Computer architecture deeper pipeline

What is a deeper pipeline?
As the pipeline is made "deeper" (with a greater number of dependent steps), a given step can be implemented with simpler circuitry, which may let the processor clock run faster.
Such pipelines may be called superpipelines.
A processor is said to be fully pipelined if it can fetch an instruction on every cycle..
What is pipeline depth in computer architecture?
Pipeline terminology
The pipeline depth is the number of stages—in this case, five.
In the first four cycles here, the pipeline is filling, since there are unused functional units.
In cycle 5, the pipeline is full.
Five instructions are being executed simultaneously, so all hardware units are in use..

What is pipeline strategy in computer architecture?
What is a pipeline in a CPU? Pipelining is a technique for breaking down a sequential process into various sub-operations and executing each sub-operation in its own dedicated segment that runs in parallel with all other segments..
Why are deeper pipelines better?
The depth of the pipeline is often increased to achieve higher clock rates.
The less logic per stage, the smaller the clock period can be and the higher the throughput..
Why is pipelining important in computer architecture?
The biggest advantage of pipelining is that it reduces the processor's cycle time.
This is because it can process more instructions simultaneously, while reducing the delay between completed instructions..
11 Pipeline Hazards
Pipelining doesn't help latency of single task, it helps throughput of entire workload.Pipeline rate limited by slowest pipeline stage o Multiple tasks operating simultaneously.Potential speedup = Number of pipe stages.Unbalanced lengths of pipe stages reduces speedup.
The maximum number of pipeline stages is limited by pipeline hazards, sequencing overhead, and cost.
Longer pipelines introduce more dependencies.
Some of the dependencies can be solved by forwarding but others require stalls, which increase the CPI.

A “classic” pipeline of a Reduced Instruction Set Computing (RISC) architecture consists of five stages2: instruction fetch, instruction decode, instruction

Adding registers into the design is similar to higher-level architectural design partitioning. Adding registers to the design will result in a “deeper” pipeline through the design. The resource penalty of additional registers allows the highest level of performance possible.

Instruction pipelines are a fundamental element of how a DSP achieves its high order of performance and significant operating speeds. When any processor
