According to XMOS Ltd., it has a new event-driven microcontroller which has a lower price. The model is XS1-L4-64.

XMOS indicates that the chip can be used as the lowest-cost multicore microcontroller. The chip has a single physical ALU but support in terms registers and other circuitry for four time-sliced virtual processors. Time slicing is done to better match memory access to the ALU pipeline performance and the availability of these "virtual" processor cores is a key to the performance and responsiveness of the chips.

In the case of XS1-L4-64 it supports four "logical" processors with 64-Mbytes of memory. The chip is supplied in a 48-pin package that is pin-compatible with the existing 6-core L6-64 and the 8-core L8-64 xCore devices which are based on the same silicon die.

The xCore family offers 64-bit precision DSP calculation making the new device suitable for stepper motor control, industrial networking and motion control. The event-driven deterministic nature of the xCore family is helping the company make design wins in robotics applications, the company said.
