CS 2734 Computer Organization II

• Informal Quiz 4: hand assembly of MAC-1.

• Discussion of C constructs needed for Laboratory 6.
  • Use strtok to parse the tokens from the line:

           char *strtok(char *s, const char *ct);
    

    The function strtok searches s for tokens deliminted by characters from ct.

  • Use fgets to read in a line from the source:

          char *fgets(char *s, int n, FILE *stream); 
    

    The fgets function reads at most n - 1 characters from the file stream into the array s. It reads only up through a newline character and terminates the result by a zero byte. The function returns s if successful or NULL if there was an end of file.

• Implementation of the symbol table using hashing.

• Macros versus procedure calls.

• Start discussion of linking and loading.

SKILL: You should understand how symbol tables are implemented.
