}Expand description
Table-scan slot.
Reads the two public entries 2*pair+1 and 2*pair+2 of table
digit (one table per digit, stored at table row row). The context’s
accumulator takes an entry exactly when the digit magnitude equals that
entry number. clear first resets the
accumulator to the identity; finish afterwards writes the accumulator,
negated when the digit is negative, into bank L.
A lookup is therefore a fixed sequence of scan steps whose rows depend only on the digit’s position, never on its value. A zero digit matches no entry and leaves the identity.
Fields§
§digit: u8Digit index, 0..DIGITS.
pair: u8Entry pair, 0..8 (radix 32) or 0..4 (radix 16).
row: u16Table row of this pair (table_row(digit) + pair).
clear: boolReset the accumulator before scanning.
finish: boolCommit the (conditionally negated) accumulator to bank L.
l_slot: u8Bank-L slot (0 or 1) the lookup commits to.
key: boolScan the per-key table (verification key) instead of the base-point
table. Key lookups read digits 64..64 + DIGITS.
