Logiweb Help: Kana format

Home. Help index. Up.

Summary

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

Bits Consonant Vovel
00 n a
01 t i
10 s u
11 k e

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'.

Origin

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

Consonants

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

Vovels

In the Kana format, the vovels 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 vovel

Sylables

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

Bytes

In the Kana format, a byte is represented by two sylables where the first sylable represents the first four bits and the second sylable 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 Japaneese, so 'susi' becomes 'sushi' in Japaneese pronunciation. Personally, I pronounce Kana in Danish and leave the choice of pronunciation to individual users (if any:-).
