A new generation of ORCA FPGA with enhanced features and performance

Abstract

This paper describes the new AT&T Optimized Reconfigurable Cell Array (ORCA) 2CA and 2TA series of Field-Programmable Gate Arrays (FPGAs). Both series are based on the ORCA 2C/T architecture, but migrated to the advanced AT&T 0 . 3 5~ CMOS processes. These two processes are individually optimized for SV and 3.3V operations. In addition, architectural innovations are incorporated into the new series to enhance both performance and functionality. These include:Efficient support of parallel multiplier Efficient support of synchronous single-port and dual-port Streamlined creation of large memory using port-enable Easy system integration with the 5V-tolerant inputloutput buffers, found on the 3.3V 2TA series.As the result, the ORCA 2CAl2TA arrays are significantly smaller and 15%/30% faster (PFU speed) than the corresponding 0 . 5~ 2C/T arrays. memories control and internal tristate buffers
