Module tables

Lookup-tables used by Engine:s.

All tables are global and each is initialized at most once.

Tables

Table	Size	Used in encoding	Used in decoding	By engines
Exp	128 kiB	yes	yes	all
Log	128 kiB	yes	yes	all
LogWalsh	128 kiB	-	yes	all
Mul16	8 MiB	yes	yes	NoSimd
Skew	128 kiB	yes	yes	all

Functions

initialize_exp_log

Initializes and returns Exp and Log tables.

initialize_log_walsh

Initializes and returns LogWalsh table.

initialize_mul16

Initializes and returns Mul16 table.

initialize_skew

Initializes and returns Skew table.

mul

Calculates x * log_m using Exp and Log tables.

Type Aliases

Exp

Used by Naive engine for multiplications and by all Engine:s to initialize other tables.

Log

Used by Naive engine for multiplications and by all Engine:s to initialize other tables.

LogWalsh

Used by all Engine:s in Engine::eval_poly.

Mul16

Used by NoSimd engine for multiplications.

Skew

Used by all Engine:s for FFT and IFFT.
