Sustainability is a big buzzword in modern architecture – and not just when building the world’s tallest wooden skyscraper. According to the Green Building Council – an authority on sustainable buildings and communities in Australia – the built environment accounts for nearly 40% of “global energy related carbon emissions,” with materials and construction alone accounting for 11% of that global total. But once a recently approved residential high-rise in Perth, Australia, is erected, there will be no mistaking how central sustainability was to the project. Why? Because it would stand as the tallest wooden skyscraper in the world.

Envisioned by an Australian architecture firm, C6 (the project’s name, which is derived from its location at 6 Charles Street) aims to incorporate hybridized timber not just for floor paneling, but as an essential structural element throughout all of its 50 stories, making up a substantial amount of the project’s total materials. As a result, the architecture firm claims that C6 will use “around 45% less concrete than a traditional building of a similar scale”.

There’s no timeline for the completion of C6 just yet. But don’t be surprised if this landmark inspires other sustainable-minded architects to eclipse its benchmark by the time residents are moving in.

Bus Interface Unit (BIU)

The BIU contains a prefetch queue, a bus controller, segment registers, and the instructions pointer (IP). The main purpose of the BIU are to keep the prefetch queue filled with instructions, to generate and accept the system control signals, to provide the system with a memory address or input/ output (I/O) port number, and to act as a window between the EU and memory for data.

The BIU ensures that the queue is filled with instructions by fetching the next single byte of an instruction if the 8088 queue has space, and two bytes if the 8086 queue has space. Prefetching allows the execution unit to obtain the next instruction directly from the BIU instead of the memory as required by older, 8-bit microprocessors. Because the next instruction is already inside of the 8086/8088 when execution is imminent, the microprocessor executes software at a much higher speed than if every instruction were fetched directly form the memory.
