Consider a byte-addressable computer system with a 13-bit logical address, a total physical memory size of 4 KiB, and a page size of 64 Bytes. The system uses a segmented paging architecture where the logical address is divided into a Segment Number and a Segment Offset. The segment table provides a Base Address which is added to the Segment Offset to form a linear Address. This Linear Address is then translated via a single-level Page Table to a Physical Address.
Segment Table (Segment Base Addr, Binary):
| Idx | Segment Base Addr |
|---|---|
| 0 | 0000,0000,0000 |
| 1 | 0010,0000,0000 |
| 2 | 0001,1000,0000 |
| 3 | 0011,0000,0000 |
| 4 | 0000,1000,0000 |
| 5 | 0100,0000,0000 |
| 6 | 0101,0000,0000 |
| 7 | 0110,0000,0000 |
Page Table (Frame Number, Decimal)：
| Idx | Frame Number |
|---|---|
| 24 | 12 |
| 25 | 5 |
| 26 | 33 |
| 27 | 8 |
Given the Logical Address in hexadecimal format "16A4", and the tables above, what is the Segment Index derived from the logical address 16A4?
