TM
64-/32-BIT MICROPROCESSOR
DESCRIPTION
The
μ
PD30550 (V
R
5500) is a member of the V
R
Series
TM
of RISC (Reduced Instruction Set Computer)
microprocessors. It is a high-performance 64-/32-bit microprocessor that employs the RISC architecture developed by
MIPS
TM
.
The V
R
5500 allows selection of a 64-bit or 32-bit bus width for the system interface, and can operate using
protocols compatible with the V
R
5000 Series
TM
and V
R
5432
TM
.
Detailed function descriptions are provided in the
V
