Before you have "brain-splode syndrome" from seeing a 100-core processor for Android 4.0 devices, keep in mind that those 100 cores are actually 96 Stem-Cell Programmable Media Processing Cores that are designed to work in tandem with the 4 primary cores of this new ZiiLabs ZMS-40 CPU. Technically it is really just a quad-core 1.5GHz ARM Cortex-A9; however, it can utilize all those "mini-cores" to offload multiple tasks from the primary cores, and is specifically optimized for Ice Cream Sandwich devices. The primary result/advantage of this design is that it will be twice as powerful, but utilize half the power of their current designs.
Supposedly we will see tablets at CES next week powered by this new tech. If their product lives up to their claims, then we could have a serious contender for the CPU market in Android devices for the future. You can read their full press release at the source link below for more details.
