A pipeline (pipeline(a)) has initially seven segments as listed in Table1.1. It is compared to three other pipelines; Pipeline(b), Pipeline(c) and Pipeline(d). Find each pipeline clock cycle time in nano seconds, the total executing time for the indicated n tasks and the speed up ratio; (nk)/(n+k-1). Name Segment1 Segment2 Segment3 Segment4 Segment5 Segment6 Segment7
t t1 t2 t3 t4 t5 t6 t7
time in ns 135 115 155 225 95 75 40
tasks n 315
a- Pipeline(a) uses the original five segments as shown in Table
b- Pipeline(b) is the same as pipeline (a) with t4, split into 3 identical segments.
C- Pipeline(c) is the same as pipeline (a) with t2 and t3, combined into one segment
d- Pipeline(d) is the same as pipeline (a) with t4, split into 3 identical segments while t2, and t3 are combined into one segment.

Write a new lc-3 trap subroutine (i.e. a subroutine that will be invoked via the trap instruction) that will receive a numeric digit entered at the keyboard (i.e. an ascii character), echo it to the screen, and return in r0 the corresponding numeric value: so if the user types the digit '7', the character '7' will appear on the screen, but the value returned in r0 will be b0000 0000 0000 0111 (#7) you may not use any trap calls in your code - you must implement the "polling" code that interrogates the keyboard status and data registers. ; getnum_tsr ; a subroutine for obtaining a numeric value ; given ascii numeric digit input to keyboard. ; the numeric digit is echoed to the console (e.g. '7' = b0000 0000 0011 0111), ; but the value returned in r0 is the actual numeric value ; corresponding to the digit (e.g. b0000 0000 0000 0111 =

Carlos, an algebra teacher, is creating a series of powerpoint presentations to use during class lectures. after writing, formatting, and stylizing the first presentation, he would like to begin writing the next presentation. he plans to insert all-new content, but he wants to have the same formatting and style as in the first one. what would be the most efficient way for carlos to begin creating the new presentation? going under the file tab and opening the first presentation, deleting all content from each page, and adding new content going under the file tab and clicking on new in the left pane, then choosing new from existing going under the design tab and clicking on themes, then selecting the theme that was used for the first template going under the design tab and opening the template that was created for the first presentation
