Introduction to Computer Architectures 1 Answers ICAR Laboratory : PicoBlaze Lab 5 Task 1 Q: If each instruction takes two cycles to execute the time to process this data is given by: Processing time = Number of Instructions × 2 × Clock period If the typical clock speed for the PicoBlaze processor is 50MHz how long will it take to execute this program? A: IC = 3 + 11×16 + 1 = 180 Processing time = 180 × 2 × 20ns = 0.0000072 = 7.2us Note, the processor's clock speed will be different for each system, determined by the hardware architecture i.e. the critical path delay, and the technologies used to implement it i.e. the switching speed of the transistors used.

Introduction to Computer Architectures 2 Task 4 PicoBlaze_VHDL_MISD.zip device utilization summary (baseline used later) o Number of Slices: 142 o Number of FF : 114 o Minimum period: 107MHz Owing to how the hardware is implemented in the FPGA i.e. the fundamental building blocks (slices) contain spare ‘functionality’ therefore, only 1 ‘additional’ hardware is required to implement the pipeline architecture.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
