Upkr is a simple general purpose lz packer designed to be used in the [MicroW8](https://github.com/exoticorn/microw8) platform.
|
||||
The compressed format is losely based on [Shrinkler](https://github.com/askeksa/Shrinkler) with the main difference being that
|
||||
Upkr doesn't differentiate between literals at odd or even addresses (by default) and that I went with rANS/rABS instead of a range coder.
|
||||
Upkr doesn't differnetiate between literals at odd or even addresses and that I went with rANS/rABS instead of a range coder.
|
||||
|
||||
Compression rate is on par with Shrinkler.
|
||||
|
||||
The differences compare to Shrinkler also makes it interesting on 8bit platforms. The z80 unpacker included in the release
|
||||
is both about twice as fast and smaller than the Shrinkler unpacker.
|
||||
At this point, Upkr should still be considered unstable - the compressed format is not very likely to change but I still want
|
||||
to keep that option open a little longer.
|
||||
|
||||
## Inspirations:
|
||||
|
||||
* Ferris' blog about his [C64 intro packer](https://yupferris.github.io/blog/2020/08/31/c64-4k-intro-packer-deep-dive.html)
|
||||
* [Shrinkler](https://github.com/askeksa/Shrinkler)
|
||||
* Ryg's [sample rANS implementation](https://github.com/rygorous/ryg_rans)
|
||||
|
||||
## Unpackers
|
||||
|
||||
The release includes a reference c unpacker, as well as some optimized asm unpackers (arm and riscv). The unpckers in
|
||||
c_unpacker and asm_unpackers unpack the default upkr compressed format. The z80_unpacker
|
||||
is based on some variations to the compressed format. (Use `upkr --z80` to select those variations.)
|
||||
The 16 bit dos unpacker also uses some variations. (`upkr --x86`)
|
||||
|
||||
## Usage
|
||||
|
||||
```
|
||||
upkr [-l level(0-9)] [config options] <infile> [<outfile>]
|
||||
upkr -u [config options] <infile> [<outfile>]
|
||||
upkr --heatmap [config options] <infile> [<outfile>]
|
||||
upkr --margin [config options] <infile>
|
||||
|
||||
-l, --level N compression level 0-9
|
||||
-0, ..., -9 short form for setting compression level
|
||||
-u, --unpack unpack infile
|
||||
--heatmap calculate heatmap from compressed file
|
||||
--margin calculate margin for overlapped unpacking of a packed file
|
||||
|
||||
Config presets for specific unpackers:
|
||||
--z80 --big-endian-bitstream --invert-bit-encoding --simplified-prob-update -9
|
||||
--x86 --bitstream --invert-is-match-bit --invert-continue-value-bit --invert-new-offset-bit
|
||||
--x86b --bitstream --invert-continue-value-bit --no-repeated-offsets -9
|
||||
|
||||
Config options (need to match when packing/unpacking):
|
||||
-b, --bitstream bitstream mode
|
||||
-p, --parity N use N (2/4) parity contexts
|
||||
-r, --reverse reverse input & output
|
||||
|
||||
Config options to tailor output to specific optimized unpackers:
|
||||
--invert-is-match-bit
|
||||
--invert-new-offset-bit
|
||||
--invert-continue-value-bit
|
||||
--invert-bit-encoding
|
||||
--simplified-prob-update
|
||||
--big-endian-bitstream (implies --bitstream)
|
||||
--no-repeated-offsets
|
||||
--eof-in-length
|
||||
--max-offset N
|
||||
--max-length N
|
||||
```
|
||||
|
||||
## Heatmap
|
||||
|
||||
By default, the `--heatmap` flag writes out the heatmap data as a binary file. The heatmap file is
|
||||
the same size as the unpacked data. Each byte can be interpreted like this:
|
||||
|
||||
```
|
||||
is_literal = byte & 1; // whether the byte was encoded as a literal (as opposed to a match)
|
||||
size_in_bits = 2.0 ** (((byte >> 1) - 64) / 8.0); // the size this byte takes up in the compressed data
|
||||
```

maximum compatibility, relocates unpacked code to normal start address

saves some bytes by not relocating, unpacked code needs to be assembled to

start at 0x3FFE

unpack_x86_16_DOS_no_repeated_offset.asm:

removes support for repeated offsets, potentially at the cost of some compression ratio.

most likely only a win in very narrow circumstances around the 1kb mark

; This is the 16-bit DOS x86 decompression stub for upkr, which is designed for
|
||||
; maximum compatibility: it relocates the compressed data so it can be
|
||||
; decompressed starting at the normal .COM starting address. In other words,
|
||||
; many of the already existing .COM files should be compressable using this
|
||||
; stub.
|
||||
;
|
||||
; How to use:
|
||||
; 1) Pack your intro using upkr into data.bin with the --x86 command line
|
||||
; argument:
|
||||
;
|
||||
; $ upkr --x86 intro.com data.bin
|
||||
;
|
||||
; 2) Compile this .asm file using nasm (or any compatible assembler):
|
||||
;
|
||||
; $ nasm unpack_x86_16_DOS.asm -fbin -o intropck.com
|
||||
;
|
||||
; The packed size of the intro+stub is limited by max_len (see below) bytes.
|
||||
;
|
||||
; In specific cases, the unpacker stub can be further optimized to save a byte
|
||||
; or two:
|
||||
; 1) You can remove CLC before RET, if you don't mind carry being set upon
|
||||
; program entry
|
||||
; 2) You can also move PUSHA before PUSH SI and put POPA as the first
|
||||
; operation of the compressed code.
