Nonvolatile processors offer a number of desirable properties including instant on/off, zero standby power and resilience to power failures. This paper presents a fabricated nonvolatile processor based on ferroelectric flip-flops. These flipflops are used in a distributed fashion and are able to maintain system states without any power supply indefinitely.(More)
Nonvolatile (NV) processors have attracted much attention in recent years due to their zero standby power, resilience to power failures, and instant-on feature. One design challenge of NV processors is the excess area needed by NV registers. This paper introduces a parallel compare and compress (PaCC) architecture to reduce such excess area. A key component(More)
This paper presents an OFDM transceiver for wireless LAN systems and its baseband transceiver architecture. We study the optimum parameters about DFT size, guard interval, symbol duration, and number of subcarriers in an 80-MHz bandwidth by extending the IEEE 802.11a standard. The proposed transceiver has a maximum 300-Mbps transmit rate and achieves 600(More)
In this paper we report our works on designing MIMO wireless LAN system with throughput 600 Mbps for 30 meter propagation range by using Generalized Layered Space Time (GLST) coding and its implementation on field programmable gate array (FPGA) chips. At the receiver we employ our low-complexity GLST decoder to maintain error performance with low(More)
