System Partitioning Microelectronic systems typically consist of many functional blocks. If a functional block is too large to fit in one ASIC, we may have to split, or partition, the function into pieces using goals and objectives that we need to specify. For example, we might want to minimize the number of pins for each ASIC to minimize package cost. We can use CAD tools to help us with this type of system partitioning. Figure 15.2 shows the system diagram of the Sun Microsystems SPARCstation 1. The system is partitioned as follows; the numbers refer to the labels in Figure 15.2 . (See Section 1.3, “Case Study” for the sources of infomation in this section.) Nine custom ASICs (1–9) Memory subsystems (SIMMs, single-in-line memory modules): CPU cache (10), RAM (11), memory cache (12, 13) Six ASSPs (application-specific standard products) for I/O (14–19) An ASSP for time of day (20) An EPROM (21) Video memory subsystem (22) One analog/digital ASSP DAC (digital-to-analog converter) (23) Table 15.1 shows the details of the nine custom ASICs used in the SPARCstation 1.

    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.
