134 Add full ASIC support (low-power modes, DFT, ...).
Improved serial debug interface reliability.
olivier.girard 941d 16h /openmsp430/trunk/core/rtl/verilog/omsp_dbg_uart.v
117 To facilitate commercial adoption of the openMSP430, the core has moved to a modified BSD license. olivier.girard 1214d 17h /openmsp430/trunk/core/rtl/verilog/omsp_dbg_uart.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 1248d 16h /openmsp430/trunk/core/rtl/verilog/omsp_dbg_uart.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 1304d 15h /openmsp430/trunk/core/rtl/verilog/omsp_dbg_uart.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 1319d 15h /openmsp430/trunk/core/rtl/verilog/omsp_dbg_uart.v
103 Removed the timescale from all RTL files.
Added possibility to exclude the "includes" statements from the RTL.
olivier.girard 1324d 22h /openmsp430/trunk/core/rtl/verilog/omsp_dbg_uart.v
85 Diverse RTL cosmetic updates. olivier.girard 1360d 16h /openmsp430/trunk/core/rtl/verilog/omsp_dbg_uart.v
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 1513d 17h /openmsp430/trunk/core/rtl/verilog/omsp_dbg_uart.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 1755d 17h /openmsp430/trunk/core/rtl/verilog/omsp_dbg_uart.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 1755d 18h /openmsp430/trunk/core/rtl/verilog/dbg_uart.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 1876d 20h /openmsp430/trunk/core/rtl/verilog/dbg_uart.v
