What is the reachable memory space for a computer using a 12-bit address mechanism? What is the maximum amount of memory bits that this computer can have assuming memory cells are 4 bits in size?
Assume that a personal computer must get FIVE pieces of data from itsmemory for every operation (one piece of data indicates Which instructionto perform: the other is the intormation which is operated on). If thecomputer is the size of a typical PC. how long does it take to get these pieceof data? From this, what is the maximum rate at which the PC can executeuctions?
Consider a Computer which has a memory which is capable of storing 4096 K words and each word in memory can be of size 32 bits. The computer supports a total of 6 addressingmodes, and it has 60 computer registers. The computer supports instructions, where each instruction consists of following fields: Mode Operation code Register Register Memory AddressGiven that each instruction will be stored in one memory word, discuss with a suitable diagram the format of instruction by specifying number of bits for each field of instruction. Discuss each field of instruction.
Suppose the RAM for a certain computer has 256M words, where each word is 16 bits long. If this RAM is byte addressable, how many bits must an address contain?
Unlike a byte that is always 8 bits, word size can vary from machine to machine. Let's say we have a 16-bit system (word size is 2 bytes) and a memory unit that has 10 address lines. Because there are 10 address bits, we can have 210 unique addresses, hence 1024 addresses. If we are working with something word-addressable, that means each word has a unique address, and we canstore 1024 words. The memory size is 1 kiloword, or equivalently, 2kilobytes because each word is 2 bytes long. The address of the first word is 0, the second word is 1, the third word is 2, and the last word is 1023.Now, with 4 address lines and a word size of 4 bits, what is the address of the last word?
Suppose the RAM for a certain computer has 256M words, where each word is 16 bits long.If this RAM is word addressable, how many bits must an address contain?
This was previously asked and answered, but I need it in a format similar to what is depicted in the image attached, but with 6 stage instead of 4 stage. R1 = X + 1Y = R1 + R2R1 = R2 + X Complete the following: Lay the instructions out as they would be fed through a 6-stage CPU pipeline not accounting for any hazards. S1: Fetch instruction, S2: Decode opcode, S3: Calc effective address of operands, S4: Fetch operands, S5: Execute instruction, S6: Store result Identify any hazards present "Fix" the pipeline process to remove the hazards

Consider a hypothetical microprocessor generating a 16-bit address (for example, assume that the program counter and the address registers are 16-bits wide) and having a 16-bit data bus. What is the maximum memory address space that the processor can access directly if it is connected to a “16-bit memory”? What is the maximum memory address space that the processor can access directly if it connected to an “8-bit memory”? What architectural features will allow this microprocessor to access a separate I/O spece? If an input and an output instruction can specify an 8-bit I/O port number, how many 8-bit I/O ports can the microprocessor support? How many 16-bit I/O ports can the microprocessor support? Are the values in d and e the same?
