cache simulator

CDA3101 - Spring 2002 Chapter 7 Programming Assignment Data Cache Simulator Due at the beginning of class April 10, 2002 Responsible TA: T. Thomas Your assignment is to write a program that simulates the behavior of a data cache. The program will read a trace of references from standard input and produce statistics about the trace to standard output. The grading process will include applying your simulator to multiple reference traces. The cache simulator should first determine the configuration of the data cache. This is accomplished by reading the configuration information on the first three lines of standard input. These lines specify the number of cache sets, the number of elements of each set (associativity level), and the size of a cache line in bytes. The format of the configuration is shown below (note that the values specified after the colon on each line are the portion that can change). You may assume that the number of sets does not exceed 8192 and the associativity level does not exceed 8. You may also assume that the format and numbers specified in these three lines are valid. Number of sets: 8 Set size: 1 Line size: 4 The trace of references follow the configuration information and has the following format: ::where can be the characters: R - indicates a read access W - indicates a write access is the size of the reference in bytes (1,2,4, or 8), and is the starting byte address of the reference expressed as a hexadecimal number. You may assume that lines in the trace file conform to the format, e.g., you do not have to check for lines that have an incorrect number of fields. The example trace of references below, contains the addresses that correspond to the example references described on page 547 and 548 of your text. Note the addresses here are hexadecimal byte addresses rather than the decimal word addresses used in the text. R:4:58 R:4:68 R:4:58 R:4:68 R:4:40 R:4:c R:4:40 R:4:48 A file containing the cache configuration information and the trace data is available at "[login to view URL]˜gallivan/[login to view URL]". -1- You can read the , , and into a character and two integers, respectively, using formatted I/O with the following type of scanf statement. scanf("%c:%d:%x", &accesstypevariable, &sizevariable, &hexaddressvariable); Your cache simulator should use an LRU replacement algorithm.
