Scalable C-programmable VLIW DSP processor

Scalable C-programmable VLIW DSP processor in 28nm with a commercial tool-chain, ideal for wireless standards, eg LTE Cat4, IEEE802.11n/ac and DVB.

Macro Name  Flexible and highly efficient DSP processor for wireless baseband processing
Type Soft IP
Short Description(max 128 characters)  Scalable C-programmable VLIW DSP processor in 28nm with a commercial toolchain is ideal for wireless standards, eg LTE Cat4, IEEE802.11n/ac and DVB. 
Extra description (optional) Imec offers a whitebox license to its flexible and highly efficient DSP processor (branded BOT) for wireless baseband processing. This processor is C-programmable with customizable instruction set, and comes with a commercial compilation and debug tool chain with support. This 28nm CMOS DSP (a 40 nm version is also available) is developed to meet and exceed the high throughput and low power consumption requirements of the latest wireless standards, such as LTE Cat4 (Cat5 for multi-core DSP), connectivity standards such as WLAN IEEE802.11n and 11ac and others such as DVB. The scalable architecture allows for flexibility at design time as well as at run time, supporting many algorithms, modes and throughput, easy to adapt and extend. Extra and/or customized instructions can be added easily to the core. Compiler, RTL code and SystemC models are automatically regenerated when changes are made to the model or instruction set. This DSP uses a 10-issue slot VLIW design with 32-bit scalar slots and 256-bit vector slots, using a 16-bit fixed point implementation, with parallelism both for instruction and data level.
