Choose all the following characteristics that are applicable RISC processor. a. Variable-length instructions b. Fixed-length instructions c. Many instructions (typically, hundreds) d. Strives for a minimum instruction set e. Each instruction perfoms a basic computation f Each instruction can perfom an arbitraily complex computation (.4. In the integer multiplication, if we ignore the sign bits, what is the length of the product of a n-bit multiplicand and an m-bit multiplier a. n b. m c. 2n d. 2m e. m f n m g. None of the above (1.5). A conventional programming language, such as Java or C, is classified as high level language (HLL). Corresponding to HILL there are Low-level languages (LLL). The most widely used Low-level language is known as assembly language. Choose all the following characteristics that are applicable to assembly language. a. Many-to-one translation: each statement corresponds to many machine instruction. b. One-to-one translation: each statement corresponds to one machine instruction. c. Hardware Dependence d. Hardware Independence (1.60. Assume that one processor has 10 pipeline stages, and it is perfectly pipelined, how much speed up will it achieve compared to nonpipelined processor. (.7).

These events are called hazards. Please name what are the three different types of hazards?

Explanation / Answer

1- c

Growth rate means the increased rate of the device from beginning to current. It should not be confused with largest amount produced.

Hence the embedded computers have grown at a rate of more than 6-7 times in previous years.
