9d953421d8 After a quick check, added a couple of other _delegate initialisations. I should probably find a way to template this. 2017-08-01 07:07:43 -04:00

4abd62e62b Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty. 2017-07-27 22:05:29 -04:00

b3ae920746 Converted the DPLL and disk controller classes to be ClockReceivers. 2017-07-24 21:04:47 -04:00

163c0f1b44 Ensured offset means exactly one thing. 2017-07-21 20:58:17 -04:00

e5188a60dc Settled on the new average-of-length approach to a PLL window sizing, eliminating the old errors-of-phase approach. Since it anchors automatically to the original target clocks per bit, killed the explicit mention of a tolerance. 2017-07-16 19:03:50 -04:00

e71d13c090 With the new PLL implementation, switching to a deeper window size returns the Acorn tape parser to: working. 2017-07-16 17:12:12 -04:00

51177e4e1f Attempted a different implementation of the PLL, that responds to changes only once. 2017-07-16 16:49:04 -04:00

4489f120f9 Eliminated foolish double indirection on phase history. 2017-07-15 22:40:38 -04:00

e01f3f06c8 Completed curly bracket movement. 2017-03-26 14:34:47 -04:00

0dc2aa6454 Commuted all of 'Storage' other than 'Tape' to postfix underscores. 2016-12-03 11:59:28 -05:00

d832e5e10d Reduced 1540 PLL to running at 4Mhz. Which is possibly correct (?) Made minor change to avoid divide if possible. 2016-08-02 21:28:50 -04:00

5c1614ce7b Attempted to simplify, very slightly. 2016-07-28 14:35:39 -04:00

015cea494d Switched to a much-more straightforward PLL. I think I'm just fiddling now rather than moving forwards. Probably time to move on? 2016-07-28 11:32:14 -04:00

e061e849d4 Had a second bash at the PLL. Probably I should read some of the literature. 2016-07-27 16:24:24 -04:00

6afd619791 Eliminated floating point arithmetic. 2016-07-14 19:47:00 -04:00

6b4fec37ff Moved down to a single divide. 2016-07-14 19:45:08 -04:00
Thomas Harte
481475a0f4 Switched to a full-on linear regression. Which causes the current tests to pass. 2016-07-14 19:42:01 -04:00

6d6b26b99f Actually made things worse. 2016-07-14 07:32:27 -04:00

d8d3464c56 Made a quick-hack attempt at PLL synchronisation. Which doesn't work. 2016-07-14 07:31:23 -04:00

d1fe07f14d Added test of perfect DPLL input timing. 2016-07-12 21:42:23 -04:00

94db45456e Started sketching out the basic form here, albeit that it doesn't yet do _the only thing it advertises itself as useful for_. 2016-07-12 20:23:56 -04:00

75d95c0bc0 Sketched out an interface for a digial PLL. Not persuaded yet. Baby steps. 2016-07-11 22:12:58 -04:00
