13 | // AliL3DataHandler | |
14 | // | |
15 | // HLT Binary file handler. | |
16 | // | |
17 | // This class have more or less the same functionality as AliL3MemHandler, | |
18 | // except that it handles 8 bit ADC-values. Reading and writing is done in the same way | |
19 | // as illustrated in example 1) and 2) in AliL3MemHandler. | |
20 | // | |
21 | // For converting 10 bit data files to 8 bit data files, do: | |
22 | // | |
23 | // AliL3MemHandler *file = new AliL3DataHandler(); | |
24 | // file->SetBinaryInput(inputfile); //10 bit data file | |
25 | // file->SetBinaryOutput(outputfile); //8 bit data file | |
26 | // file->Convert10to8Bit(); | |
27 | // file->CloseBinaryInput(); | |
28 | // file->CloseBinaryOutput(); | |
29 | // delete file; | |
30 | // | |
31 | // Compress data format | |
32 | // -------------------- | |
33 | // | |
34 | // The data is RLE encoded, using _8_bit representation of the ADC-values. | |
35 | // Conversion is done in the class AliTransBit. | |
36 | // | |
37 | // In the beginning of every row, the row number if written and the number of pads | |
38 | // containing data on that row. For every pad with data the pad number is written, | |
39 | // and then comes the ADC-values on that pad. When a serie of zeros occure, a zero | |
40 | // is written followed by the number of zeros. If the number of zeros is more than | |
41 | // 255 (8 bit), another 8 bit word is written for the remaining. At the end of one | |
42 | // pad, 2 zeros are written. | |
43 | // | |
44 | // Example: | |
45 | // | |
46 | // ROW PAD 0 NZEROS ADC ADC ADC ADC 0 NZEROS ADC ADC 0 0 | |
47 | // | |
48 | // Everything is written using 8 bit; | |
49 | // (ROW < 176, PAD < 200, ADC < 255, if(NZEROS > 255) write 2 words;) | |
