What is an FPOA? Download FPOA Overview

FPOA stands for Field Programmable Object Array, a reprogrammable device that offers up to four times the performance of an FPGA. The FPOA is a two dimensional array of Silicon Objects. Silicon Objects are 16 bit configurable machines, such as an Arithmetic Logic Unit, Multiply-Accumulator or Register File. Both the Silicon Object behavior and the interconnection among Silicon Objects are field-programmable. Request FPOA Architecture Guide

Silicon Objects

In MathStar's flagship Arrix FPOA, there are three Silicon Object types distributed within the array structure: The Arithmetic Logic Unit (ALU), the Multiply Accumulator (MAC), and the Register File (RF). Additionally, internal RAM is available within the array and external DRAM can be directly connected. The array connects to both high-speed LVDS I/O and general purpose I/O allowing both high bandwidth and flexible I/O configurations. The ratio and placement of different Silicon Objects allow for high-performance Digital Signal Processing applications

FPOA Features

MathStar's second generation FPOA, the Arrix family, is designed for a variety of applications and has the following features:

• 
  
• 400 Silicon Objects with operation up to 1 GHz
  
  • 
    
  • 256 ALUs
    
  • 64 MACs
    
  • 80 RFs
  
  
• Two Bi-directional 500MHz DDR 16-bit LVDS ports (64 Gbps of bandwidth)
  
  
• 96 pins of LVCMOS GPIO, operating either synchronously or asynchronously up to 100 MHz.
  
• Twelve banks of 500MHz internal SRAM memory banks (57 GBytes/sec.)
  
• Two 266 MHz 36-bit DDR (72-bits per cycle) RLDRAM II controllers for external memory accesses (4.8 GBytes/sec.)

What can the FPOA do?

An FPOA can be configured depending on the size of the array, the mixture of Silicon Objects, the arrangement of the Silicon Objects, the amount of memory, and the types of I/O devices. Each family of FPOAs is designed to address a particular application domain and may contain multiple array sizes and object mixes.
