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	4851d 22h	/amber/
19	Create a configuration log file as part of the synthesis flow. This file is a useful reference to tell the different bitfiles apart.	csantifort	4851d 22h	/amber/
18	Added list of source files and diagram for Amber25 core.	csantifort	4854d 21h	/amber/
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	4855d 20h	/amber/
16	Deleted the old version of the 3-state amber core. Its replaced with amber23. Added the 5-state Amber core.	csantifort	4858d 10h	/amber/
15	Copied amber to amber23, Many system changes to support new amber25 core.	csantifort	4858d 10h	/amber/
14	Re-wrote the behavioral clock generation code to more accurately calculate the sys_clk frequency. The previous version was not producing the correct frequency at higher frequenies due to rounding errors.	csantifort	4859d 22h	/amber/
13	Bug fix - added an extra state to the rx state machine to properly align reading the uart input to the middle of each bit.	csantifort	4859d 22h	/amber/
12	Added INITIALIZE_TO_ZERO parameter to keep instantiation idendical to generic sram models. The parameter is not used in the Xilinx models (they always init to zero) but it used in the generic models.	csantifort	4859d 22h	/amber/
11	Added vmlinux test.	csantifort	4874d 22h	/amber/
10	Removed parameters for unused peruipheral modules	csantifort	4876d 02h	/amber/
9	Change the format of mcr and mrc listings so they exactly match the dissasembly produced by the gnu tools. Write ip instead of r12 in listings.	csantifort	4876d 02h	/amber/
8	Change the value in the ID register to be compatible with the Linux code that parses it and picks a processor type.	csantifort	4876d 02h	/amber/
7	Added instructions to use Veritak simulator. Removed some unused functions from memory_configuration.v.	csantifort	4884d 17h	/amber/
6	Set ignore property for output files	csantifort	4887d 20h	/amber/
5	Deleted two temporary files that should not be in the release.	csantifort	4888d 16h	/amber/
4	Corrected a couple of minor typos	csantifort	4888d 16h	/amber/
3	Added trunk to $AMBER_BASE path	csantifort	4888d 20h	/amber/
2	Baseline release of the Amber 2 core	csantifort	4888d 20h	/amber/
1	The project and the structure was created	root	4915d 23h	/amber/
