TS68020
2115A–HIREL–07/02
Other microprocessors in the TS68000 Family can operate any TS68000 co-processor
even though they may not have the hardware implementation of the co-processor inter-
face as does the TS68020. Since the co-processor is operated through the co-
processor interface registers which are accessed via normal asynchronous bus cycles,
the co-processor may be used as a peripheral device. Software easily emulates the
communication protocol by addressing the co-processor interface registers appropri-
ately and passing the necessary commands and operands required by the co-
processor.
The co-processor interface registers are implemented by the co-processor in addition to
those registers implemented as extensions to the TS68020 programmer’s model. For
example, the TS68881 implements the co-processor interface registers shown in Table
10 and the registers in the programming model, including eight 80-bit floating-point data
registers and three 32-bit control/status registers used by the TS68881 programmer.
