Xtensa Architecture White Paper - Find out more about the great modern architecture behind all of Tensilica's processor cores and why it helps deliver the lowest power and highest performance and code density in the industry.
Xtensa ISA Reference Manual - The Xtensa Instruction Set Architecture (ISA) is a new post-RISC ISA targeted at embedded, communication, and consumer products. This manual describes the Xtensa ISA - both the core architecture and the architectural options.
Xtensa 7 Data Book and Xtensa LX2 Data Book - These two manuals introduce the many features that comprise Tensilica's configurable and extensible Xtensa X7 and Xtensa LX2 processors. Topics in these manuals include memory-management model types, multiple processor (MP) features, Xtensa software development tools, Tensilica Instruction Extension language (TIE), Processor Interface (PIF), and much more. The Xtensa LX2 Micrprocessor Data Book also includes information about its added features, such as FLIX instructions, TIE ports and queues, and the HIFI 2 Audio Engine.
HiFi 2 Audio Engine ISA Resference Manual - This manual is a description of the Instruction Set Architecture (ISA) of Tensilica's HiFi 2 Audio Engine, a highly optimized audio processor. This manual includes in-depth information about the specialized audio instructions: DSP, bit stream, and variable-length encode and decode.
Tensilica Bus Designers Toolkit - Tthe Tensilica Bus Designer's Toolkit, known as PIFKit, is a set of verification components, diagnostic tests, and example test benches for verifying Xtensa Processor Interface (PIF) RTL bridges and other components. PIFKit allows you to test PIF RTL components using generic verification components that are tailored for easy and complete verification. This document describes the components of PIFKit and the PIFKit test bench and diagnostic tests.
