The Snapdragon and Cortex A8 are both implementations of the ARM V7A architecture, but are completely separate designs. The Snapdragon is Qualcomm's version and is unique to Qualcomm, whereas the Cortex A8 is licensed by ARM to third parties.
It's the same as Intel and AMD both making x86 chips; the ISA is the same but the design is different. However, ARM is more than happy to let Qualcomm design thier own.
- jws 17y agoAh, yes. I misread the wikipedia page. similar to A8, not A8.
- jjfromchicago 17y agoI thought Cortex A8 was TI's implementation of ARMv7 and Snapdragon Qualcomm's: the ISAs are the same but Snapdragon can run distinct cores at distinct speeds because of disjoint caches per core, beneficial for power savings, for example. Check http://www.arm.com/miscPDFs/14128.pdf http://www.arm.com/miscPDFs/14128.pdf for more details than are simple to read.
- timthorn 17y agoNo, the Cortex A8 hard macro was designed with TI as a lead customer, but is an ARM design.
