TS68882  
Description  
The TS68882 enhanced floating-point co-processor is a full implementation of the  
IEEE Standard for Binary Floating-Point Arithmetic (754) for use with the THOMSON  
TS68000 Family of microprocessors. It is a pin and software compatible upgrade of  
the TS68881 with optimized MPU interface that provides over 1.5 times the perfor-  
mance of the TS68881. It is implemented using VLSI technology to give systems  
designers the highest possible functionality in a physically small device.  
Intended primarily for use as a co-processor to the TS68020/68030 32-bit micropro-  
cessor units (MPUs), the TS68882 provides a logical extension to the main MPU  
integer data processing capabilities. It does this by providing a very high performance  
floating-point arithmetic unit and a set of floating-point data registers that are utilized  
in a manner that is analogous to the use of the integer data registers. The TS68882  
instruction set is a natural extension of all earlier members of the TS68000 Family, and  
supports all of the addressing modes of the host MPU. Due to the flexible bus inter-  
face of the TS68000 Family, the TS68882 can be used with any of the MPU devices of  
the TS68000 Family, and it may also be used as a peripheral to non-TS68000  
processors.
