EFPTM Microcode Products for Expedited Fast-Path Processing
"Arabella's clever software mines up to 10x throughput from PowerQUICC processors, and resident skeptic Lee Goldberg is a believer!" (www.analogzone.com, August 8, 2005)
Arabella Software’s EFP product line is a revolutionary line of all software solutions designed to boost system level throughput of PowerQUICC based designs up to 10 times that of existing software packages. The EFP products empower PowerQUICC™ processors with an unparalleled level of performance for a wide range of applications, handling in excess of 1Gbps of traffic, or well over half a million packets per second.
The EFP product line is based on an innovative system level concept developed by Arabella called "Asymmetrical Multi-Processing" (AMP). AMP exploits the fact that most embedded communications applications can be partitioned into fast-path and slow-path functions. Fast-path operations are implemented in CPM or QE microcode and aggressively optimized for maximum performance. Algorithms, instruction ordering and use of DMA operations are carefully chosen to best suit the characteristics of the CPM/QE. The microcode interfaces with slow-path software running on the PowerPC under standard operating systems such as Linux. The asymmetry of the application (fast/slow-paths) is matched by the asymmetry of the two processors (fast/generic). By aligning these carefully, the EFP products can increase performance several orders of magnitude over the current state-of-the-art.
EFP Products are availabe as complete EFP Solutions that include the Arabella Linux operating system and associated protocols, Microcode Packs for adding high performance acceleration to exisitng communications software, and Microcode Modules for individual acceleration functions.
Sizzling Speed
Based on Arabella's Asymmetrical Mutli-Processor architecture, the EFP products offer unparalleled performance on standard PowerQUICC processors. Hand-crafted microcode accelerators are used to boost performance to levels that will not be surpassed on standard PowerQUICC processors. No hardware changes are required to use EFP.
EFP Solutions
EFP Solutions are comprised of microcode and an EFP-aware version of Arabella Linux, provided as a complete, integrated and highly optimized solution for a particular application. Performance is known up front removing uncertainties from benchmark results and saving customers from having to integrate packages from multiple sources only to find out that the combined solution falls short of performance expectations. You can choose the right processor up front with full confidence that throughput numbers can be met. EFP solutions include:
- **NEW** EFP PPP
-Includes PPP, PPPoE, ML/MC-PPP, PPPoA and PPPmux
-Designed for high-speed PPP switching or termination over HDLC,Ethernet or ATM
-Supports RFC's 1661, 1662, 1990, 2686, 2516 and 3153
-Performance is approx 400,000 packets per second on a 333MHz CPM processor

EFP Microcode Packs
EFP Microcode Packs are the microcode-only components of EFP Solutions. Microcode Packs can be integrated into proprietary protocol stacks from other vendors, or integrated into your exiting software stacks resulting in up to 10 times the system level throughput than you are currently achieving. Arabella can perform this integration as part of a service contract.
