91 Fixed bug when an IRQ arrives while CPU is halted through the serial debug interface.
This bug is CRITICAL for people using working with interrupts and the Serial Debug Interface.
olivier.girard 4850d 23h /openmsp430/trunk/core/rtl/
86 Update serial debug interface test patterns to make them work with all program memory configurations. olivier.girard 4873d 20h /openmsp430/trunk/core/rtl/
85 Diverse RTL cosmetic updates. olivier.girard 4873d 22h /openmsp430/trunk/core/rtl/
84 Update SRAM model in the core testbench to prevent the IEEE warning when running simulations.
Update watchdog to fix NMI synchronisation problem.
Add synchronizers for the PUC signal in the debug interface.
olivier.girard 4878d 23h /openmsp430/trunk/core/rtl/
79 Update the GPIO peripheral to fix a potential synchronization issue. olivier.girard 4940d 00h /openmsp430/trunk/core/rtl/
74 Update serial debug interface to support memories with a size which is not a power of 2.
Update the software tools accordingly.
olivier.girard 5026d 23h /openmsp430/trunk/core/rtl/
72 Expand configurability options of the program and data memory sizes. olivier.girard 5054d 00h /openmsp430/trunk/core/rtl/
67 Added 16x16 Hardware Multiplier. olivier.girard 5201d 07h /openmsp430/trunk/core/rtl/
66 The peripheral templates are now under BSD license.
Developers of new peripherals based on these templates won't have to disclose their code.

60 Cleanup of the PC (R0) generation logic.
Formal equivalence was shown between the new and old code with Synopsys' Formality (to make sure that nothing has been broken :-P ).
olivier.girard 5232d 22h /openmsp430/trunk/core/rtl/
57 Update design to exclude the range mode from the debug hardware breakpoint units. As this feature is not used by GDB, it has been disabled in order to improve the timings and save a bit of area/utilisation.
Note that if required, this feature can be re-enabled through the `HWBRK_RANGE define located in the "openMSP430_defines.v" file.
olivier.girard 5234d 20h /openmsp430/trunk/core/rtl/
53 Fixed the following combinatorial timing loop:
1- irq_detect (omsp_frontend)
2- decode (omsp_frontend)
3- dbg_swbrk (omsp_dbg)
4- halt_flag_set (omsp_dbg)
6- dbg_halt_cmd (omsp_dbg)
7- irq_detect (omsp_frontend)

Without this fix, problem could occur whenever an IRQ request arrives during a software breakpoint instruction fetch.

34 To avoid potential conflicts with other Verilog modules in bigger projects, the openMSP430 sub-modules have all been renamed with the "omsp_" prefix. olivier.girard 5269d 00h /openmsp430/trunk/core/rtl/
33 In order to avoid confusion, the following changes have been implemented to the Verilog code:
- renamed the "rom_*" ports and defines to "pmem_*" (program memory).
- renamed the "ram_*" ports and defines to "dmem_*" (data memory).

In addition, in order to prevent potential conflicts with the Verilog defines of other IPs, a Verilog undefine file has been created.
olivier.girard 5269d 01h /openmsp430/trunk/core/rtl/
23 Renamed the "openMSP430.inc" file to "openMSP430_defines.v" & added the "timescale.v" file.
In order to follow the same structure as other OpenCores projects, the timescale and the defines are now included from within the Verilog files (using the `include construct).
olivier.girard 5390d 03h /openmsp430/trunk/core/rtl/
17 Updated header with SVN info olivier.girard 5415d 22h /openmsp430/trunk/core/rtl/
2 Upload complete openMSP430 project to the SVN repository olivier.girard 5450d 22h /openmsp430/trunk/core/rtl/
