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 5015d 18h /amber/
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 5036d 19h /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 5036d 19h /amber/
18 Added list of source files and diagram for Amber25 core. csantifort 5039d 18h /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 5040d 17h /amber/
16 Deleted the old version of the 3-state amber core. Its replaced with amber23.
Added the 5-state Amber core.
csantifort 5043d 07h /amber/
15 Copied amber to amber23, Many system changes to support new amber25 core. csantifort 5043d 07h /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 5044d 19h /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 5044d 19h /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 5044d 20h /amber/
11 Added vmlinux test. csantifort 5059d 20h /amber/
10 Removed parameters for unused peruipheral modules csantifort 5060d 23h /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 5060d 23h /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 5060d 23h /amber/
7 Added instructions to use Veritak simulator.
Removed some unused functions from memory_configuration.v.
csantifort 5069d 14h /amber/
6 Set ignore property for output files csantifort 5072d 17h /amber/
5 Deleted two temporary files that should not be in the release. csantifort 5073d 13h /amber/
