MSM7000 is a series of system-on-a-chip processors manufactured by Qualcomm for handheld devices, especially smartphones.

These SOCs have multiple processing cores but unlike contemporary processor chips like AMD's Athlon/Phenom and Intel's Core series, these multiple cores are not available in the OS to run applications that have symmetric multiprocessing properties. There is only one core to run the OS and user applications.

Generally these SOCs have the following 4 cores:^[1]

• Applications processor, ARM1136J-S, running Windows Mobile / Android / Linux / etc.
• Applications DSP, QDSP5000, does coding/decoding for media.
• Baseband processor, ARM9, running a real-time OS and the GSM stack
• Baseband DSP, QDSP4000, does coding/decoding for telephony

Apart from the CPU cores the chips contain such hardware as 2D graphics hardware, 3D (OpenGL ES 1.1) graphics hardware, media acceleration hardware (for video decode, etc.), and various interfaces (keyboard, display / MDDI, USB, camera, TV, etc.). They also contain an AXI controller, a kind of memory control unit.

They are widely used in smartphones produced by HTC Corporation (including both Windows Mobile and Android devices), Sony Ericsson, LG Group, Samsung, ZTE, and also other devices like the Zeebo.
