XS1 Family Product Brief

XMOS XS1 Product Family
XMOS has developed the next generation of 32-bit user-defined embedded
processors that significantly lower development time and system bill of
materials cost. The XCore® event-driven deterministic processor combines
the code efficiency of a RISC processor, the computational performance of a
DSP and the unique flexibility of implementing all peripherals through user-
s
defined "C" software.

The XS1-G and XS1-L Series
e
XS1 devices feature a multi-threaded processor architecture constructed from XCoreTM
processors connected by communication links. The architecture is scalable and any
number of XCoreTM processors can be connected together. The family contains the high-
performance G-series and the energy-efficient L-series.
Applications are developed using a combination of
XS1-G4
XC, C and C++. XC provides extensions to C that

Family Line-up
The XS1 family is available in a range of densities from one to four XCoresTM providing
development opportunities for a wide range of scalable embedded systems.
XS1-G devices are fabricated on TSMC's 90nm process technology and allow larger
systems to be contained in a single chip.
The 65nm XS1-L devices are optimized for low power while still delivering a significant
amount of processing performance for DSP, interfacing and general processing tasks.

Development tools to go from concept to production
The XMOS development tools are based on a standard embedded software flow that
supports C, C++ and XC. As well as providing compilers and a debugger, the tools validate
that hard real-time constraints are met on target devices. Utilities to deploy program images
onto flash memory during device manufacture,
and to upgrade them in-field, are included.
