28 | Any given LDC collects data from a number of D-RORC cards connected to this same LDC by separate DDLs. This data is stored in corresponding number | |
29 | of DDL buffers. | |
30 | ||
31 | Each DDL buffer corresponds to a single D-RORC. The data this buffer contains are hardware generated by D-RORC. The buffer starts with common header | |
32 | which size and structure is standartized and mandatory for all detectors. | |
33 | The header contains among other words, so called Equipment ID word. This unique value for each D-RORC is calculated as detector ID << 8 + DDL index. | |
34 | For HMPID the detector ID is 6 (reffered in the code as kRichRawId) while DDL indexes are from 0 to 13. | |
35 | ||
36 | Common header might be followed by the private one although HMPID has no any private header, just uses the common one. | |
37 | ||
38 | Single HMPID D-RORC serves one half of a chamber i.e. 3 photocathodes even LDC for left part( PCs 0-2-4) and odd LDC for right part(1-3-5) | |
39 | as it's seen from electronics side. | |
40 | ||
41 | So the LDC -chamber-ddl map is: | |
42 | DDL index 0 -> ch 1 left -> DDL ID 0x600 DDL index 1 -> ch 1 right -> DDL ID 0x601 | |
43 | DDL index 2 -> ch 2 left -> DDL ID 0x602 DDL index 3 -> ch 2 right -> DDL ID 0x603 | |
44 | DDL index 4 -> ch 3 left -> DDL ID 0x604 DDL index 5 -> ch 3 right -> DDL ID 0x605 | |
45 | DDL index 6 -> ch 4 left -> DDL ID 0x606 DDL index 7 -> ch 4 right -> DDL ID 0x607 | |
46 | DDL index 8 -> ch 5 left -> DDL ID 0x608 DDL index 9 -> ch 5 right -> DDL ID 0x609 | |
47 | DDL index 10 -> ch 6 left -> DDL ID 0x60a DDL index 11 -> ch 6 right -> DDL ID 0x60b | |
48 | DDL index 12 -> ch 7 left -> DDL ID 0x60c DDL index 13 -> ch 7 right -> DDL ID 0x60d | |

50 | HMPID FEE as seen by single D-RORC is composed from a number of DILOGIC chips organized in vertical stack of rows. | |
51 | Each DILOGIC chip serves 48 channels for the 8x6 pads (reffered in the code as kDilX,kDilY). Channels counted from 0 to 47. | |
52 | ||
53 | The mapping inside DILOGIC chip has the following structure (see from electronics side): | |
54 | ||
55 | 5 04 10 16 22 28 34 40 46 | |
56 | 4 02 08 14 20 26 32 38 44 | |
57 | 3 00 06 12 18 24 30 36 42 | |
58 | 2 01 07 13 19 25 31 37 43 | |
59 | 1 03 09 15 21 27 33 39 45 | |
60 | 0 05 11 17 23 29 35 41 47 | |
61 | ||
62 | 0 1 2 3 4 5 6 7 padx | |
63 | ||
64 | 10 DILOGIC chips composes so called "row" in horizontal direction (reffered in the code as kNdil), so the row is 80x6 pads structure. | |
65 | DILOGIC chips in the row are counted from right to left as seen from electronics side, from 1 to 10. | |
66 | 24 rows are piled up forming the whole FEE served by single D-RORC, so one DDL sees 80x144 pads separated in 3 photocathodes. | |
67 | Rows are counted from 1 to 24 from top to bottom for right half of the chamber (PCs 1-3-5) as seen from electronics side, meaning even LDC number | |
68 | and from bottom to top for left half of the chamber (PCs 0-2-4) as seen from electronics side, meaning odd LDC number. | |
69 | ||
70 | HMPID raw word is 32 bits with the structure: | |
71 | 00000 rrrrr dddd aaaaaa qqqqqqqqqqqq | |
72 | 5 bits zero 5 bits row number (1..24) 4 bits DILOGIC chip number (1..10) 6 bits DILOGIC address (0..47) 12 bits QDC value (0..4095) | |
