MOTOROLA DSP96002 USER’S MANUAL 1 - 1
SECTION 1
DSP96002 INTRODUCTION
This manual describes the first member of a family of dual-port IEEE floating point programmable CMOS
processors. The family concept defines a core as the Data ALU, Address Generation Unit, Program Con-
troller and associated Instruction Set. The On-Chip Program Memory, Data Memories and Peripherals sup-
port many numerically intensive applications and minimize system size and power dissipation; however,
they are not considered part of the core.
The first family member is the DSP96002. The main characteristics of the DSP96002 are support of IEEE
754 Single Precision (8 bit Exponent and 24 bit Mantissa) and Single Extended Precision (11 bit Exponent
and 32 bit Mantissa) Floating-Point and 32 bit signed and unsigned fixed point arithmetic, coupled with two
identical external memory expansion ports. Its features are listed below.
