For the single-cycle CPU, the minimum clock period is simply the sum of the delays through all five sub-components (not stages, as there is only one stage). The assumption that the pipelining overhead is zero means that the minimum clock period of the pipeline CPU is simply the longest individual stage delay.
What is a clock period?
The clock period or cycle time, Tc, is the time between rising edges of a repetitive clock signal. Its reciprocal, fc = 1/Tc, is the clock frequency. … Frequency is measured in units of Hertz (Hz), or cycles per second: 1 megahertz (MHz) = 106 Hz, and 1 gigahertz (GHz) = 109 Hz.
What is the minimum clock period for the circuit shown above?
Question: Question 11 (5 point) Consider the two-stage circuit shown in Figure 1. Blocks H. combinational circuits. Blocks A, B, C, D, E, F All the registers have the same timing characteristics (propagat setup delay Isetup = 60 ps).
How long is a clock cycle?
Clock time (CT) is the period of the clock that synchronizes the circuits in a processor. It is the reciprocal of the clock frequency. For example, a 1 GHz processor has a cycle time of 1.0 ns and a 4 GHz processor has a cycle time of 0.25 ns.
How do you find the maximum clock frequency?
The maximum clock frequency is fc = 1/Tc = 3.33 GHz. The short path also remains the same at 55 ps. The hold time is effectively increased by the skew to 60 + 50 = 110 ps, which is much greater than 55 ps. Hence, the circuit will violate the hold time and malfunction at any frequency.
How is the minimum clock period calculated?
The minimum clock period is 1.5+3+1.5+0.5=6.5 ns. 2. There are no hold time violations because the minimum flip flop propagation delay is larger than the hold time plus the skew. The maximum delay for the next state logic is 5 ns.
What is clock rate and clock cycle?
A clock cycle is a single period of an oscillating clock signal. Clock speed, rate, and frequency are used to describe the same thing: the number of clock cycles per second, measured in Hertz (Hz).
How do system clocks and bus clocks differ?
Main difference between system clocks and bus clocks as follows: The system clock regulates the CPU and other components (including the buses). there are however, some bus clocks which regulate themselves or, in other words, function according to their own clocks. Bus clocks are generally slower than system clocks.
What happens in a clock cycle?
A clock cycle, or simply a “cycle,” is a single electronic pulse of a CPU. During each cycle, a CPU can perform a basic operation such as fetching an instruction, accessing memory, or writing data. … The frequency of a processor is also known as the processor’s clock speed.
What is clock cycle time for a 2.5 GHz?
It takes 5 clock cycles to complete an instruction operating at 2.5GHz.
