Consider 512Kx8bits dynamic RAM chips where the memory access time is 2/3 of the memory cycle time. These chips have an Address Bus, a bi-directional Data Bus, a Read/Write control line and a Chip Select line. (a) Draw the diagram of a memory organization that will contain 4 megabytes, will have a 32-bit bi-directional data bus and will yield one word (32-bits) every access time if words are read from consecutive memory locations (in bursts). Clearly show and explain the...

Consider a memory hierarchy using one of the three organization for main memory shown in a figure below. Assume that the cache block size is 32 words, That the width of organization b is 4 words, and that the number of banks in organization c is 2. If the main memory latency for a new access is 10 cycles, sending address time is 1 cycle and the transfer time is 1 cycle, What are the miss penalties for each of...

Memory Sizing NOTE: K (kilo) means 1024, not 1000. A byte (B) is 8 bits. A kilobyte (KB) is therefore 8 x 1024 = 8192 bits. a) A 32 KB (kilobytes) memory has a 16 bit wordsize. How many words total can be stored in this memory? _________words b) A 256 KB memory has a 32 bit wordsize. How many bits are required to address this memory? _________ bits c) A computer memory has a 128 bit wordsize. It is made up...

Question 10 (10 points) Consider a cache of 8 lines of 16 bytes each. Main memory is divided into blocks of 16 bytes each. That is, block 0 has bytes with addresses 0 through 15, and so on. Now consider a program that accesses memory in the following sequence of addresses: Loop three times: 10 through 20; 32 through 52. Once: 20 through 35. Suppose the cache is organized as direct mapped. Memory blocks 0, 8, 16 and so on...

20 pts] 2- Consider the internal structure of the pseudo-CPU discussed in class augmented with a single-port register file (i.e., only one register value can be read at a time) containing 32 8-bit registers (RO-R31) and a Stack Pointer (SP). Suppose the pseudo-CPU can be used to implement the AVR instruction ICALL (Indirect Call to Subroutine) with the format shown below: 10001 10101 00001 10011 ICALL pushes the return address onto the stack and jumps to the 16-bit target address...

Given: An 8-bit computer system with 4 MB of main memory. It has a 16K-words direct-mapped cache with a block size of 16 Bytes. Sought: Calculate the cache line number when Byte address2271len from main memory is mapped to cache. Consider that numbering of main memory blocks and cache lines starts from zero. Express your answer in hexadecimal. It is required to show ALL incremental steps of the solution.
