENT has been introduced to reduce fragmentation of vacant areas. |
| (2) |
|
The initial values of the DSR registers in the DSP changed
The initial values of the DSR registers, which are used for the tasks with attribute value TA_COP0 and for the task exception- handling routine, have been changed from indefinite to 0s. |
| (3) |
|
The initial value of the SR register for the task exception- handling routine changed
The initial value of the SR register used for the task exception- handling routine has been changed from the same value as in the task before initiation to 0. |
| (4) |
|
Handling of vector numbers 16--24 and 26--31 improved
A handler can be defined for handling these vector numbers. |
| (5) |
|
The CFG_IBNR-ADR edit box introduced which assigns the address of the IBNR register
The CFG_IBNR_ADR edit box has been introduced on the configurator's. "Interrupt/CPU Exception Handler" page. This is used for assigning the address of the IBNR register.
The reason of the use of CFG_IBNR_ADR is that, in the previous version, the kernel accesses the IBNR register provided that a fixed address of H'fffe080e is assigned to the IBNR register, so the register bank cannot be used in the MCUs where different addresses are assigned to their IBNR registers. |
| (6) |
|
Restrictions on aligning the structure elements raised
The restrictions imposed on the pack option and the #pragma pack directive at compilation have been raised. |
|
| 2.2 |
|
Problems Fixed
The problems described in Sections 2.2.1 and 2.2.2 below have been fixed.
