202 Add DMA interface support + LINT cleanup olivier.girard 3641d 21h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
200 Major verificaiton and benchmark update to support both MSPGCC and RedHat/TI GCC toolchains. olivier.girard 3802d 21h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
192 Number of supported IRQs is now configurable to 14 (default), 30 or 62. olivier.girard 4202d 22h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
175 Update hardware breakpoint unit with the followings:
- fixed hardware breakpoint bug with CALL instructions.
- modified data read watchpoint behavior to also trigger with read/modify/write instructions.
- removed unused ports.		 olivier.girard 4523d 21h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
154 The serial debug interface now supports the I2C protocol (in addition to the UART) olivier.girard 4630d 22h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
134 Add full ASIC support (low-power modes, DFT, ...).
Improved serial debug interface reliability.		 olivier.girard 4837d 22h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
117 To facilitate commercial adoption of the openMSP430, the core has moved to a modified BSD license. olivier.girard 5110d 23h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
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 5144d 22h /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 5200d 21h /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 5215d 22h /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 5221d 04h /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 5256d 20h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
67 Added 16x16 Hardware Multiplier. olivier.girard 5584d 07h /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 5623d 00h /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 5652d 00h /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 5652d 00h /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 5773d 02h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
17 Updated header with SVN info olivier.girard 5798d 21h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
2 Upload complete openMSP430 project to the SVN repository olivier.girard 5833d 21h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
