The author of this web content discusses the bus cycle timings and behavior of the Intel 8088 processor. They explain that the traditional model of a 4-cycle bus cycle time is incomplete and does not provide an accurate representation of the 8088’s operation. Instead, they propose a new model that accounts for additional pipeline states and bus delays. This new model suggests that the total bus cycle time of the 8088 is actually 7 cycles. The author goes into detail about various scenarios and provides diagrams to illustrate their findings. They also mention the importance of prefetching and the impact of factors such as queue fullness and interrupt handling on bus timings. Overall, the content reveals a deeper understanding of the 8088’s behavior and challenges the traditional understanding of its bus cycle timings.
