97 changes in makefile, and fifo's are now also in mod_sim_exp library JonasDC 4014d 07h /mod_sim_exp/trunk/rtl/vhdl/core
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 4015d 08h /mod_sim_exp/trunk/rtl/vhdl/core
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 4028d 04h /mod_sim_exp/trunk/rtl/vhdl/core
90 reverted changes from previous revision, updated AXI version with testbench JonasDC 4034d 03h /mod_sim_exp/trunk/rtl/vhdl/core
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4098d 01h /mod_sim_exp/trunk/rtl/vhdl/core
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 4105d 11h /mod_sim_exp/trunk/rtl/vhdl/core
83 now using values from mod_sim_exp_pkg instead of direct entity JonasDC 4107d 12h /mod_sim_exp/trunk/rtl/vhdl/core
81 updated files, now using the components of the mod_sim_exp_pkg instead of direct entity declaration JonasDC 4124d 08h /mod_sim_exp/trunk/rtl/vhdl/core
75 made rw_address a vector of a fixed width JonasDC 4142d 10h /mod_sim_exp/trunk/rtl/vhdl/core
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 4145d 06h /mod_sim_exp/trunk/rtl/vhdl/core
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 4147d 06h /mod_sim_exp/trunk/rtl/vhdl/core
67 added memory modules for modulus and operands for FPGA's that support asymmetric memory inferring. JonasDC 4147d 09h /mod_sim_exp/trunk/rtl/vhdl/core
65 updated plb interface, now modulus is selectable and, fifo depth is adjustable.
updated makefile with new sources and update component in package
JonasDC 4155d 01h /mod_sim_exp/trunk/rtl/vhdl/core
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 4155d 06h /mod_sim_exp/trunk/rtl/vhdl/core
60 generic version of the fifo, not device specific anymore, uses dpram_generic
updated comments of RAM templates.
JonasDC 4157d 23h /mod_sim_exp/trunk/rtl/vhdl/core
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 4158d 00h /mod_sim_exp/trunk/rtl/vhdl/core
55 updated resource usage in comments JonasDC 4161d 23h /mod_sim_exp/trunk/rtl/vhdl/core
54 generic fifo design: correctrly inferred by xilinx and altera JonasDC 4162d 00h /mod_sim_exp/trunk/rtl/vhdl/core
45 chance run_auto port or mod_sim_exp_core to exp_m JonasDC 4242d 07h /mod_sim_exp/trunk/rtl/vhdl/core
43 made the core parameters generics JonasDC 4246d 01h /mod_sim_exp/trunk/rtl/vhdl/core
