  • 47d53ecf78 Fix performance by using pointer tricks for ADD. 20% faster line drawing hugova 2025-03-24 17:07:14 +01:00
  • de2d597612 Change of starting condition for potential testing purposes of another person hugova 2025-03-09 23:53:33 +01:00
  • a617d91183 Change 4 spaces indenting to 8 and add string for emacs to understand indenting rules hugova 2025-03-09 23:43:59 +01:00
  • 36610e7df8 Made shure that run.sh also create a listing file for debuging and stuff hugova 2025-03-09 20:57:46 +01:00
  • 09b8a33e09 Adding of 16-bit arithmatic macro variants for X and A as input hugova 2025-03-07 00:48:13 +01:00
  • 0797e69106 Add all optimisations done on line_down to line_down_inv. DIx a problem that the pixel was drawin a bit to late in the loop on line_down. hugova 2025-03-06 01:50:37 +01:00
  • ecc138f2bc Redused number of instructions but to small a diffrence to messure with current test hugova 2025-03-06 00:59:29 +01:00
  • 9694d8d55b Redused paint_pixel to 1 call in draw line hugova 2025-03-05 22:42:00 +01:00
  • 76f29f6b81 Performance improvment in test by 0.1s. Mady by better arithmatic for *40 in draw_pixel and fast_unsafe parameter for most macros hugova 2025-03-05 21:02:54 +01:00
  • 982b6c7ea6 A fix for the timer to work by making it start with value 1. It do not increment from 0! hugova 2025-03-05 01:27:37 +01:00
  • 89c2b42bfe Reorginisation of line-drawing code. Also added a macro to benchmark line drawing logic. Addition of line_test_time to benchmark line drawing time (Do not work yet) hugova 2025-03-04 23:01:57 +01:00
  • 494e9dc5f9 A fix of line_up_inv such that X_pos < X_end like all other line_* implementations. hugova 2025-03-04 21:00:21 +01:00
  • 4d12f20a6e A Fix for D that gets the wrong initial value and the branch logic in line_* checked for the wrong value. A new proc, line.s that can chose whitch line_* to use A small test program in source.s Wrote a smal test program in source.s (all looks good exept line_up_inv) hugova 2025-03-03 22:08:00 +01:00
  • 1524c837ca A optimisation of line_up_inv.s by moving some logic out of loop hugova 2025-03-02 23:14:51 +01:00
  • f3712eca9f Move logic outside loop for performance reasons. Same as earlier commit but for line_down_inv.s, line_up.s Comment: Should do the same for line_up_inv.s hugova 2025-03-02 18:29:58 +01:00
  • ee69828ec7 Optimisation by moving logic out of loop for faster execution. This should be implemented on the other line_* files hugova 2025-03-02 18:05:20 +01:00
  • 0940d9f9f9 1. A fix for a bug where D gets the wrong initial value (2 bytes where flipped) 2. Implemented line drawing for the other 3 cases hugova 2025-03-02 16:51:55 +01:00
  • 4f396fd740 A fix to a bug, to make line_down draw lines with small slopes. I needed to use 16bit logic to ashive this. Also moved out dx*2, dy*2 calculation outside of loop for better performance. hugova 2025-03-01 23:57:15 +01:00
  • 9c86b570ed Will make the indenting better. Also it will properly use dubble ; for comment blocks hugova 2025-02-28 18:22:07 +01:00
  • 864b0e659b Add hugo code hugova 2025-02-27 22:04:43 +01:00
