Key Points
- Processor in Memory (PIM) architectures for Field-Programmable Gate Arrays (FPGAs) can be advantageous
- PiCaSO II is an overlay architecture that aims to overcome the von Neumann bottleneck by bringing processing closer to data in memory
- The bit-serial Arithmetic Logic Unit (ALU) for FPGA processors includes a Full-ADD/SUB module and an op-code encoder, supporting various operations such as min/max pooling and filter operations
- Different pipeline configurations for PIM-Blocks in FPGA Processor In Memory Architectures (PIMs) are compared, with the Full-Pipe configuration achieving a 2.25x improvement
- PiCaSO-F reduction network provides a 17x improvement in accumulation latency due to the design of the binary-hopping network
