Using Logisim Evolution, I continue testing out the Hack CPU described in chapter 5 of The Elements of Computing Systems. I use the second test program in the chapter, Max.hack. This tests a few of the conditional comparisons/jump instructions. I show the binary of the program, disassemble it, load it into ROM, and demonstrate the CPU execute the program properly. I assume you have read chapter 4 of the book which covers the machine language of the Hack platform.

This is the fifth video in a sub-series on building a VGA interface for the HackCPU computer using Logisim Evolution. I build a pixel generator which fetches bits from RAM and displays them to a VGA monitor, in preparation to put the VGA interface under Hack computer control. I demonstrate a test circuit connected to ROM running on a Digilent CMOD A7. The first VGA intro video of the series is: https://www.youtube.com/watch?v=w4vrNSY9cxY The second VGA video of the series that describe construction of the sync pulse generator is: https://youtu.be/w4vrNSY9cxY The third VGA video of the series describes the porch and margin generator is: https://youtu.be/Z4Ph6Jo67Y0 Resources: https://github.com/logisim-evolution/logisim-evolution#download https://mitpress.mit.edu/9780262539807/the-elements-of-computing-systems/ https://tomverbeure.github.io/video_timings_calculator https://digilent.com/shop/cmod-a7-35t-breadboardable-artix-7-fpga-module/ https://digilent.com/shop/software/digilent-adept/ https://www.amazon.com/gp/product/B08FYPTWDQ/ref=ppx_yo_dt_b_asin_title_o09_s03?ie=UTF8&psc=1 You will need the develop branch from Logisim Evolution in order to pick up the board design for the CMOD A7, as well as obtain the clock synthesis feature I added to Logisim, until such time as my changes make it into a Logisim release.

Logisim circuit file of keyboard circuit for Hack computer.

This is the fourth video in a sub-series on building a VGA interface for the HackCPU computer using Logisim Evolution. I discuss the schematic and electrical theory behind creating it and use a test pattern component to demonstrate the driver interface working on a VGA monitor. I demonstrate the circuit running on a Digilent CMOD A7.
