Overview

Non-blocking NxN Crossbar with N inputs ports and N output ports can be used in networking switches such as PCI, Ethernet, InfiniBand, etc. It provides direct and low latency (1 cycle) switching from one port to another port. It can work with fixed packet size or variable packet size. No inter stage queue or memory buffers are required as in case of other topology such as Clos network. This reduces the gate count and memory required to implement crossbar. For the same reason, there is no issue with network saturation. It has less number of nets compared with other topology and have no congestion issue. Control for crossbar is decentralized and is easy to implement.

Secure Mobile Payments - Protecting display data in TrustZone-enabled SoCs with the Evatronix PANTA Family of Display Processors

Secure System-on-Chips (SoCs) based on ARM® TrustZone® technology enable both hardware and software components to be isolated as a secure subsystem within a complex SoC and as such focus on processing protected, sensitive and valuable assets, such as payment credentials, whenever these might be endangered with an attack, modification or capture. At the same time the main system software may be an open Rich OS platform that enables downloading and use of arbitrary third-party and non-trusted applications which can gain access to almost all system hardware elements.
