Introduction

The TS68882 is a high-performance floating-point device designed to interface with the

TS68020 or TS68030 as a co-processor. This device fully supports the TS68000 virtual

machine architecture, and is implemented in HCMOS, Atmel’s low power, small geome-

try process. This process allows CMOS and HMOS (high-density NMOS) gates to be

combined on the same device. CMOS structures are used where speed and low power

is required, and HMOS structures are used where minimum silicon area is desired. The

HCMOS technology enables the TS68882 to be very fast while consuming less power

than comparable HMOS, and still have a reasonably small die size.

With some performance degradation, the TS68882 can also be used as a peripheral

processor in systems where the TS68020 or TS68030 is not the main processor (i.e.,

TS68000, TS68010). The configuration of the TS68882 as a peripheral processor or co-

processor may be completely transparent to user software (i.e., the same object code

may be executed in either configuration).

The architecture of the TS68882 appears to the user as a logical extension of the

TS68000 Family architecture. Coupling of the co-processor interface allows the

TS68020/TS68030 programmer to view the TS68882 registers as though the registers

are resident in the TS68020/TS68030. Thus, a TS68020 or TS68030/TS68882 device

pair appears to be one processor that supports seven floating-point and integer data

types, and has eight integer data registers, eight address registers, and eight floating-

point data registers.

As shown in Figure 1, the TS68882 is internally divided into four processing elements;

the Bus Interface Unit (BIU), the Conversion Control Unit (CCU), the Execution Control

Unit (ECU), and the Microcode Control Unit (MCU). The BIU communicates with the

main processor, the CCU controls the main processor communications dialog and per-

forms some data conversions, and the ECU and MCU execute most floating-point

calculations.

The BIU contains the co-processor interface registers, and the 32-bit control, and

instruction address registers. In addition to these registers, the register select and

DSACK timing control logic is contained in the BIU. Finally, the status flags used to mon-

itor the status of communications with the main processor are contained in the BIU.

The CCU contains special-purpose hardware that performs conversions between the

single, double, and extended precision memory data formula and the internal data for-

mat used by the ECU. It also contains a state machine that controls communications

with the main processor during co-processor interface dialogs.

The eight 80-bit floating-point data registers (FP0-FP7) are located in the ECU. In addi-

tion to these registers, the ECU contains a high-speed 67-bit arithmetic unit used for

both mantissa and exponent calculations, a barrel shifter that can shift from 1-bit to 67-

bits in one machine cycle, and ROM constants (for use by the internal algorithms or user

programs).

The MCU contains the clock generator, a two-level microcoded sequencer that controls

the ECU, the microcode ROM, and self-test circuitry. The built-in self-test capabilities of

the TS68882 enhance reliability and ease manufacturing requirements; however, these

diagnostic functions are not available to the user.
