NMPSM3軟處理器

NMPSM3概述
在UCSC擴展學(xué)院上了第一門FPGA課后，我對這些設(shè)備為普通人提供的功能感到驚訝，我決定更深入地研究它們。我最終意識到我有足夠的邏輯設(shè)計知識，可以構(gòu)建自己的簡單處理器。在了解了KCPSM（nanoblaze）之后，我開始構(gòu)建自己的處理器，并將其稱為NMPSM（Nick Mikstas可編程狀態(tài)機）。我花了三遍迭代才能制作出功能全面的處理器，因此命名為NMPSM3。即使NMPSM3受到nanoblaze IO方案的啟發(fā)，其內(nèi)部結(jié)構(gòu)也完全不同。NMPSM3是具有四個獨立中斷和一個復(fù)位的16位處理器。NMPSM至少需要實現(xiàn)四個18Kb BRAMS：一個用于寄存器，一個用于堆棧，一個用于解碼器，至少一個用于程序ROM。使處理器正常工作后，我為其編寫了匯編程序，并創(chuàng)建了一個大型項目以展示其功能。
本文引用地址：http://www.ex-cimer.com/article/202409/463060.htm當(dāng)我第一次設(shè)計NMPSM3時，它是在Digilent Nexys 2板上實現(xiàn)的。Nexys 2上有Xilinx Spartan 3部件。在成功實施該項目之后，幾年來我對NMPSM3一無所獲。我最終在SCU上了一門課，基本上和UCSC Extension上的一門課一樣。我決定通過更新項目以使其在Digilent Basys 3 FPGA板上工作來使NMPSM3振作起來。由于新的FPGA部件（Artyx 7）比Spartan 3具有更多的功能，因此我也對該項目進行了一些升級。我也寫了一份詳盡的報告。

與處理器一起，我還基于8位Nintendo構(gòu)建了其他一些模塊，包括UART和圖片處理單元（PPU）。一些Verilog代碼很粗糙，因為在創(chuàng)建此項目時我正在學(xué)習(xí)Verilog。
