Use the Direct-Mapped Cache Simulator:
https://www3.ntu.edu.sg/home/smitha/ParaCache/Paracache/dmc.html
- Assume we have a 64Kbyte of RAM and direct-mapped byte-addressed cache with capacity 256 Bytes and block size of 32 Bytes. Use Write Policies Write Back & Write On Allocate.
Answer the following questions:
How many Memory Blocks in RAM?
How many Memory Blocks in the Cache?
How many bits is the Cache TAG?
How many bits is the Cache Index?
How many bits is the Cache Offset?
Manually enter the provided instructions into the simulator to fill in the following tables:
| L/S | Address (Hex) | Tag (Binary) | Index (Binary) | Offset (Binary) | RAM Block (Hex) |
| Store | 0x8132 | ||||
| Store | 0xcf15 | ||||

whose numerator and denominator are. be equal to 0 (Q=0). In other words, a rational algebraic expression is an expression ACTIVITY 2 Identify each expression if it is a rational algebraic expression or not. Write RAE it's a rational algebraic expression, if not, write NRAE. 11. 5. m 10. 12. d+45 3x+3 X-9x-10 ACTIVITY 3 Evaluate the rational algebraic expressions. Use another sheet of paper if necessary. 1. 3x 510 :x=3 2. m+m-2 m-1 m=-1 3. p-3p+2p;p=-2 p-5p+6
