38	support 128-bit wishbone now used for a25 core	csantifort	4799d 18h	/amber/trunk
37	128-bit wide boot memory module	csantifort	4800d 17h	/amber/trunk
36	Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus	csantifort	4800d 17h	/amber/trunk
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	4802d 01h	/amber/trunk
34	Tweaked strcpy function to speed it up slightly	csantifort	4802d 22h	/amber/trunk
33	Fixed bug in div assembly function. Handles negative numbers correctly. Fixed bug in printf function, negative numbers now print correctly.	csantifort	4803d 18h	/amber/trunk
32	Added clock cycle counting register to test_module to support dhrystone performance measurement	csantifort	4804d 18h	/amber/trunk
31	Added dhrystone benchmark test	csantifort	4804d 18h	/amber/trunk
30	Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays	csantifort	4818d 01h	/amber/trunk
29	Use lgo command for saving waveforms in modelsim	csantifort	4819d 18h	/amber/trunk
28	Moved function prototypes to .h file	csantifort	4819d 19h	/amber/trunk
27	Got working with cadence nc simulator	csantifort	4853d 02h	/amber/trunk
26	Added wish list	csantifort	4858d 02h	/amber/trunk
25	Bug fix: boot-loader.mem became larger that the allowed 8k byte boot mem size. Removed a struct in elfsplitter.c thats only used for debug - this reduced boot-loader.mem enough so that it fits again. Tidy up: Removed a debug message from hw/tools/run.sh	csantifort	4859d 23h	/amber/trunk
24	Added instructions how to build Linux kernel from source files	csantifort	4861d 23h	/amber/trunk
23	Split the source files list into a Vertex-6 only list and a Spartan-6 only list. That way users don;t need to delete files from the list manually if they only have a setup for one of the FPGA types.	csantifort	4862d 00h	/amber/trunk
22	Added files and instructions to enable the building of the vmlinux image from the kernel source files.	csantifort	4866d 00h	/amber/trunk
21	Fixed bug in the conditions to create the FPGA configuration log file. I added the creation of the log file in the last release, but the way it was implemented was causing the Makefile to always rebuild from the start.	csantifort	4866d 00h	/amber/trunk
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	4887d 00h	/amber/trunk
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	4887d 01h	/amber/trunk
18	Added list of source files and diagram for Amber25 core.	csantifort	4889d 23h	/amber/trunk
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	4890d 22h	/amber/trunk
16	Deleted the old version of the 3-state amber core. Its replaced with amber23. Added the 5-state Amber core.	csantifort	4893d 13h	/amber/trunk
15	Copied amber to amber23, Many system changes to support new amber25 core.	csantifort	4893d 13h	/amber/trunk
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	4895d 01h	/amber/trunk
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	4895d 01h	/amber/trunk
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	4895d 01h	/amber/trunk
11	Added vmlinux test.	csantifort	4910d 01h	/amber/trunk
10	Removed parameters for unused peruipheral modules	csantifort	4911d 05h	/amber/trunk
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	4911d 05h	/amber/trunk
