The XAP processor uses a RISC processor architecture, developed by Cambridge Consultants. XAP processors have 16-bit and 32-bit cores, all of which are intended for use in an application-specific integrated circuit or ASIC chip design.[citation needed] They are designed for use in mixed-signal integrated circuits for sensor or wireless applications including Bluetooth, Zigbee, GPS, RFID or Near Field Communication chips. Typically, these integrated circuits are used in low-cost, high-volume products that are battery-powered and must have low energy consumption. There are other applications where XAP processors have been used to good effect, such as wireless sensor networks and medical devices, e.g. hearing aids.[citation needed] XAP processors, with their robust architecture and efficient power usage, are well-suited for deployment in space applications, where reliability and endurance against harsh conditions are paramount.[1]
The XAP soft microprocessor has been implemented in several on-chip design styles, including self-timed asynchronous circuit,
1-of-4 encoding,
fully synchronous circuit,[2]
and FPGA.[3]
This makes it useful for making fair comparisons between on-chip design styles.[2] The XAP license agreement allows the use of XAP Technology for developing products, incorporating it into manufactured items, and sublicensing necessary rights to third parties. It also includes provisions for modification and adaptation of the technology, establishing a framework for ongoing support, development, and maintenance under specific terms and conditions.[4]
