Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] The present invention designs an expansion board with an FMC interface, on which a plurality of PCMs are placed, aiming to control access to the PCM after the expansion board is connected to the FMC slot, and to implement some feasible PCM application schemes.

[0051] FMC (FPGA Mezzanine Card) FPGA mezzanine card is a standard developed by an alliance of companies including FPGA manufacturers and end users. It belongs to the ANSI standard and aims to provide standard mezzanine card sizes, connectors and modules for FPGAs on basic boards. interface. The FMC standard supports a large number of existing industry-standard board sizes, including VME, CompactPCI, VXS, VPX-REDI, CompactPCI Express, AdvancedTCA, and AMC.

[0052] The PCM FMC expansion board has 5 built-in PCMs, 4 of which are interconnected by SPI serial interface, and 1 is connected b...

Abstract

The invention discloses a PCM FMC expansion board based on Zynq-7000 and a working method of the PCM FMC expansion board. The PCM FMC expansion board comprises Zedboard development board based on Zynq-7000 and a PCM FMC expansion board body. The PCM FMC expansion board is characterized in that a plurality of PCMs a built in an FMC board, parts of the PCMs are connected to an FMC interface through SPI serial interfaces, and the other parts of PCMs are connected to the FMC interface through parallel interfaces. The Zedboard development board is characterized in that the Processing System of a dual-core ARM Cortex-A9 processor and Xilinx Programmable Logic are integrated in a single chip. The PCM FMC expansion board has the advantages that the PCM FMC expansion board can provide complex control ability of ARM and high-speed concurrent processing ability of FPGA.

Description

technical field [0001] The invention relates to a Zynq-7000-based PCM FMC expansion board and a working method thereof. Background technique [0002] Phase change memory, referred to as PCM, is a storage medium that utilizes the huge conductivity difference between the crystalline and amorphous states of chalcogenides to store data. As an emerging storage medium, PCM has the following main features: [0003] (1) Non-volatile. Data is stored in the form of phase change in PCM, unless subjected to high temperature exceeding the crystallization temperature, the data will be destroyed. PCM does not need to worry about data loss due to power failure, nor does it need to consider data loss due to unexpected events such as falling. [0004] (2) One bit is variable. Like RAM, the smallest variable unit of PCM is one bit. Flash requires a separate erasing step when changing the stored information, while PCM does not need an erasing step, and can directly change from 0 to 1 or fr...
