85 Diverse RTL cosmetic updates. olivier.girard 4908d 08h /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 4913d 09h /openmsp430/trunk/core/rtl/
79 Update the GPIO peripheral to fix a potential synchronization issue. olivier.girard 4974d 09h /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 5061d 09h /openmsp430/trunk/core/rtl/
72 Expand configurability options of the program and data memory sizes. olivier.girard 5088d 10h /openmsp430/trunk/core/rtl/
67 Added 16x16 Hardware Multiplier. olivier.girard 5235d 17h /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.		 olivier.girard 5235d 21h /openmsp430/trunk/core/rtl/
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 5267d 08h /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 5269d 06h /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.		 olivier.girard 5274d 11h /openmsp430/trunk/core/rtl/
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 5303d 10h /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 5303d 11h /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 5424d 12h /openmsp430/trunk/core/rtl/
17 Updated header with SVN info olivier.girard 5450d 08h /openmsp430/trunk/core/rtl/
2 Upload complete openMSP430 project to the SVN repository olivier.girard 5485d 08h /openmsp430/trunk/core/rtl/
