How would you calculate the theoretical throughput of a bus?
A) Bus width x CPU clock speed
B) Installed RAM in bytes x bus clock speed
C) Bus width x bus clock speed
D) Installed RAM in bytes x CPU clock speed
E) Just look at the speedometer. Try to keep it under the limit next time.
The answer: C) Bus width x bus clock speed
The speed of a system bus is independent of any installed memory or individual processor speeds.

Watch “Bus Architectures and Expansion Slots.” An important consideration of the very first IBM personal computer was including standardized expansion slots so the end-user could customize their system. In this video, you’ll learn about bus architectures and expansion slots, including PCI, PCI Express, AGP, and CardBus. |
