Rev Log message Author Age Path
299 Modified the status_led.vhd to slow down the DIM50PCT signal to 1/32 instead of 1/2 for use with shift-register based discrete LEDs and added the ability to chain the toggle signal to save on resources as well as synchronize the "toggling" jshamlet 651d 02h /open8_urisc/trunk/
298 Fixed a long-standing bug in the SBC instruction where the 1 wasn't being added to complete the 2's complement of Rn. This was causing off-by-one errors in subtraction and negating carry only subtractions. jshamlet 652d 04h /open8_urisc/trunk/
297 Fixed register map comments jshamlet 942d 12h /open8_urisc/trunk/
296 Removed parallel interface from o8_vector_rx.vhd, modified vector_tx.vhd to use a generic for it's seed value, slight formatting change on o8_elapsed_usec.vhd. jshamlet 951d 04h /open8_urisc/trunk/
295 Undoing previous revision. UART was fine, bug reporter was not. jshamlet 954d 07h /open8_urisc/trunk/
294 Fixed an ancient bug in the parity logic that had the parity inverted. jshamlet 954d 12h /open8_urisc/trunk/
293 Fixed formatting issue in o8_sync_serial where tabs were inserted instead of spaces and fixed column spacing as a result (purely cosmetic) jshamlet 973d 12h /open8_urisc/trunk/
292 Updated the o8_trig_delay entity by:
1) Added a global interrupt enable,
2) Added the ability to trigger on both the pre- and post-arm trigger input
3) Added the ability to read the external input on offset 7		 jshamlet 1044d 12h /open8_urisc/trunk/
291 Added Notepad++ language definition file for the Open8_II ISA jshamlet 1087d 02h /open8_urisc/trunk/
290 Added an additional generic "Rotation_Ignores_Carry" that removes the carry logic from the ROL/ROR instructions such that they now rotate 'normally',
Added an alias for PSR_GP4 named PSR_S, as it is now used to switch the function of the RSP instruction. The internal opcode hasn't changed, but it allows assembly code to use PSR_S or BRS/BNS when performing RSP related operations.		 jshamlet 1087d 02h /open8_urisc/trunk/
