Abstract
A secure terminal includes a host (105) and slaves (125) which send and receive messages via a peripheral component interconnect (PCI) bus (130). The host allows slaves to receive messages from the host and send messages to the host. The host prevents slave-to-slave communication of messages. The host and each slave include interface logic (120) coupled to the PCI bus and a memory (200) for coupling a processor (110) to the interface logic (120). Each dual-port RAM (200) includes a first memory portion for receiving messages from a sender and a second memory portion for storing messages to be transmitted to a receiver.
