98 - Applied indenting tool. cwalter 6374d 20h /rise/trunk/vhdl/
97 Fixed bug: only set branch and clear signals if branch is actually executed. jlechner 6374d 21h /rise/trunk/vhdl/
96 - SR register is now computed in ALU stage. cwalter 6374d 22h /rise/trunk/vhdl/
95 - Write back now only updates SR in case of a LOAD. cwalter 6374d 22h /rise/trunk/vhdl/
94 Added signal from ex stage to register lock unit for clearing all register locks
when a branch is executed.
jlechner 6374d 22h /rise/trunk/vhdl/
93 Changed behavior on branch. Current PC is immeadiately taken from ex stage alu result. jlechner 6374d 22h /rise/trunk/vhdl/
92 Added logic for inserting a nop instruction when the pipeline is cleared. jlechner 6374d 22h /rise/trunk/vhdl/
91 - Computed new SR values from ALU result. cwalter 6374d 22h /rise/trunk/vhdl/
90 Added output signal for clearing all register locks when a branch instruction is executed.
This is necessary because the id stage could have locked registers for an instruction
that is cleared out of the pipeline due to the branch.
jlechner 6374d 22h /rise/trunk/vhdl/
89 Added input signal for clearing all register locks. jlechner 6374d 22h /rise/trunk/vhdl/
86 - Added new example for a more complex loop. cwalter 6374d 23h /rise/trunk/vhdl/
85 Removed PC reset on clear_in signal. Clear_in only comes together with a branch, so it is sufficient
branch immediately.
jlechner 6375d 01h /rise/trunk/vhdl/
84 - PC value was wrong. cwalter 6375d 01h /rise/trunk/vhdl/
83 - sr_enable and lr_enable where incorrect. cwalter 6375d 01h /rise/trunk/vhdl/
80 - Fixed testbench to work with new barrel shifter. cwalter 6375d 02h /rise/trunk/vhdl/
79 - Added barrel shifter. cwalter 6375d 02h /rise/trunk/vhdl/
78 Added stall_in to sensitivity list. jlechner 6375d 02h /rise/trunk/vhdl/
77 - Fixed case. cwalter 6375d 02h /rise/trunk/vhdl/
76 - Changed order of some statements to improve readability. cwalter 6375d 02h /rise/trunk/vhdl/
75 - Added barrel shifter implementation. cwalter 6375d 02h /rise/trunk/vhdl/
