GENERAL DESCRIPTION
The Am29000 and the low-cost Am29005
lined Instruction microprocessors are high-perfor-
mance,
general-purpose,
32-bit
implemented in CMOS technology. They support a vari-
ety of applications by virtue of a flexible architecture and
rapid execution of simple instructions that are common
to a wide range of tasks.
Both processors efficiently perform operations common
to all systems, while deferring most decisions on system
policies to the system architect. They are well-suited for
application in high-performance workstations, general-
purpose super-minicomputers, high-performance real-
time controllers, laser printer controllers, network
protocol converters, and many other applications where
high performance, flexibility, and the ability to program
using standard software tools is important.

Stream-
The Am29000 and Am29005 microprocessor instruc-
tion sets have been influenced by the results of high-lev-
microprocessors
el language, optimizing compiler research. They are
appropriate for a variety of languages because they effi-
ciently execute operations that are common to all lan-
guages. Consequently, the Am29000 and Am29005
microprocessors are an ideal target for high-level lan-
guages such as C, FORTRAN, Pascal, Ada, and CO-
BOL.
The Am29000 and Am29005 microprocessors are
available in a 168-lead Plastic Quad Flat Pack (PQFP)
package. The package has 141 signal pins and 27 pow-
er and ground pins. The Am29000 microprocessor is
also available in a 169-lead Pin Grid Array (PGA) pack-
age. The PGA has 141 signal pins, 27 power and ground
pins, and 1 alignment pin.
