104 Release of version 1.5, this version supports an independent clock for the multiplier JonasDC 3908d 22h /mod_sim_exp/tags/Release_1.5/rtl/
97 changes in makefile, and fifo's are now also in mod_sim_exp library JonasDC 3944d 03h /mod_sim_exp/trunk/rtl/
95 new control logic for the core, allow for greater frequencies for the multiplier.
changes:
- autorun_cntrl: the bit selection for the exponents is now implemented with a shift register in stead of a mux. credits to Geoffrey Ottoy for new design structure.
- mont_cntrl: gave the databus from and to the RAM more time to settle. data now has 3 clocks to get to its destination.		 JonasDC 3945d 03h /mod_sim_exp/trunk/rtl/
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 3957d 23h /mod_sim_exp/trunk/rtl/
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 3962d 08h /mod_sim_exp/trunk/rtl/
90 reverted changes from previous revision, updated AXI version with testbench JonasDC 3963d 22h /mod_sim_exp/trunk/rtl/
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4027d 20h /mod_sim_exp/trunk/rtl/
86 update on previous JonasDC 4033d 22h /mod_sim_exp/trunk/rtl/
85 changed so that reset now also affects slave register JonasDC 4033d 22h /mod_sim_exp/trunk/rtl/
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 4035d 07h /mod_sim_exp/trunk/rtl/
83 now using values from mod_sim_exp_pkg instead of direct entity JonasDC 4037d 07h /mod_sim_exp/trunk/rtl/
82 added first version of axi-lite interface and testbench for basic axi-lite operations, now under test JonasDC 4054d 03h /mod_sim_exp/trunk/rtl/
81 updated files, now using the components of the mod_sim_exp_pkg instead of direct entity declaration JonasDC 4054d 04h /mod_sim_exp/trunk/rtl/
77 found fault in code, now synthesizes normally JonasDC 4069d 19h /mod_sim_exp/trunk/rtl/
75 made rw_address a vector of a fixed width JonasDC 4072d 06h /mod_sim_exp/trunk/rtl/
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 4075d 02h /mod_sim_exp/trunk/rtl/
73 updated plb interface, mem_style and device generics added JonasDC 4076d 01h /mod_sim_exp/trunk/rtl/
69 big update, the mod_sim_exp core now has a selectable ram structure. a generic ram that should be usable in any fpga, a asymmetric ram that is usable for some devices of altera or xilinx and uses less resources. JonasDC 4077d 01h /mod_sim_exp/trunk/rtl/
67 added memory modules for modulus and operands for FPGA's that support asymmetric memory inferring. JonasDC 4077d 04h /mod_sim_exp/trunk/rtl/
66 added asymmetric ram structures to support a more performant ramstyle.
defined for xilinx and altera, not tested with other tools.		 JonasDC 4077d 05h /mod_sim_exp/trunk/rtl/
65 updated plb interface, now modulus is selectable and, fifo depth is adjustable.
updated makefile with new sources and update component in package		 JonasDC 4084d 20h /mod_sim_exp/trunk/rtl/
63 now using a generic description of the ram for the memory. the core now should synthesize for al fpga's, no device specific code anymore. tested and synthesizes for altera and xilinx JonasDC 4085d 02h /mod_sim_exp/trunk/rtl/
62 not used anymore JonasDC 4085d 05h /mod_sim_exp/trunk/rtl/
61 updated comments, added optional altera constraint JonasDC 4085d 05h /mod_sim_exp/trunk/rtl/
60 generic version of the fifo, not device specific anymore, uses dpram_generic
updated comments of RAM templates.		 JonasDC 4087d 19h /mod_sim_exp/trunk/rtl/
59 added templates that correctly infer RAM, for dual port en true dual port RAM
added general functions file, (used in the two RAM templates)		 JonasDC 4087d 19h /mod_sim_exp/trunk/rtl/
55 updated resource usage in comments JonasDC 4091d 19h /mod_sim_exp/trunk/rtl/
54 generic fifo design: correctrly inferred by xilinx and altera JonasDC 4091d 19h /mod_sim_exp/trunk/rtl/
53 correctly inferred ram for altera dual port ram JonasDC 4092d 02h /mod_sim_exp/trunk/rtl/
52 correct inferring of blockram, no additional resources. JonasDC 4092d 02h /mod_sim_exp/trunk/rtl/
