Description
The IMP is a very large-scale integration (VLSI) device incorporating the main building
blocks needed for the design of a wide variety of controllers. The device is especially
suitable to applications in the communications industry. The IMP is the first device to
offer the benefits of a closely coupled, industry-standard, TS68000/TS68008 micro-
processor core and a flexible communications architecture. This multichannel
communications device may be configured to support a number of popular industry
interfaces, including those for the integrated services digital network (ISDN) basic rate
and terminal adapter applications. Through a combination of architectural and pro-
grammable features, concurrent operation of different protocols is easily achieved
using the IMP. Data concentrators, line cards, bridges, and gateways are examples of
suitable applications for this versatile device.
The IMP is a high-density complementary metal-oxide semiconductor (HCMOS)
device consisting of a TS68000/TS68008 microprocessor core, a system integration
block (SIB), and a communications processor (CP). The TS68302 block diagram is
shown in Figure 1.
Note:
GCI is sometimes referred to as IOM2.
