core/pkey/ecdsa256 - Scalar base point multiplier for ECDSA curve P-256

Age	Commit message (Collapse)	Author
2018-12-19	* Rewritten from scratch, uses the same hardware architecture as the Ed25519HEAD master	Pavel V. Shatov (Meister)
	core for better timing performance * Removed custom modular inversion sub-module, now uses micro-coded modular inversion routine based on Fermat's little theorem (~10% faster) * Uses math primitives from core/lib * Added randomized test vector (see user/shatov/ecdsa_fpga_model/test_vectors/)
2018-09-06	Replicated certain FSM-related signals for better placement and routing.	Pavel V. Shatov (Meister)

2018-09-06	Turned ROMs into distributed memories, otherwise synthesizer was combining them	Pavel V. Shatov (Meister)
	into a single block ROM which hurt placement and routing.
2018-04-01	Fixed coordinates of the internally stored point H = 2 * G.	Pavel V. Shatov (Meister)

2017-03-07	Promote to a repository in the core tree.	Rob Austein
	Change name of reset signal from rst_n to reset_n for consistancy with other Cryptech cores. Code common between this core and the ecdsa384 core split out into a separate library repository. Minor cleanup (Windows-isms, indentation).
2017-02-12	Various clean-ups	Pavel V. Shatov (Meister)
	* Added sample C program for STM32 to test the core in hardware * Parametrized math modules are now instantiated with explicit operand width for clarify (previously relied on default parameter values in underlying modules) * Fixed some comments
2016-10-31	Initial commit of base point multiplier core for ECDSA curve P-256.	Pavel V. Shatov (Meister)
