07740d19f3 add bigram compression to makeqstrdata
Compress common unicode bigrams by making code points in the range
0x80 - 0xbf (inclusive) represent them.  Then, they can be greedily
encoded and the substituted code points handled by the existing Huffman
compression.  Normally code points in the range 0x80-0xbf are not used
in Unicode, so we stake our own claim.  Using the more arguably correct
"Private Use Area" (PUA) would mean that for scripts that only use
code points under 256 we would use more memory for the "values" table.

bigram means "two letters", and is also sometimes called a "digram".
It's nothing to do with "big RAM".  For our purposes, a bigram represents
two successive unicode code points, so for instance in our build on
trinket m0 for english the most frequent are:
['t ', 'e ', 'in', 'd ', ...].

The bigrams are selected based on frequency in the corpus, but the
selection is not necessarily optimal, for these reasons I can think of:
 * Suppose the corpus was just "tea" repeated 100 times.  The
   top bigrams would be "te", and "ea".  However,
   overlap, "te" could never be used.  Thus, some bigrams might actually
   waste space
    * I _assume_ this has to be why e.g., bigram 0x86 "s " is more
      frequent than bigram 0x85 " a" in English for Trinket M0, because
      sequences like "can't add" would get the "t " digram and then
      be unable to use the " a" digram.

 * And generally, if a bigram is frequent then so are its constituents.
   Say that "i" and "n" both encode to just 5 or 6 bits, then the huffman
   code for "in" had better compress to 10 or fewer bits or it's a net
   loss!
    * I checked though!  "i" is 5 bits, "n" is 6 bits (lucky guess)
      but the bigram 0x83 also just 6 bits, so this one is a win of
      5 bits for every "it" minus overhead.  Yay, this round goes to team
      compression.
    * On the other hand, the least frequent bigram 0x9d " n" is 10 bits
      long and its constituent code points are 4+6 bits so there's no
      savings, but there is the cost of the table entry.
    * and somehow 0x9f 'an' is never used at all!

With or without accounting for overlaps, there is some optimum number
of bigrams.  Adding one more bigram uses at least 2 bytes (for the
entry in the bigram table; 4 bytes if code points >255 are in the
source text) and also needs a slot in the Huffman dictionary, so
adding bigrams beyond the optimim number makes compression worse again.

If it's an improvement, the fact that it's not guaranteed optimal
doesn't seem to matter too much.  It just leaves a little more fruit
for the next sweep to pick up.  Perhaps try adding the most frequent
bigram not yet present, until it doesn't improve compression overall.

Right now, de_DE is again the "fullest" build on trinket_m0.  (It's
reclaimed that spot from the ja translation somehow)  This change saves
104 bytes there, increasing free space about 6.8%.  In the larger
(but not critically full) pyportal build it saves 324 bytes.

The specific number of bigrams used (32) was chosen as it is the max
number that fit within the 0x80..0xbf range.  Larger tables would
require the use of 16 bit code points in the de_DE build, losing savings
overall.

(Side note: The most frequent letters in English have been said
to be: ETA OIN SHRDLU; but we have UAC EIL MOPRST in our corpus)

d5074220a8 atmel-samd: Add SAM E54 Xplained board
Few peripherals are actually tested.  However, USB, I2C and GPIO seem to work.

Most pins are silkscreened with the "PX00" style, so the board module
only includes the small number that are screened differently.

The default SPI, I2C, and UART are the ones on the EXT2 header.  This is
arbitrary, but the I2C on this connector is shared with the on-board I2C
devices and the PCC header, making it the most versatile.

Length was stored as a 16-bit number always.  Most translations have
a max length far less.  For example, US English translation lengths
always fit in just 8 bits.  probably all languages fit in 9 bits.

This also has the side effect of reducing the alignment of
compressed_string_t from 2 bytes to 1.

looked right.

- bump supervisor alloc count by 4 (we actually use 5)
 - move reconstruct to after gc heap is reset
 - destroy protomatter object entirely if not used by a FramebufferDisplay
 - ensure previous supervisor allocations are released
 - zero out pointers so GC can collect them

Refine iMX RT memory layout and add three boards
Introduces a way to place CircuitPython code and data into
tightly coupled memory (TCM) which is accessible by the CPU in a
single cycle. It also frees up room in the corresponding cache for
intermittent data. Loading from external flash is slow!

The data cache is also now enabled.

Adds support for the iMX RT 1021 chip. Adds three new boards:
* iMX RT 1020 EVK
* iMX RT 1060 EVK
* Teensy 4.0

Related to #2492, #2472 and #2477. Fixes #2475.

f4a5c17b5e supervisor: external_flash: don't call m_free when it's bad
It's extremely dubious that we have these handles that we think
are to GC'd memory at a time when the gc pool may not be initialized.
Hopefully, they WERE valid GC memory and are undisturbed by the teardown
of the interpreter that can lead to this state.

In this case, don't try to m_free them, the memory will become free when
the GC heap is reinitialized.

Closes: #2338 (together with previous commit)

translation: Compress as unicode, not bytes
2019-12-02 17:11:49 -08:00

e06a3bbceb translation: Compress as unicode, not bytes
By treating each unicode code-point as a single entity for huffman
compression, the overall compression rate can be somewhat improved
without changing the algorithm.  On the decompression side, when
compressed values above 127 are encountered, they need to be
converted from a 16-bit Unicode code point into a UTF-8 byte
sequence.

Doing this returns approximately 1.5kB of flash storage with the
zh_Latn_pinyin translation. (292 -> 1768 bytes remaining in my build
of trinket_m0)

Other "more ASCII" translations benefit less, and in fact
zh_Latn_pinyin is no longer the most constrained translation!
(de_DE 1156 -> 1384 bytes free in flash, I didn't check others
before pushing for CI)

English is slightly pessimized, 2840 -> 2788 bytes, probably mostly
because the "values" array was changed from uint8_t to uint16_t,
which is strictly not required for an all-ASCII translation.  This
could probably be avoided in this case, but as English is not the
most constrained translation it doesn't really matter.

Testing performed: built for feather nRF52840 express and trinket m0
in English and zh_Latn_pinyin; ran and verified the localized
messages such as
    Àn xià rènhé jiàn jìnrù REPL. Shǐyòng CTRL-D chóngxīn jiāzài.
