Phybit Soft Processors
Phybit provides two types of wireless-specific soft processors as part of our solution delivery process. These are the H2 family of signal processors and the L2 family of protocol processors. We program and on occasions customize each processor to perfectly match the size, cost, and performance requirements of the end products within which they will be used.
Wide Range of Applications
- Wireless Base Stations: LTE eNB PHY and MAC Layer Processors
- Access Points: WLAN 802.11abgn PHY and 802.11sti Protocols
- Picocell and Femtocells: PHY and MAC Chipsets
- Remote Relay Equipment: PHY and MAC processors
- Wireless Backhaul: Point-to-Point Digital Microwave Modems
Software-Defined Microarchitectures: The Phybit Way
Phybit soft processors are based on the SPARC V8 specifications, implemented with our own HDL. We have extended the instruction set of V8 and optimized the microarchitecture for wireless applications. Unlike other ASIPs (application-specific instruction set processors), which must be designed from scratch for each new function, our soft processors are re-usable for a class of applications. This means that Phybit soft processors can be used for a wider class of applications and in a larger variety of end products.
Processor Families: H2 and L2 Series
Phybit enhancements to V8 efficiently support hard realtime algorithms for protocol stacks, security, physical layer, channel coding, and scheduling functions. We provide 5 soft processor microarchitectures in two families:
- H2ASVP: Application-Specific Vector Processor
- H2FEC: Programmable Channel Processor for Forward Error Correction
- L2PRO: Protocol Processor for MAC and RLC
- L2SEC: Wireless Security Processor
- L2IMP: Idle Mode Processor
All are delivered as synthesizable HDL with testbenches and verification suites.
