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.

MSM7200, MSM7200A, MSM7201, MSM7201A

[edit]

The A versions have higher specs (frequencies) and a smaller manufacturing process (65 nm vs. 90 nm). The 7x01 versions have a different radio than the 7x00 versions.

Popular phones using these processors:

MSM7500, MSM7501, MSM7500A, MSM7501A

[edit]

Basically the same as the MSM7200, but with CDMA radio replacing the GSM radio. The A versions have higher specs (frequencies) and a smaller manufacturing process (65 nm vs. 90 nm). The 7x01 versions have a different radio than the 7x00 versions.

MSM7600, MSM7601, MSM7600A, MSM7601A

[edit]

Same as the MSM7200A, but with both GSM and CDMA functionality, each of which can be optionally disabled. The A versions have higher specs (frequencies) and a smaller manufacturing process (65 nm vs. 90 nm). The 7x01 versions have a different radio than the 7x00 versions.

Popular phones using these processors:

MSM7x25

MSM7225 and MSM7625 was later included in the Snapdragon S1 family, see Snapdragon S1[broken anchor]

MSM7x27

Qualcomm MSM7227A

MSM7227 and MSM7627 was later included in the Snapdragon S1 family, see Snapdragon S1[broken anchor]

MSM7x30

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
