Key features
Feature packed
XCORE.AI is a unique programmable processor array which features:
- 16 hardware threads (HART) split between 2 multi-threaded processor ‘tiles’
- Each tile is equipped with 512kB of SRAM and an integer vector unit capable of efficient block floating point, enabling every HART to execute a common set of control, DSP, AI and IO instructions.
XMOS provide a comprehensive set of high-level functions such as: PDM interfaces, acoustic echo cancellation, noise suppression, asynchronous sample rate conversion, automatic gain control and many others. These are packaged as reference applications that can be readily modified and extended to match unique system functionality and interface requirements all within a single, cost-effective device.
Flexibility
XCORE enables whole DSP systems to be built with the lowest system bill of materials, including significant DSP workloads in both fixed- and floating-point formats.
The platform’s flexibility enables solutions that integrate other key components, for example IO protocols, control algorithms and even AI. Uniquely with XCORE, these entire DSP systems can be built using software alone.
Programmability
XCORE delivers world‑leading predictable programmability, essential for DSP applications requiring hard real‑time performance.
XCORE’s unique architecture ensures that different parts of the system do not interfere with each other, delivering the robustness, low‑latency and guaranteed execution time required by DSP systems, especially those supporting multiple sample rates.
Scalability
A powerful inter‑processor communication infrastructure provides high speed communication between any number of XCORE.AI chips seamlessly extending performance and memory.
