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 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.
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.
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
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.
