Freescale Semiconductor launched the quad-core MSC8154 digital signal processor (DSP). The MSC8154 is manufactured using 45-nm process technology and is pin- and code-compatible with the MSC8156 device. This enables designers to use the same board design for lower bandwidth macro- or micro-base station designs. Freescale is currently sampling the MSC8154, with general availability planned for October 2009. Housed in a 783-pin FC-PBGA package, it is offered at 1GHz core speeds. Suggested resale pricing is expected to start at $165 (USD) in 10K volumes.

The MSC8154 dsp features four fully-programmable 1GHz DSP cores delivering 4GHz of DSP processing power. The device also includes the MAPLE-B multi-standard baseband specific accelerator. The SC3850 DSP core enables the MSC8154 to deliver up to 32 GMACS of 16-bit performance. The processor features high speed standard interfaces (Dual sRIO, Dual SGMII, Dual DDR-3 and PCI Express technologies) and large embedded multilevel memory with high speed DDR interfaces.
The MSC8154 DSP’s onboard Multi-Accelerator Platform Engine technology for baseband, called MAPLE-B, works in concert with the four DSP cores to support the 3G-LTE, TDD-LTE, TD-SCDMA and WiMAX standards, as well as the symbol rate functionality of HSPA+. Delivering multi-standard capabilities on a single platform eliminates the need to redesign hardware for different base station standards, so the device is scalable across macro-, micro- and pico-base station form factors.
