AT94 Training 2001Slide 9 AT40K Key Features DSP Atmel Features: Core cell ‘up-stream’ AND gate give 1 multiplier ‘tile’ per core cell. Diagonal and Orthogonal core cell connection mean no bussing resource consumed to make array multiplier AT40K 4 X 4 array multiplier 16 core cells Xilinx 4K series requires 12 CLBs to create a 4 x 4 array multiplier. Each CLB is equivalent to 2 Atmel core cells which means a Xilinx 4 x 4 array multiplier is equivalent to 24 Atmel core cells. Xilinx does not have diagonal direct connects so they also consume a large number of bus resources to do multiplier. CLB cell Atmel Diagonal direct connection Xilinx need two buses to make a Diagonal

AT94 Training 2001Slide 11 AT40K Key Features FreeRAM Atmel Features: Distributed SRAM “FreeRAM” Fast 10ns access time Fully Programmable Single or Dual port Synch or Async Using RAM does not use core cells Xilinx 4K series has 16 x 1 Dual port Ram in each CLB 32 x 4 Dual port RAM is 8 CLBs and each Xilinx CLB is 2 X an Atmel core cell. A Xilinx 32 X 4 Dual port RAM consumes the equivalent of 16 Atmel core cells !!!! With AT40K the RAM is FREE 32x 4 bits of Dual port RAM
