2015-05-24	Adding two more signing test cases with e=65537 and explicit lengths for ↵	Joachim Strömbergson
	exponent and modulus, message.

2015-05-22	Removed file that should not have been in the repo.	Joachim Strömbergson

2015-05-21	Added internal cycle counter. Added API addresses to extract cycle counter ↵	Joachim Strömbergson
	value. Moved reset of start reg to beginning of FSM.
2015-05-20	(1) Removed unneeded default state. (2) Cleanup of testbench and added a ↵	Joachim Strömbergson
	bigger test case.
2015-05-20	Adding new memories with internal pointers.	Joachim Strömbergson

2015-05-20	Changed to using modexp length register and removed the common length register.	Joachim Strömbergson

2015-05-19	Updated TB to use access ports. Added missing invalidate of residue when ↵	Joachim Strömbergson
	modulus is updated. Minor cleanup.
2015-05-08	Fixed RH operand size.	Joachim Strömbergson

2015-04-27	Updated header with info about bit lengths supported.	Joachim Strömbergson

2015-04-27	Adding localparam for debugging that had gone missing.	Joachim Strömbergson

2015-04-27	Updating modexp core to v 0.50. This version contains a working core that ↵	Joachim Strömbergson
	can perform sign and verify with big keys/values. The core builds ok in Altera and Xilinx FPGA tools. This commit also includes a new testgenerator capable of generating testbench for modexp with autgenerated test data of different lengths. The README has been updated with status and implementation results in for different FPGA devices.
2015-04-24	(1) Adding auto generated testbench for verilog. (2) Update of the test ↵	Joachim Strömbergson
	generator. (3) Update of the Makefile to run test generator.
2015-04-23	Adding a generator for tests to the modexp model and core.	Joachim Strömbergson

2015-04-21	Fixed incorrect types.	Joachim Strömbergson

2015-04-21	Adding more targets for building, linting and simulating submodules.	Joachim Strömbergson

2015-04-21	Update of modexp to include more of the integration of residue calculator. ↵	Joachim Strömbergson
	Update of shl and shr to simplify code. shl and shr could be replaced by functions.
2015-04-20	Adding testbench for the residue calculator.	Joachim Strömbergson

2015-04-20	(1) Modexp with better API. (2) Adding working residue module. (3) Adding ↵	Joachim Strömbergson
	new shift32 with carry module needed by the residue module.
2015-04-20	Updated to correct license file.	Joachim Strömbergson

2015-04-20	Updated Makefile with residue module targets. Updated the license info.	Joachim Strömbergson

2015-04-20	Updated README with more info about the modexp core and status.	Joachim Strömbergson

2015-04-20	Adding gitignore to cleanup status checks.	Joachim Strömbergson

2015-04-13	Adding testbenches for montprod and modexp. The montprod tb has testcases ↵	Joachim Strömbergson
	for up to 1024 bit values.
2015-04-13	Adding makefile for linting and for building sim targets.	Joachim Strömbergson

2015-04-13	Adding initial versions of rtl for modexp. Montgomery multiplication works ↵	Joachim Strömbergson
	for 8192 bit operands. Modexp can build, but lacks proper control and residue generator. Memories has been tested to match block memories in Xilinx and Altera FPGAs.
