Age	Commit message (Collapse)	Author
2019-06-09	Clarified the cycle times that was confusing regarding key expansion. Fixed ↵HEAD master	Joachim Strömbergson
	minor speling errror.
2019-02-08	spaces/tabs. Grrr.	Joachim Strömbergson

2019-02-08	Added missing flags for building and linting.	Joachim Strömbergson

2019-01-15	Bump the version number, because new code.	Paul Selkirk

2019-01-09	Clean-up ill-advised fork of core/cipher/aes.	Rob Austein
	For reasons which seemed to make sense at the time but of which he has long since repented, Joachim forked the core/cipher/aes repository to a new core/cipher/aes_speed repository rather than just branching. After some discussion, we decided to repair this. Summary of repair: 1) Create new empty repository, add both core/cipher/aes and core/cipher/aes_speed as remotes. 2) Identify commit in core/cipher/aes from which core/cipher/aes_speed was forked (determined by log inspection and comparison of the diff size between commits in aes/master and aes_speed/master). 3) Splice the trees using a terrifying git command: git checkout -b master aes_speed/master git filter-branch \ --commit-filter 'git commit-tree -S${keyid} "$@"' \ --parent-filter "sed 's/^\$/-p ${fork_point}/'" \ master where ${keyid} is the GPG key ID of the person doing the repair work and ${fork_point} is the ID of the commit in core/cipher/aes from which core/cipher/aes_speed was forked. 4) Merge the filtered master branch created above to aes/master with `-s our` so that the master branch going forward will be the content from core/cipher/aes_speed.
2018-10-23	For completeness sake added API hardening to the aes core too. The AES core ↵	Joachim Strömbergson
	has been replaced with the aes_speed core but is still available as a separate repo.
2018-10-16	Added the regs missing in reset also in the old aes core.	Joachim Strömbergson

2018-10-03	Adding restriction to the API to only allow writes to controlling registers. ↵	Joachim Strömbergson
	This fixes CT-01-002 FPGA.
2018-10-03	Adding testcase that tests the mangling of aes operations by switching from ↵	Joachim Strömbergson
	encipher to decipher mid-operation.
2018-10-02	Reading AES result will be zero when ready is not set.	Joachim Strömbergson

2018-09-27	Added missing reset of registers. This fixes CT-01-001 FPGA.	Joachim Strömbergson

2018-07-04	(1) Added NIST KWP test to core. (2) Moved all other tests in core tb to a ↵	Joachim Strömbergson
	separate task. (3) Minor cleanup in top tb.
2018-07-04	Added a test case for AES with test vectors from processing NIST KWP keywrap ↵	Joachim Strömbergson
	operation. This verifies that we are using the AES core correctly in the keywrap core. But it is a new test vector for AES too.
2018-06-14	Added CC_FLAGS and LINT_FLAGS.	Joachim Strömbergson

2018-05-26	Shaved off another cycle for block processing.	Joachim Strömbergson

2018-05-22	Added missing implementation results for Xilinx Artix7.	Joachim Strömbergson

2018-05-22	Updated README with latest implementation results and status for the core.	Joachim Strömbergson

2018-05-22	Minor cleanup of states and register sizes.	Joachim Strömbergson

2018-05-22	Combined all AES round operations into a single operation for a round.	Joachim Strömbergson

2018-05-22	Added wait_ready task to allow test cases to wait for the core to complete ↵	Joachim Strömbergson
	an operation. This makes it possible to measure cycles for an operation.
2018-05-22	Polished the wait_ready task to use defined bit index.	Joachim Strömbergson

2018-05-22	Updated README with implementation results.	Joachim Strömbergson

2018-05-21	Updated core status and implementation details.	Joachim Strömbergson

2018-05-21	Increased number of inverse S-boxes to 16 and removed S-box scheduling.	Joachim Strömbergson

2018-05-21	Cleaned up redundant wires.	Joachim Strömbergson

2018-05-21	Moved the Sbox used for key expansion into the key_mem.	Joachim Strömbergson

2018-05-21	Removed the sbox word mux. Removed ports for sbox access in the encipher ↵	Joachim Strömbergson
	datapath since it now has its own sboxes.
2018-05-21	Removed the sword counter since it is not needed.	Joachim Strömbergson

2018-05-21	Connected the new S-boxes and collapsed the SubBytes operation into one ↵	Joachim Strömbergson
	cycle. This provides a speedup for Encipher with 2.1x.
2018-05-21	Adding 16 S-boxes to the encipher datapath.	Joachim Strömbergson

2018-05-21	Adding task to wait for ready to be set. This allows us to measure the ↵	Joachim Strömbergson
	number of cycles spent doing operations.
2018-05-21	Adding inital version of AES core optimized for performance.	Joachim Strömbergson

2017-12-15	Adding the error port that went missing. Sloppy.	Joachim Strömbergson

2017-12-14	Synced the AES core rtl and testbench to github. The updates does not add or ↵	Joachim Strömbergson
	modify any functionality, but silence a lot of warnings, reduce code size.
2017-12-14	Adding support for linting the AES core.	Joachim Strömbergson

2015-12-13	whack copyrights	Paul Selkirk

2015-10-02	Fixing text error in comment.	Joachim Strömbergson

2015-07-17	fix CORE_VERSION to match what we think it should be	Paul Selkirk

2015-05-28	Corrected where config bits are.	Joachim Strömbergson

2015-05-16	(1) Changed name and version to reflect that it is not only AES-128 and that ↵	Joachim Strömbergson
	the core is fairly close to done. (2) Moved counter update.
2015-05-04	(1) Changed ordet of status and config addresses to conform to what we have ↵	Joachim Strömbergson
	in other cores. (2) Changed to localparam to stop polluting namespace.
2014-11-28	Reworked the sbox and inverse sbox. Slighly smaller design and much shorter ↵	Joachim Strömbergson
	source files.
2014-11-28	Removed obsolete target.	Joachim Strömbergson

2014-11-27	Adding Makefile for building simulation targets.	Joachim Strömbergson

2014-11-27	Adding Python models for AES as well as key expansion and rcon.	Joachim Strömbergson

2014-11-27	Adding testbenchs.	Joachim Strömbergson

2014-11-27	Adding RTL source files for the AES core.	Joachim Strömbergson

2014-11-27	Adding license file too.	Joachim Strömbergson
