Roughly divided into four types
1, RAM
Introduction:
the ARM architecture, formerly known as Advanced RISC Machine (Advanced RISC Machine, referred to earlier: Acorn RISC Machine), is a 32-bit reduced instruction set (RISC) processor architecture, which are widely used in many embedded system design.
Features:
. A small size, low power consumption, low cost, high performance;
B can be well compatible with 8/16-bit device;.
C using RISC architecture, extensive use of registers, instruction execution faster;.
D. most operations are done in the data register; flexible and simple addressing modes, high efficiency;
scenario:
industrial control
network applications
consumer electronics
imaging and security products
2, X86 / Atom
Introduction: xx86 is the Intel 80x86 or Intel first developed a manufacturing microprocessor architecture Pan said. Importantly, the x86 architecture is a variable instruction length CISC (Complex Instruction Set Computer). Intel Atom (Atom) is an Intel ultra-low voltage processor family. The processor using 45-nanometer manufacturing process, integrated 47 million transistors. L2 cache to 512KB, support SSE3 instruction set, and VT virtualization technology.
Features:
. A fast, powerful single instruction.
B. the number of instructions a relatively low bandwidth requirements, simple control, data expressed in binary.
Scenario:
low-end computer
3, MIPS
Introduction:
MIPS is the world's very popular as a RISC processor. MIPS means "no internal interlocked pipeline stages of the microprocessor", the mechanism is the use of software as much as possible way to avoid data-related issues in the pipeline.
Features:
a.MIPS support 64bit instruction and operations, ARM currently only to 32bit. b.MIPS the ARM core registers twice as many, so the MIPS performance of the same power lower than ARM, the ARM higher performance than the same power.
Scenario:
game consoles
router
laser printer
all aspects of handheld computers
4, PowerPC
Description:
PowerPC is a reduced instruction set (RISC) architecture of the central processing unit (CPU), its basic design from IBM (International Business Machines) the IBMPowerPC 601 POWER microprocessor architecture.
Features:
. A good scalability
b convenient and flexible.
