摘要： Systems and methods are disclosed herein for retrieving data from memory in a computer system. In one example, a memory controller is coupled to a system bus in a computer system that includes bus masters similarly coupled to the system bus. The memory controller is configured to receive requests to read or write data from memory from bus masters of the computer system. If the memory controller receives an initial request from certain bus masters, the memory controller is further configured to anticipate a future request from certain bus masters and prefetch data on behalf of certain bus masters for rapid delivery following a subsequent request to read data from memory submitted by the certain bus masters.

摘要： A cache memory is disclosed with reduced tag array searches for sequential memory accesses. The cache memory has components such as at least one tag array, at least one data array associated with the tag array, a tag read control logic module for controlling a tag array search, a comparator associated with the tag array, and a storage module for storing a match result of the comparator while processing a first memory access request that accesses a first data address in a first cacheline of the data array. The stored match result is used for a second memory access request that intends to access a second data address sequential to the first data address, thereby avoiding searching the tag array for the second memory access request.

摘要： A system for allowing an asynchronous clock signal to be selected from a plurality of asynchronous clock signals without causing glitches. In the system, a requestor is connected to control signals. The control signals indicate to the requestor which asynchronous clock signal, of the two or more clock signals, to request. The requestor informs a selector of the request. The selector determines which asynchronous clock signal was selected. The selected asynchronous clock is then detected by the detector. The detector feeds the selected asynchronous clock signal to a signal output. The signal output releases the selected asynchronous clock signal.

摘要： A processor includes a translation lookaside buffer (TLB) including a data array and a compare unit. The data array includes a number of entries each configured to store a respective translated physical address. In response to a read access to a given entry of the TLB, the data array is configured to output within a particular clock cycle, the respective translated physical address stored in the given entry. In addition the compare unit may be configured to compare the respective translated physical address output by the data array with a number of additional addresses. The compare unit may also be configured to provide a hit indication for each of the additional addresses within the particular clock cycle.

摘要： A dual port memory includes a mechanism for preventing collisions. The memory includes dual port bit cells arranged in rows and columns and each bit cell stores a data bit. The memory also includes a wordline unit that may provide a respective write wordline signal and a respective read wordline signal to each row of bit cells. The wordline unit may also selectively inhibit the read wordline signal for a given row based upon address information that is indicative of whether a write operation will be performed to the given row.

摘要： Systems and methods are disclosed for locking code in cache. A processor comprises a cache and a cache controller. The cache is configured to store a temporary copy of code residing in main memory. Also, the cache is divided into a number of cache ways, where each cache way is further divided into a number of cache way portions. The cache controller is configured to utilize a first signal and a second signal. The first signal designates one of the cache ways as a partial cache way and the second signal defines which ones of the cache way portions of the partial cache way are to be locked.

摘要： Systems and methods for detecting a leading edge of a bus clock signal are disclosed herein. One edge detecting system includes a device for providing a bus clock and a processor clock, in which the processor clock is an integer multiple of the bus clock. The device for providing the clocks, however, does not provide a control signal that indicates the location of an edge of the bus clock. The system further includes a clock tree configured to distribute the bus clock and processor clock to multiple destinations, whereby the destinations receive the bus clock and processor clock delayed by an insertion time of the clock tree. The system also includes a processor having a device for detecting the leading edge of the bus clock delayed by the insertion time. Furthermore, a method is disclosed herein. The method includes generating a bus clock and a processor clock without a corresponding control signal, receiving an insertion-delayed version of the bus clock and processor clock, and processing the insertion-delayed bus clock and processor clock to generate a flag signal that indicates the location of a leading edge of the insertion-delayed bus clock.
