Guide on Searching Data Cache (Virtual Memory) - Nir's Reception Hour
|
Dear students, Due to some confusions in today's reception hour, attached a short guide on how to know which entries are inside the data cache - regarding Winter 16-17 Moed A question 1: Each table is aligned, and each cache block size is 32b = 2^5b, so |cache offset| = 5. First, we access B (for PML3), A (for PML2), 9 (for PTE), and fill the PMH caches and data cache accordingly. Second, we access B (for PML3), B (for PML2), A (for PTE). Therefore, we have PML3 Cache HIT, and PML2 Cache MISS (make sure you understand why). Now we will check if B (in PML2) was previously inserted to the Data cache. Here is a way to check it: Each PTE is 4=2^2 bytes, so we will first convert the A entry to binary, attaching 2 bits for the PTE size. A = ... 1010 00 So we will insert A to the cache line, together with 7 additional PTEs (32 bytes block, 4 bytes PTE): 8 (... 1000 00), 9 (... 1001 00), B (... 1011 00), C (... 1100 00), D (... 1101 00), E(... 1110 00), F(... 1111 00). The five least significant bits are the offset, so if the rest of the bits are equal, those PTEs are inserted together. Therefore, we receive HIT for entry B in the PML2 table in the second access. If you have additional question you are welcomed to ask. |

Clarification about Nir's tutorial today - ROB
|
Dear students, I was asked in the tutorial about the following situation: What if the ROB is limited (assume size = 4), and the first & second entries were commited before the third and the fourth (which are also allocated). In this case - we fill the first and second entries with new commands - and now it seems like the retirement won't be in-order. The solution is the following: During the process we hold two special registers: 1) commit register - points to the next instruction to be commited. 2) issue register - points to the next entry to be filled. Both registers will move cyclic over the ROB. Before we insert the two new commands inside the first two entries in the rob, the commit register will point to the third instruction (next instruction to be commited), and the issue register will point to the first instruction (next entry to be filled). In this case, it is guaranteed that the first and second entries will be commited only after the third and the fourth will. (After the third & fourth will be commited, we will move the commit register to the beginning of the ROB) i.e, you can consider the ROB as an hardware queue. If you have any more questions, please contact me by mail or schedule with me. Nir |
