DESCRIPTION
The
µ
PD30500 (VR5000),
µ
PD30500A
Note
(VR5000A), and
µ
PD30500B
Note
(VR5000B) are a high-performance,
64-bit RISC (Reduced Instruction Set Computer) type microprocessors employing the RISC architecture developed
by MIPS
TM
Technologies Inc.
The instructions of the VR5000, VR5000A, and VR5000B are compatible with those of the VR3000
TM
series and
VR4000
TM
series and higher, and completely compatible with those of the VR10000
TM
. Therefore, present applications
can be used as they are.
Note Under development
Detailed functions are descrided in the following manual. Be sure to read the manual when
designing your system.
