A microprocessor scans the status of an output I/O device every 20 ms. This is accom- plished by means of a timer alerting the processor every 20 ms. The interface of the device includes two ports: one for status and one for data output. How long does it take to scan and service the device given a clocking rate of 8 MHz? Assume for sim- plicity that all pertinent instruction cycles take 12 clock cycles.
MIPS instructions classically take five steps: IF, ID, EX, MEM, WB. A certain MIPS pipeline has the following properties: - IF: 1 cycle - ID: 1 cycle - EX: 1 cycle for A type instructions, 2 cycles for B type instructions, 3 cycles for C type instructions. МЕМ: 1 суcle WB: 1 сycle EX stage of the pipeline has three separate datapaths, to accommodate for the various cycle counts. A-type instructions B-type instructions B-type instructions C-type C-type C-type instructions instructions instructions Run the following instruction sequences through this pipeline with and without forwarding (Assume full data hazard, meaning each instruction depends on data that was produced by the previous instruction, and assume no load/store instructions): a) AAAAAAAABBBBBBBBCCCCCCCC b) АВСАВСАВСАВСАВСАВСАВСАВС с) АСВАСВАСВАСВАСВАСВАСВАСВ

What would happen if an instruction was disobeyed, and why would that be the case? In the following scenarios, a TLB that is maintained by software is more efficient than one that is handled by hardware:
Computer Science Suppose, a control register of 8155 PPI has an address of 1Fh. If following instructions areexecuted in an 8085 microprocessor system, then derive the all the port functionalities (i.e.,including pins) of the 8155 PPI.MVI A, ABhOUT 1Fh
1. Assume we have a pipelined data path where the IF state takes 200ps, the ID stage takes 300ps, the EX stage takes 100ps, MEM takes 300ps, and WB takes 200ps. How long will an individual instruction take to complete in this pipelined datapath versus a single-cycle datapath with the same stages and timing?
Asap. Computer science
Question 2. Recall that the clock cycle time in a non-pipelined processor is determined by the instruction (considering all stages) that takes the longest time to execute as no instruction can take more than one cycle. In a pipelined datapath, the cycle time is determined by the individual stage that takes the longest time as each cycle will execute exactly one stage. Now assume the distribution of time required by independent stages are as follows: IF 250 ID 350 EX 150 MEM 300 WB 200 Now answer the following questions: a) What should be the clock cycle time for a non-pipelined and a pipelined processor? Provide justification for your answer. b) How long will it take to execute the lw instruction in a non-pipelined processor? Why? c) How long will it take to execute the lw instruction in a pipelined processor? Why?
