111 Re-organized the "openMSP430_defines.v" file.
Re-defined the CPU_ID register of the debug interface (in particular to support custom user versioning).
Added RTL configuration possibility to expand the peripheral address space from 512B (0x0000 to 0x0200) to up to 32kB (0x0000 to 0x8000).
As a consequence the per_addr bus width goes from 8 to 14 bits and the peripherals address decoders have been updated accordingly.		 olivier.girard 4739d 01h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
106 Separated the Timer A defines from the openMSP430 ones.
Added the "dbg_en" port in order to allow a separate reset of the debug interface.
Added the "core_en" port (when cleared, the CPU will stop execution, the dbg_freeze signal will be set and the aclk & smclk will be stopped).
Renamed "per_wen" to "per_we" to prevent confusion with active low signals.
Removed to missing unused flops when the DBG_EN is not defined (thanks to Mihai contribution).		 olivier.girard 4794d 23h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
105 Removed dummy memory read access for the MOV/PUSH/CALL/RETI instructions.
These were not problematic but this is simply cleaner that way.		 olivier.girard 4810d 00h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
103 Removed the timescale from all RTL files.
Added possibility to exclude the "includes" statements from the RTL.		 olivier.girard 4815d 07h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
86 Update serial debug interface test patterns to make them work with all program memory configurations. olivier.girard 4850d 22h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
67 Added 16x16 Hardware Multiplier. olivier.girard 5178d 09h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
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 5217d 03h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
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 5246d 02h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
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 5246d 03h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
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 5367d 05h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
17 Updated header with SVN info olivier.girard 5393d 00h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
2 Upload complete openMSP430 project to the SVN repository olivier.girard 5428d 00h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
