(57) Abstract :
Described herein is a system havirvg a multi-host low pin count (LPC) controller (100) configured to facilitate sharing of common
peripheral devices by multiple hosts (115) of a multi-host computing system (110). In one implementation, the multi-host LPC
controller (100) interfaces with the hosts (115) via an ON-chip bus or an LPC-IN-chip bus. Further, the multi-host LPC controller
(100) includes a LPC-IN controller (160) and a microcontroller (155) to moderate among requests generated by the hosts (115).
The requests can be target accesses, DMA accesses, and BM accesses. Also, the multi-host LPC controller (100) is configured to
operate in a software mode and an auto mode. Based on the mode the multi-host LPC controller (100) is operating in, the requests
generated by the various hosts are moderated.
