White Paper: TIE - The Fast Path to High Performance Embedded SOC Processing

TIE, Tensilica’s Instruction Extension language, is a simple way to make Xtensa processor cores faster and more efficient by adding new task-optimized instructions and I/O interfaces.TIE looks a lot like Verilog, but anyone can learn the basics of TIE in a few minutes whether they already know how to write Verilog descriptions or not. Just a few lines of TIE can make a dramatic difference in an Xtensa processor’s performance and flexibility for targeted tasks. Xtensa processors with TIE customizations can compute and move data tens or hundreds of times faster than conventional processor cores. As a result, your SOC gets smaller, cheaper, and faster and it will consume less power. http://www.tensilica.com/products/literature-docs/white-papers/tie---the-fast-path.htm
