The Register File is a 3 port memory, with 2 read ports and 1 write port. <br>
|
| 23 |
|
|
It has 32 locations, 8 bits each. <br>
|
| 24 |
|
|
Separate read and write ports for the upper three 16 bit words are provided. The upper three 16 bit words are the pointer registers X (at byte address 27:26), Y (29:28) and Z (31:30). <br>
|
