Rev Log message Author Age Path
306 Moved REINIT_TASK_TABLE_PTR call to INITIALIZE_TASK_STACK jshamlet 846d 21h /open8_urisc/trunk
305 More code cleanup - rearranged macros and moved stack init to separate macro jshamlet 846d 22h /open8_urisc/trunk
304 Modified TASK_SETUP to use the same macros as the rest of the task switcher and cleaned up the code some more. jshamlet 846d 22h /open8_urisc/trunk
303 Fixed working, but "incorrect" code (constants were right, but were named incorrectly jshamlet 847d 09h /open8_urisc/trunk
302 Corrected issue where register state wasn't being preserved for user function stubs,
Modified FREEMEM calc to use the region size constant.		 jshamlet 847d 10h /open8_urisc/trunk
301 Adding actual task manager files jshamlet 849d 07h /open8_urisc/trunk
300 Adding core task manager assembly jshamlet 849d 07h /open8_urisc/trunk
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 851d 07h /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 852d 10h /open8_urisc/trunk
297 Fixed register map comments jshamlet 1142d 18h /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 1151d 10h /open8_urisc/trunk
295 Undoing previous revision. UART was fine, bug reporter was not. jshamlet 1154d 13h /open8_urisc/trunk
294 Fixed an ancient bug in the parity logic that had the parity inverted. jshamlet 1154d 18h /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 1173d 18h /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 1244d 17h /open8_urisc/trunk
291 Added Notepad++ language definition file for the Open8_II ISA jshamlet 1287d 08h /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 1287d 08h /open8_urisc/trunk
289 Added back the delay for the cursor home command, since it is slow on most Hitachi compatible LCD panels. jshamlet 1304d 18h /open8_urisc/trunk
288 Removed hard-wired R/Wn output and replaced it with a note that the R/Wn line must be tied low either in firmware or on the board. jshamlet 1305d 15h /open8_urisc/trunk
287 Fixed mangled comments and revisioning dates. jshamlet 1306d 14h /open8_urisc/trunk
