83 Fixed bug with carry bit - now only use the carry bit as an input to specific instruments that use it - add with carry and subtract with carry csantifort 3363d 17h /amber/trunk/hw/tests/
82 Fixed overflag bug, ldmia user regs bug and status_bits_mode set on non-ececuting command bug csantifort 3377d 05h /amber/trunk/hw/tests/
70 The mlas_bug testcase tried to use stack without setting stack pointer
register, causing unpredictable behavoiur.
The patch uses an expilict stack area for the test.

60 Bug fix; removed a combinational loop from the a25_decode logic. csantifort 4568d 08h /amber/trunk/hw/tests/
56 Remove the timeouts file from svn. Its an output file and gets now just gets created automatically
when sims are run for the first time.		 csantifort 4638d 09h /amber/trunk/hw/tests/
54 Bug fix for bug reported by Botao Lee. The mode bits in the decode stage did not change immediately
after a mode switch from a teqp instruction, but 1 cycle later. This meant the wrong set of registers
was selected for writing to for 1 clock cycle.		 csantifort 4655d 08h /amber/trunk/hw/tests/
50 Revert to previous version csantifort 4711d 06h /amber/trunk/hw/tests/
49 Added a note n how to change timeouts csantifort 4711d 06h /amber/trunk/hw/tests/
48 Fixed a bug in linux that caused the os to not return to the running application after an interrupt.
Hello-world now runs stand-alone again.
Added initrd-200k-dhry, a disk image that uses the dhry program for init.		 csantifort 4715d 13h /amber/trunk/hw/tests/
40 Added wishbone bus jitter testing option.
Cleaned up waveform log .do files, now seperate files for a23 and a25 cores.
Added vmlinux executable elf file for running on hardware.		 csantifort 4767d 06h /amber/trunk/hw/tests/
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 4770d 05h /amber/trunk/hw/tests/
35 Amber25 improvements:
Use 128-bit wishbone bus, instead of 32-bit to reduce cache miss fetch times
Use a fast barrel shifter for shifts between 0 and 4 to improve timing
Use a 2 cycle full barrel shifter for complex shifts		 csantifort 4771d 13h /amber/trunk/hw/tests/
20 Added feature to A25 core to directly use a read value from the write back stage
to reduce the stall to 1 cycle when there is a register conflict with the
following instruction. This increases performance by about 3%.		 csantifort 4856d 12h /amber/trunk/hw/tests/
17 amber25 core bug fix. The return address for irq interrupts was off by 4 bytes
when the interrupt occurred during a stm instruction with the following instruction
having some register conflicts. Added test irq_stm to catch the bug.
Cleaned up some header descriptions		 csantifort 4860d 10h /amber/trunk/hw/tests/
15 Copied amber to amber23, Many system changes to support new amber25 core. csantifort 4863d 01h /amber/trunk/hw/tests/
11 Added vmlinux test. csantifort 4879d 13h /amber/trunk/hw/tests/
6 Set ignore property for output files csantifort 4892d 10h /amber/trunk/hw/tests/
2 Baseline release of the Amber 2 core csantifort 4893d 11h /amber/trunk/hw/tests/
