Summary

'11000100 11000000' translates to 'kata kana' according to the following table:

BitsConsonantVowel
00na
01ti
10su
11ke

As another example, '00 01 10 11 11 10 01 00' translates to 'nise kuta'.

Purpose

Many parts of the Logiweb system are prepared for entering text via a microphone or retrieving text via a loudspeaker. The Kana format is intended for representing bytes in the rare cases where bytes have to be 'pronounced'. Kana is not used in the present release of Logiweb but has been used previously and may re-appear later.

Origin

The Kana format is inspired by one of the Japanese alphabets.

Consonants

In the Kana format, the consonants n, t, s, and k represent the bit patterns 00, 01, 10, and 11, respectively.

Vowels

In the Kana format, the vowels a, i, u, and e represent the the bit patterns 00, 01, 10, and 11, respectively. Hence, each two-bit word can be represented either by a consonant or by a vowel

Syllables

In the Kana format, a four-bit word is represented by a consonant followed by a vowel where the consonant represents the first two bits and the vowel represents the last two bits. As an example, 'ka' represents 1100.

Bytes

In the Kana format, a byte is represented by two syllables where the first syllable represents the first four bits and the second syllable represents the last four bits. As an example, 'kana' represents 11000000.

Relation to mixed endian format

If a byte vector is written in mixed endian binary format and then translated to Kana, then the result will be referred to as 'mixed endian Kana'. If the byte vector is translated to little endian binary instead, then the result will be referred to as 'little endian Kana'. Example: Consider the mixed endian decimal byte vector 196 192. In mixed endian binary, it reads 11000100 11000000 which translates the 'kata kana' in mixed endian Kana.

Pronunciation

'10101001' becomes 'susi' in Kana. 'si' is pronounced 'shi' in Japanese, so 'susi' becomes 'sushi' in Japanese pronunciation, but the choice of pronunciation is left to individual users.
