The ATI Mach line was a series of 2D graphics accelerators for personal computers developed by ATI Technologies. It became an extension (and eventual successor) to the ATI Wonder series of cards. The first chip in the series was the ATI Mach8.[1] It was essentially a clone of the IBM 8514/A[2] with a few notable extensions such as Crystal fonts. Being one of the first graphics accelerator chips on the market, the Mach8 did not have an integrated VGA core. In order to use the first Mach8 coprocessor cards, a separate VGA card was required. This increased the cost of ownership as one had to purchase two rather than one expansion card for graphics. A temporary solution was presented with the ATI Graphics Ultra/Vantage cards, which combined an ATI 8514 Ultra and VGA Wonder+ into a single card (though using discrete ICs). The Mach32 chip was the follow-up to the Mach8, which finally featured an integrated VGA core, true colour support and a 64-bit datapath to internal memory.

A data path is a collection of functional units such as arithmetic logic units (ALUs) or multipliers that perform data processing operations, registers, and buses. Along with the control unit it composes the central processing unit (CPU). A larger data path can be made by joining multiple data paths using multiplexers. A data path is the ALU, the set of registers, and the CPU's internal bus(es) that allow data to flow between them. The simplest design for a CPU uses one common internal bus. Efficient addition requires a slightly more complicated three-internal-bus structure. Many relatively simple CPUs have a 2-read, 1-write register file connected to the 2 inputs and 1 output of the ALU. During the late 1990s, there was growing research in the area of reconfigurable data paths—data paths that may be re-purposed at run-time using programmable fabric—as such designs may allow for more efficient processing as well as substantial power savings.
A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and although popular in the 1970s and 1980s, more modern computers use a variety of separate buses adapted to more specific needs. The system level bus (as distinct from a CPU's internal datapath busses) connects the CPU to memory and I/O devices. Typically a system level bus is designed for use as a backplane.
A data processing unit (DPU) is a programmable computer processor that tightly integrates a general-purpose CPU with network interface hardware. They are also occasionally called "IPUs" (infrastructure processing unit) or "SmartNICs". They can be used in place of traditional NICs to relieve the main CPU of complex networking responsibilities and other "infrastructural" duties; although their features vary, they may be used to perform encryption/decryption, serve as a firewall, handle TCP/IP, process HTTP requests, or even function as a hypervisor or storage controller. These devices can be attractive to cloud computing providers whose servers might otherwise spend a significant amount of CPU time on these tasks, cutting into the cycles they can provide to guests. They see use in other kinds of data center environments as well due to their improved power consumption efficiency for routine networking tasks compared to general-purpose CPUs. Modern DPUs may integrate an operating-system-capable general-purpose CPU with DRAM and storage directly into a high-speed NIC datapath. Such devices can provide network throughput in the 100–400 Gbit/s range, although their CPU cores are generally less powerful than those of the host processor.

Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
