From 1989 to 1998, the maximum clock speed of Intel's processors increased 350 percent. New micron production processes and copper-based circuits continue the acceleration at an even faster rate. Much faster - and cheaper – processors are anticipated. In the midst of this progress, there are whispers of "planned obsolescence" among some naysayers. Faster processor speed and new software that demands it, they argue, will make a PC bought today obsolete in two years. Besides, they continue, is the increased speed really necessary? What do you think? Is greater processor speed a benefit for manufacturers and consumers alike, or is it a boon for builders and a burden for buyers? Why?​

The instruction ishl (shift left integer) exists in jvm but not in ijvm. it uses the top two values on the stack, replacing the two with a single value, the result. the sec- ond-from-top word of the stack is the operand to be shifted. its content is shifted left by a value between 0 and 31, inclusive, depending on the value of the 5 least signifi- cant bits of the top word on the stack (the other 27 bits of the top word are ignored). zeros are shifted in from the right for as many bits as the shift count. the opcode for ishl is 120 (0x78).a. what is the arithmetic operation equivalent to shifting left with a count of 2? b. extend the microcode to include this instruction as a part of ijv.
