摘要： A bridge interface for buses in a computer system has a direct memory access (DMA) controller that controls memory transfers in the computer system. The DMA controller has a pair of cascaded DMA controller chips that provide a plurality of DMA channels. A multiplexer circuit receives memory address signals from the DMA controller chips. The memory address signals are received in both a shifted form and an unshifted form at the multiplexer inputs. By selection of the shifted or the unshifted memory address at the multiplexer, either even or odd addresses are produced at the multiplexer output for each DMA channel, thereby selectively providing 8-bit or 16-bit memory accesses. The control of the multiplexer is programmable for each DMA channel, providing dynamic configuration of the DHA channels as either 8-bit or 16-bit channels.

摘要： A data processing system includes a memory controller for accessing a dynamic memory having a plurality of SIMMs (Single In-line Memory Modules) that differ in size and speed of operation. The memory controller is operable, in response to an access request for a given SIMM, to read from a SIMM definition register and dynamically produce memory access signals in accordance with the timing requirements of the particular SIMM being accessed. Such signals are set each time a SIMM is accessed. The signals provide different clock periods of RAS precharge time, RAS (Row Address Strobe) to CAS (Column Address Strobe) time, and CAS pulse width, depending on the SIMM being accessed.

摘要： A direct memory access (DMA) support mechanism is provided for use in a computer system which comprises (i) a central processing unit (CPU) connected to system memory by a first system bus, and a second system bus connected to the CPU; (ii) a host bridge connecting the second system bus to a peripheral bus; (iii) an input/output (I/O) bridge connecting the peripheral bus to a standard I/O bus, the standard I/O bus having a plurality of standard I/O devices attached thereto; and (v) arbitration logic which functions in an arbitration mode for arbitrating between the plurality of standard I/O devices competing for access to the standard I/O bus, and in a grant mode wherein a selected standard I/O device is granted access to the standard I/O bus. The DMA support mechanism comprises a direct memory access (DMA) controller for performing DMA cycles on behalf of the selected standard I/O device, and direct memory access (DMA) support logic for enabling the DMA cycles to be performed over the peripheral bus. The DMA support logic includes sideband signals directly connecting the DMA controller with the I/O bridge, the sideband signals including information identifying the bus size of the selected I/O device for which the DMA controller is performing the DMA cycles.

摘要： A dual bus microcomputer system including a cache subsystem improves performance under certain circumstances by allowing programmable control over the LOCK function. More particularly, additional logic is coupled between the LOCK output of the CPU and the LOCK input of the cache controller. A control bit from an I/O port is a second input to the additional logic. With the control bit in one state, the logic allows the LOCK input to follow the LOCK output. In the other state of the control bit, the LOCK input is disabled regardless of the state of the LOCK output.

摘要： A microprocessor system employing an 80386 CPU and an 82385 cache controller has the capability of functioning with dynamic bus sizing (where the CPU interacts with devices which may or may not be 32-bits wide), as well as posted write capability. Unfortunately, the two capabilities have the possibility of an incompatibility if a write cycle is posted to a device which cannot transfer 32 bits on a single cycle. The present invention provides logic to overcome this incompatibility. An address decoder is provided to decode the tag portion of an address asserted on a CPU bus to determine if the asserted address is inside or outside a range of addresses which define cacheable devices. Any cacheable device is by definition 32 bits wide and therefore posted writes are allowed only to cacheable devices. Accordingly, the microcomputer system employing the invention posts write cycles to cacheable devices; write cycles to non-cacheable devices are inhibited from being posted.
摘要翻译：采用80386 CPU和82385高速缓存控制器的微处理器系统具有动态总线大小调整功能（CPU与可能或不是32位宽的设备交互）以及发布的写入功能。不幸的是，如果将写周期发布到在单个周期内不能传输32位的器件，则这两个功能具有不兼容的可能性。本发明提供了克服这种不兼容性的逻辑。提供地址解码器来解码在CPU总线上断言的地址的标签部分，以确定所断言的地址是否在限定可高速缓存设备的地址范围之内或之外。任何可缓存设备的定义为32位宽，因此发布的写入仅允许可缓存设备。因此，采用本发明的微计算机系统将写入周期写入可高速缓存的设备; 对不可缓存设备的写周期被禁止发布。
