XU6--QF6A Datasheet

Ports

The I/O pins are connected to the processing cores by Hardware Response

ports. The port logic can drive its pins high and low, or it can sample the value on

its pins optionally waiting for a particular condition. Section 6.

Clock blocks

xCORE devices include a set of programmable clock blocks that can be

used to govern the rate at which ports execute. Section 6.

Memory

Each xCORE Tile integrates a bank of SRAM for instructions and data, and

a block of one-time programmable (OTP) memory that can be congured for system

wide security features. A memory buffer can be used to implement software dened

memory. Section

Dual PLL

One PLL is used to create a high-speed processor clock given a low speed

external oscillator. A secondary PLL is for user application. Section

USB

The USB PHY provides High-Speed and Full-Speed, device, host, and on-the-go

functionality. Data is communicated through ports on the digital node. A library is

provided to implement USB device functionality. Section

JTAG

The JTAG module can be used for loading programs, boundary scan testing,

in-circuit source-level debugging and programming the OTP memory. Section

Software

Devices are programmed using C, C++ or xC (C with multicore extensions). XMOS pro-

vides tested and proven software libraries, which allow you to quickly add interface and

processor functionality such as USB, Voice, Ethernet, PWM, graphics driver, and audio

EQ to your applications.

xTIMEcomposer Studio

The xTIMEcomposer Studio development environment provides all the tools you need to

write and debug your programs, prole your application, and write images into ash mem-

ory or OTP memory on the device. Because xCORE devices operate deterministically,

they can be simulated like hardware within xTIMEcomposer: uniquely in the embedded

world, xTIMEcomposer Studio therefore includes a static timing analyzer, cycle-accurate

simulator, and high-speed in-circuit instrumentation.

The tools are supported on Windows, Linux and MacOS X and available at no cost from

xmos.ai/downloads. Information on using the tools is provided in the xTIMEcomposer

User Guide, X6 .
