Consider executing the following code on the pipelined datapath that we discussed in class. a). During the 5th cycle, which registers are being read and which register(s) will be written (using the register file)? add $t1, $t3, $t2 sub $t6, $t7, $t3 sub $t9, $t8, $t7 add $t8, $t5, $t9 add $t5, $t6, $t5 b). Explain what the forwarding unit is doing during the 5th cycle of execution. Which registers are being compared? List all pairs of registers that are compared during the 5th cycle for the forwarding unit. (First, you need to determine which instruction's values are in the EX/MEM, which instruction's values are in the MEM/WB register, and which instruction's values are read from the ID/EX register during the 5th cycle. Then check the conditions for forwarding.) c). Explain what the hazard detection unit is doing during the 5th cycle of execution. Which registers are being compared? List all pairs of registers that are compared during the 5th cycle for the hazard detection unit. (You need to determine which instruction's values are in the IF/ID and which instruction's values are in the ID/EX register during the 5th cycle. Then check the conditions for the hazard detection.)

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
