94 BIG update: core now supports different clock speed for the multiplier core, so more performance is posible. currently this version is working in simulation and is being tested on hardware. Changes in this update include:
- changed RAM and memory to support different clocks
- new FIFO that supports dual clock (slightly modified version of generic_fifo's on OpenCores.org)
- parameter C_FIFO_DEPTH is now replace by C_FIFO_AW (address width of the fifo pointers)
- added logic for control signals to cross from one clock domain to another
- updated testbenches and interfaces accordingly
- added log of synthesis of the 2 new fifo's for Xilinx
JonasDC 4033d 20h /mod_sim_exp/trunk/rtl/vhdl/interface/
91 changed interrupt structure of AXI4-Lite interface. Now the interrupt has to be acknowledged by clearing the appropriate interrupt source flag in the control register. JonasDC 4038d 05h /mod_sim_exp/trunk/rtl/vhdl/interface/
90 reverted changes from previous revision, updated AXI version with testbench JonasDC 4039d 19h /mod_sim_exp/trunk/rtl/vhdl/interface/
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4103d 17h /mod_sim_exp/trunk/rtl/vhdl/interface/
86 update on previous JonasDC 4109d 19h /mod_sim_exp/trunk/rtl/vhdl/interface/
85 changed so that reset now also affects slave register JonasDC 4109d 19h /mod_sim_exp/trunk/rtl/vhdl/interface/
84 AXI-Lite interface updated, now tested and verified on Xilinx FPGA
renamed C_DEVICE parameter, because of conflicts with restricted parameter in xilinx XPS
JonasDC 4111d 04h /mod_sim_exp/trunk/rtl/vhdl/interface/
82 added first version of axi-lite interface and testbench for basic axi-lite operations, now under test JonasDC 4130d 00h /mod_sim_exp/trunk/rtl/vhdl/interface/
77 found fault in code, now synthesizes normally JonasDC 4145d 16h /mod_sim_exp/trunk/rtl/vhdl/interface/
74 removed C_NR_OP and C_NR_M from the generic of mod_sim_exp_core and made them contstants, because currently no other values than 4 an 2 resp. are supported/can be implemented. JonasDC 4150d 23h /mod_sim_exp/trunk/rtl/vhdl/interface/
73 updated plb interface, mem_style and device generics added JonasDC 4151d 22h /mod_sim_exp/trunk/rtl/vhdl/interface/
65 updated plb interface, now modulus is selectable and, fifo depth is adjustable.
updated makefile with new sources and update component in package
JonasDC 4160d 17h /mod_sim_exp/trunk/rtl/vhdl/interface/
45 chance run_auto port or mod_sim_exp_core to exp_m JonasDC 4248d 00h /mod_sim_exp/trunk/rtl/vhdl/interface/
44 toplevel of the Modular Simultaneous Exponentiation IP core for the PLB interface JonasDC 4251d 17h /mod_sim_exp/trunk/rtl/vhdl/interface/
43 made the core parameters generics JonasDC 4251d 17h /mod_sim_exp/trunk/rtl/vhdl/interface/
42 corrected wrong library name for mod_sim_exp_pkg JonasDC 4258d 01h /mod_sim_exp/trunk/rtl/vhdl/interface/
40 adjusted core instantiation to new core module name JonasDC 4266d 05h /mod_sim_exp/trunk/rtl/vhdl/interface/
2 First version of VHDL source(working), still contains xilinx primitives and needs to be updated to the OpenCores design rules.. JonasDC 4292d 00h /mod_sim_exp/trunk/rtl/vhdl/interface/
