COP 4600 Univeristy of Florida Computer Science Memory Simulator Question

You are provided with memory traces to use with your simulator. Each trace is a real recording

of a running program, taken from the SPEC benchmarks. Real traces are enormously big: billions

and billions of memory accesses. However, a relatively small trace will be more than enough to

keep you busy. Each trace only consists of one million memory accesses taken from the

beginning of each program. The traces are the following (linked from the Canvas project):

1. bzip.trace

2. sixpack.trace

Each trace is a series of lines, each listing a hexadecimal memory address followed by R or W to

indicate a read or a write. For example:

0041f7a0 R

13f5e2c0 R

05e78900 R

004758a0 R

31348900 W

Note, to scan in one memory access in this format, you can use fscanf() as in the following:

unsigned addr;

char rw;

…

fscanf(file,”%x %c”,&addr,&rw);
