Forward Pass Calculation for KV Cache Population
A system is populating a Key-Value (KV) cache for a 2048-token input sequence. Contrast the number of forward passes required for a single-pass approach versus a chunked approach that processes the input in 512-token segments. Explain the underlying reason for this difference in processing.

A large language model is processing a long input sequence to populate its Key-Value (KV) cache before starting token generation. Which statement best analyzes the fundamental difference between processing the entire sequence in a single forward pass versus processing it in sequential segments?
