Answer 1

Answer #1

--> Instruction fetches can be done in blocks, because most of the time instructions will executed sequentially.

This will help in saving time for next instruction reads.

--> But In the case of the data it is not the true. So, we will only bring data that is asked for.

--> That's why there is a split in L1 cache as data and instruction caches.

Base machine has a 2.4GHz clock rate. There is L1 and L2 cache. L1 cache is 256K, direct mapped write through. 90% (read) hit rate without penalty, miss penalty is 4 cycles. (cost of reading L2) All writes take 1 cycle. L2 cache is 2MB, 4 way set associative write back. 95% hit rate, 60 cycle miss penalty (cost of reading memory). 30% of all instructions are reads, 10% writes. All instructions take 1 cycle - except reads which take...

GG Products, Inc., prepares tips and stems from a joint process using asparagus. It produced 300,000 units of tips having a sales value at the split-off point of $66,000. It produced 300,000 units of stems having a sales value at split-off of $44,000. Using the net realizable value method, the portion of the total joint product costs allocated to tips was $63,000. Required:Compute the total joint product costs before allocation. (Do not round intermediate calculations.)
