94 Added signal from ex stage to register lock unit for clearing all register locks
when a branch is executed.

93 Changed behavior on branch. Current PC is immeadiately taken from ex stage alu result. jlechner 6465d 13h /
92 Added logic for inserting a nop instruction when the pipeline is cleared. jlechner 6465d 14h /
91 - Computed new SR values from ALU result. cwalter 6465d 14h /
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 6465d 14h /
89 Added input signal for clearing all register locks. jlechner 6465d 14h /
88 - Added new patch for assembler. cwalter 6465d 14h /
87 no message cwalter 6465d 14h /
86 - Added new example for a more complex loop. cwalter 6465d 14h /
85 Removed PC reset on clear_in signal. Clear_in only comes together with a branch, so it is sufficient

84 - PC value was wrong. cwalter 6465d 17h /
83 - sr_enable and lr_enable where incorrect. cwalter 6465d 17h /
