On a growth curve
XMOS has now labeled its silicon as the xCore multicore microcontrollers and claims they have the low latency, fast I/O response and
deterministic performance required for real-time applications in consumer, audio, industrial, and automotive markets.
XMOS silicon continues to be the XS1-L1, XS1-L2 and XS1-G4. These have 1, 2 and 4 physical processor cores, respectively. However, XMOS is stressing the ability to host 8, 16 and 32 logical cores on these chips respectively.
This is enabled through the eight-fold time-slicing of processing that is done to better match memory access to the ALU pipeline performance. The availability of these "virtual" processors cores is a key part of the performance and responsiveness of the chips and is reflected upwards through the software development stack.
"The embedded market represents a $76 billion opportunity overall, and our xCore multicore microcontrollers offer significant advantages over traditional MCUs. xTIMEcomposer and xSOFTip allow developers familiar with C to access deterministic multicore performance more easily than ever before," said Nigel Toon, President and CEO of XMOS.
"System designers understand the limitations of traditional 8-, 16- and 32-bit MCUs in embedded applications, but they like their ease of use and simple development environments," Nigel continued. "They are now looking to multicore alternatives that can meet critical I/O response times, perform multiple tasks concurrently and support new interface standards: but they want the same easy-to-use development environment. As embedded systems continue to become more complex, xCore, supported by xTIMEcomposer and xSOFTip, meets this rapidly growing need."
