Age	Commit message (Collapse)	Author
2015-06-29	Added testcases with 1024 bit and 2048 bit modulus, mem and short exponents.	Joachim Strömbergson

2015-06-27	Fixed the license in the header.	Joachim Strömbergson

2015-06-26	Added test case with small exponent and modulus, message that requires ↵	Joachim Strömbergson
	padding to work correctly.
2015-06-26	Changed modexp core to use explicit exponent length to allow removal of ↵	Joachim Strömbergson
	padding of exponent and improving performance. Updated testbenches to match the changed lengths inside the device under test.
2015-06-26	Removed extra digit in test case KAT that had creeped in.	Joachim Strömbergson

2015-06-24	Fused the s_mem init loop into the adder loop.	Joachim Strömbergson

2015-06-24	Small improvement in report of test result.	Joachim Strömbergson

2015-06-24	(1) Untangled the word index address generator from the product logic. (2) ↵	Joachim Strömbergson
	Updated the montprod TB to match changed FSM states in montprod.
2015-06-22	Removing stale states in FSM.	Joachim Strömbergson

2015-06-17	(1) Collapsed the sm and sa adder states. Thisimoproves performance for ↵	Joachim Strömbergson
	modexp with 3%. (2) Updated montprod testbench to not use the now removed states. (3) Minor code cleanup to make it easier to work with for further improvements.
2015-06-16	Fixed final big testcase to match python model.	Joachim Strömbergson

2015-06-16	Collapsing cycles for loop counter. Updating testbench to match removed cycles.	Joachim Strömbergson

2015-06-16	Fixed non trivial yet fairly short testcases.	Joachim Strömbergson

2015-06-15	Fixed baseline.	Joachim Strömbergson

2015-06-10	More cleanup. Adding a lot of compile flags to be able to silence the testbench.	Joachim Strömbergson

2015-06-10	Added cycle counter to the montprod testbench to measure the execution time.	Joachim Strömbergson

2015-06-03	Adding the encipher/verify test case with 1024 bit RSA key by Rob.	Joachim Strömbergson

2015-06-02	Adding sign testcase with 1024 bit operands from real RSA key.	Joachim Strömbergson

2015-06-02	Refactored into core and top.	Joachim Strömbergson

2015-05-24	Fixed names.	Joachim Strömbergson

2015-05-24	Adding two more signing test cases with e=65537 and explicit lengths for ↵	Joachim Strömbergson
	exponent and modulus, message.
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	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.
2015-04-27	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.
2015-04-20	Adding testbench for the residue calculator.	Joachim Strömbergson

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