Simulator plugins are not (yet) version-checked. API version numbering restarted, as this is an all-new system. Uses the target ID from configure, so don't change that too often. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8349 a1c6a512-1295-4272-9138-f99709370657

* Coldfire: New timer handling on CPU frequency change, adjusting the ↵Jens Arnold2005-10-03
| | | | | | prescaler on the fly, for both tick and user timer. Precondition is that the higher frequencies are integer multiples of the base: now NORMAL is 45 MHz and MAX is 124 MHz. Removes the need for applications with longer timer periods (>= 10 ms) to boost the CPU all the time, e.g. the grayscale lib. Timer counts are now always based on the base frequency (CPU_FREQ). * Adjusted the RAM refresh timers to the new frequencies (all frequencies for H100) * All: Fixed the tick timer count being off by one. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7576 a1c6a512-1295-4272-9138-f99709370657
* H1x0: Changed lcd_blit() and the grayscale library to use the same internal ↵Jens Arnold2005-09-30

While the slowdown of the ISR is minimal (the intermediate buffers are in IRAM), the planar grayscale buffer takes only half the space for a given depth, and gray_update[_rect]() and unbuffered drawing/scrolling are faster because less data needs to be moved. It should also make porting of video.rock somewhat easier. * Archos recorders, Ondios: Some slight optimisations of the grayscale library. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7571 a1c6a512-1295-4272-9138-f99709370657

* Heavily improved mandelbrot plugin: (1) Calculation now uses 64bit fixed ↵Jens Arnold2005-07-30
| | | | | | point arithmetics to allow zooming in way further before the precision barrier will hit. Added asm-optimised 64bit multiplication routine for SH1; more than twice as fast as what gcc produces. (2) Precision is dynamically selected based on the zoom level, low zoom factors still use 32bit for speed. (3) Maximum number of iterations is adapted to the zoom level. You can still increase / decrease it while staying at a zoom level. (4) Panning only recalculates the scrolled-in part of the screen -> way faster panning. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7258 a1c6a512-1295-4272-9138-f99709370657

* Complete rework of the grayscale library: (1) Implemented the new rockbox ↵Jens Arnold2005-07-25
| | | | | | graphics api. (2) Added buffered mode, and implemented most drawing functions for buffered mode only. Buffered mode will ease implementation of animated graphics. Some functions are additionally provided as unbuffered versions (drawing grayscale bitmaps, scrolling) since unbuffered mode is better suited for non-animated graphics (JPEG viewer, mandelbrot) and saves some RAM, which is important on Archos. (3) Put all functions in a couple of source files, no more one-function-per-files. This became possible since sectioned compilation for the plugin library and appropriate linking for the pluginswas introduced, otherwise the binaries would be bloated by unused functions. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7241 a1c6a512-1295-4272-9138-f99709370657
