82	Fixed overflag bug, ldmia user regs bug and status_bits_mode set on non-ececuting command bug	csantifort	3541d 19h	/amber/trunk/hw/vlog/amber23/a23_barrel_shift_fpga.v
74	The patch implements barrel shifter using rotate as a main primitive. The design was optimized for Altera Cyclone III FPGA and can be reused with other FPGA vendors and products. The patch integrates the FPGA-optimized barrel shifter into the Amber 23 core when it is build for Altera FPGA. The patch reduces footprint from 1178 to 339 LEs keeping Fmax at 57-60 MHz.
