The class I'm taking is assembly programming. I am completely stuck .Thank you so much for your help! Any help is greatly appreciated.
Suppose the logic blocks used to implement the processor as discussed in class have the following delays: Instr/Data Memory Access Register File Decode+Read Mux ALU Adder (outside ALU) Single gate delay Register read Register Write Sign Extend 250ps 150ps 25ps 200ps 150ps 5ps 30ps 20ps 50 a) How much time would you expect to take to execute an R-type instruction based on the details studied in class? b) How much time would you expect to take to execute an lw instruction based on the details studied in class? (0.4 c) Based on these two questions, is it possible to guess what would the (minimum) clock cycle time be of such a processor if the instructions are executed in one cycle? If yes, indicate it. If it is not, state the reason why not.

H.W.: Consider a hypothetical machine with two steps instruction cycle: fetch cycle and execute cycle. The characteristics of the machine is given in Figure 8 with the following explanation: The processor contains a single data register, called an accumulator (AC). • Both instructions and data are 8 bits long. • The memory is organized using 8-bit words. • The instruction format provides 2 bits for the opcode, and up to 26 = 64 words of memory can be directly addressed.

Suppose we have two implementations of the same instruction set architecture. Computer A has a clock cycle time of 210 ps and a CPI of 2.2 for some programs, and computer B has a clock cycle time of 460 ps and a CPI of 1.3 for the same program. Which computer is faster for this program and by how much? Please and thank you
In this case, every instruction gets its own data in a way that is completely separate from how the data of other instructions is obtained. We utilize: A Multiple Data/Instruction B Multiple Data/Instruction C Singular Data Single Inst D Singe Inst Multiple
Suppose that we are developing a new version of the AMD Barcelona proces- sor with a 4 GHz clock rate. We have added some additional instructions to the instruction set in such a way that the number of instructions has been reduced by 15% from the values shown for each benchmark in Exercise 1.12. The execution times obtained are shown in the following table. a. Name Execution Time (seconds) Reference Time (seconds) bzip2 700 9650 SPECratio 13.7 1.13.2 [10] In general, these CPI values are larger than those obtained in previous exercises for the same benchmarks. This is due mainly to the clock rate used in both cases, 3 GHz and 4 GHz. Determine whether the increase in the CPI is similar to that of the clock rate. If they are dissimilar, why?
