Class Notes of CSCI 370 Computer Architecture (Spring 2026)
===========================================================

word  b, c, a;          // 1 word = 4 bytes
lw  $t1, 8($t6)         // $t1 = a

relocatable address
$t6 = 1008 (1000 + 8)  // base address = 1000
$t6 = 2008 (2000 + 8)  // base address = 2000

4th generation:
SQL: FIND ALL RECORDS WHERE NAME IS "SMITH"

3rd generation:
for ( i = 0; i < 1000; i++ ) {
   if ( name[i] == "SMITH" )
     print record[i]
}
 
CPU (with +, but no x)
1 + 2 = 3

Microarchitecture (without x)
2 x 3 = 6 = 2 + 2 + 2 (microcode or firmware)
