(12) Direct data cache of 4 bytes by 2 lines is initially empty. Memory starts at address 0 to the left. The memory is initialized as follows : 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 ------------------------------------------------------------------------------------- | T | h | i | r | d | - | t | e | s | t | - | C | S | C | I | - | 4 | 6 | 3 | - | - | ------------------------------------------------------------------------------------- Cells are 8 bits and addresses in Hex. Program below performs the specified memory access. Show cache after each memory read. Indicate hit or miss on the appropiate line and CIRCLE specific byte in cache being read. A = accumulator m(i) is memory being read where i is specific address. A = m(00) Tag 0 1 2 3 H/M ------------------------------ | | | | | | | line 1 ------------------------------ | | | | | | | line 0 ------------------------------ A = m(0A) Tag 0 1 2 3 H/M ------------------------------ | | | | | | | line 1 ------------------------------ | | | | | | | line 0 ------------------------------ A = m(01) Tag 0 1 2 3 H/M ------------------------------ | | | | | | | line 1 ------------------------------ | | | | | | | line 0 ------------------------------ A = m(0B) Tag 0 1 2 3 H/M ------------------------------ | | | | | | | line 1 ------------------------------ | | | | | | | line 0 ------------------------------ A = m(02) Tag 0 1 2 3 H/M ------------------------------ | | | | | | | line 1 ------------------------------ | | | | | | | line 0 ------------------------------ A = m(0C) Tag 0 1 2 3 H/M ------------------------------ | | | | | | | line 1 ------------------------------ | | | | | | | line 0 ------------------------------
