Winter 2013

Embedded Processor Interface

•MicroBlaze is the industry-leader in FPGA-based soft processors.•Memory Management Unit (MMU).• 32-bit RISC Harvard architecture soft

processor core.

Winter 2013

MPMC

• Double Data Rate (DDR/DDR2/DDR3/LPDDR) and Single Data Rate (SDR) SDRAM memory support.• Parameterized:• number of ports (1 to 8)• number of data bits to memory (4, 8, 16, 32, 64)• configuration of data path FIFOs.

Winter 2013

NPI PIM Features

• Extends the MPMC capabilities to meet design needs.• Simple interface to memory, can be easily

adapted to nearly any protocol.• Provides address, data, and control signals to

enable read and write requests for memory.• Simultaneous push and pull data from the port

FIFOs.

Winter 2013

NPI Interface State Machine

Winter 2013

Embedded Tri-Mode Ethernet MAC

• Fully integrated 10/100/1000 Mb/s Ethernet MAC.• Configurable full-duplex operation in

10/100/1000 Mb/s.• Media Independent Interface (MII), Gigabit

Media Independent Interface (GMII), and Reduced Gigabit Media Independent Interface (RGMII).
