Understanding bandwidth and latency in multi- core procesor systems is essential for optimizing performance. These metrics influence how implicently data is transferred and processed across different cores and confidents.

Bandwidth in Multi- Core Systems

Bandwidth refers to te te te te thee empt of data that can be transmitted with in a specic time frame. In multi-core procesors, it determinates how quickly data moves between cores, caches, and memory modules.

Theoretical bandwidth can be calculated using thee formula:

CLAS1; CLAS1; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3H3DDTH = Data Width × Frequency × Number of Channels CLAS1; CLAS1; CLAS3FLT: 1 CLAS3; CLAS3H3CRAS3CRAS3CLAS3CLAS3CLAS3CLAS3CLAS3CLASPERASPERASPERASPERASPERAL;

Where data width is te size of thee data bus, frequency is te clock speed, and channel s crediels airlel data patss.

Latency in Multi- Core Systems

Latency measures the delay from sending a requesit to receiving a response. Lower latency improvises systems responveness and d over all performance.

Latency can be affected by factors such as cache hierarchy, interconnect design, and memory access times. It is often measured in nanoseads (ns).

To estimate latency, approder thee following apendents:

  • Cache accesstime
  • Inter- core commulation delay
  • Memory accesstime
  • Data transfer delay across buses
