You are required to program (in a high level language such as C, C++, Java) and implement a cache simulator which will have the following inputs and outputs:-
INPUTS OUTPUTS
Memory trace <=> smalltex.din (during code development microtex.din - see later) and each address is the current address, in RAM, of a Byte required by the CPU.
Cache size <=> size of cache in bytes
Block size <=> size of blocks in bytes
Degree of associativity <=> direct (1-way), 2-way, 4-way, 8-way, and fully associative
Replacement policy <=> Random and LRU are to be implemented.
Total miss rate = compulsory + capacity + conflict miss rates.
* The memory trace file (smalltex.din) is located at /home/csiii/csiiilib/arc/smalltex.din or /home/3rd/csiiilib/arc/smalltex.dinCopy this file to your arc directory where you will be running your assignment from.
Rules Of Data Normalisation Let us now summarise Normalisation with the help of various clean rules. The following are the necessary rules for the Normalisation process: 1.
Domain Constraint It shows that each attribute in a relation has to contain an atomic value only from the corresponding domains. The data types associated with commercial RDBMS
Define union compatibility? Explain why INTERSECTION of two relations cannot be performed if they are not union compatible? Two relations R(A1, A2,-------, An) and S(B1, B2,--
Fourth Normal Form (4NF) When attributes in a relation have multi-valued dependency, further Normalization to 4NF and 5NF are needed. Let us first find out what multi-valued d
Increased overheads on update : On the drawbacks side, it will need the system to ensure that all replicas of a relation are consistent. This shows that all the replicas of the rel
let us consider a table having 2200 records and the fixed size of the table to be considered as 25.then how many numbers of table is requredto perform horizontal fragmentation
WHY SHOULD NULL IN A RELATION BE AVOID AS possible?
CREATE TABLE prodtrans ( pno number (4) ptype char (1) CHECK (ptype in ('I','R','S')), qty number (5) FOREIGN KEY pno REFERENCES product (pno) ON DELETE CASCADE);
What is a view? How it is related to data independence? A view might be thought of as a virtual table, that is, a table that does not really exist in its own right but is inste
User error : This contains errors in the program (e.g., Logical errors) with errors made by online users of database. These types of errors can be avoided by applying some check
