 ====== Assignment 2 ======
+ Write a cache simulator (CacheSim) to simulate a cache. The simulator should be able to simulate up to 64KB cache. The simulator should run as CacheSim size in KB [flags], the flags are shown below
+The memory is byte addressable with word access, words are 4 bytes
+  - -a followed by the associativity (from 1 to 8), default is 1
+  - -b block size in bytes, default is 32
+  - -r followed bu U (unified) or S (split), default is unified
+  - -f trace memory file name
+For example
+CachSim 32 -a 4 -b 16 -r U
+The input t the simulator is a memory trace file. The file consists of lines, each line contains an integer i, followed by a 32-bit hex number.
+The hex number is the memory address, the integer i is
+  * 0  → data load
+  * 1  → data store
+  * 2  → instruction load
+I will post shortly test trace files to check your code
+**Due date** <del>Friday Oct 14</del> **//MONDAY Oct 17//**
+Here is the correct {{:assignments:trace.txt|trace file}}  for a direct mapped  16KB cache with 32 B cache block the number of misses is 25.
+for 2-way set associative the misses are **//also 25//**
+you can submit it to a2
+submit 4201 a2 yourfile
+a bigger trace file is here {{:assignments:tex.txt|}}
