Abstract: Disclosed are call processing methods which are performed by a network terminator located at a subscriber's premises. The network terminator is coupled to a digital network and a communication device at the subscriber's premises and can perform call waiting, caller identification, call conferencing without intervention from a telco's switching system that requires an additional charge to the subscriber for these services. In addition, the network terminator can perform a method which allows two digital communication devices coupled to one S-bus to share a communication session. In another embodiment, up to a six way conference call can be established with an analog telephone coupled to an ISDN network via the network terminator of the present invention.

Abstract: An enhanced microprocessor (278) (FIG. 6) having a first portion (153) (FIG. 7) and a second portion (196) (FIG. 8) configured to eliminate prefetching of instructions from an instruction cache (102) (FIG. 6) when the required instructions are already present within a prefetch buffer (104) (FIG. 6). The first portion (153) and second portion (196) are in circuit communication with a prefetch buffer (104) (FIG. 6), branch target cache (108) (FIG. 6), control unit (110) (FIG. 6), and execution unit (112) (FIG. 6). The first portion (153) is responsive to forward or backward branch instructions that have a branch target within the same prefetch buffer, and to forward branch instructions that have a branch target within a next successive prefetch buffer. The first portion (153) is configured to inhibit prefetching of instructions when such conditions are present.
