摘要： A microprocessor (5) including a plurality of write buffers (30) of varying sizes is disclosed. The varying sizes of the write buffers (30) allow for each write transaction from the core of the microprocessor (5) to be assigned to the most efficient write buffer size. Each write buffer (30) also includes sequential control logic (50) that issues a status code indicating the extent to which its write buffer (30) is filled; the control logic (50) advances to a more full state responsive to receiving a new data transaction from the internal bus, and advances to a more empty state responsive to completing a write transaction to the external bus. Each write buffer (30) communicates data from an internal bus (PBUS) to an external bus (BBUS) in a manner that is synchronized in the control path, rather than in the data path. Clock domain translation circuitry (65) is included within timing control circuitry (62) to translate the control signal from one clock domain to another, thus ensuring that overlapping writes do not occur. Internal snoop control circuitry (71) is also provided, for controlling access to the write buffers (30) so that memory reads missing in on-chip cache may be performed to the write buffers (30), rather than to main memory (21), if the data remains resident therein. A read buffer (33) is also disclosed, and has a plurality of entries for receiving blocks of data from the external bus (BBUS); upon receipt of a block of data, the read buffer (33) indicates the presence of data therein to the core of the microprocessor (5) to initiate its retrieval for execution of an instruction.

摘要： A microprocessor (5) including a clock domain translation circuit (50a) for communicating a digital signal from a high speed clock domain to a low speed clock domain is disclosed. The disclosed microprocessor (5) includes clock generation circuitry (20) which generates internal and bus clocks at different multiples of a system clock signal. The clock generation circuitry (20) includes a counter (60) that indicates, for a given frequency ratio, signals (REGION) indicating the current phase region of the faster clock (PCLK) relative to the slower clock (BCLK). The clock domain translation circuit (50a) includes a series of input registers (82, 84) in sequence, with the output of each as well as the input signal line (IN PCLK) coupled to inputs of a multiplexer (80). The multiplexer (80) selects either the input signal directly or the output of one of the registers for application to an output register (90), clocked by the slower clock signal (BCLK), depending upon the phase region of the faster clock (PCLK) relative to the slower clock (BCLK) for communication of that signal. As a result, the input digital signal is held for enough time to be properly clocked in, depending upon the phase region, thus enabling frequency ratios of non-integer values to be utilized in system operation.

摘要： The present invention provides a method for transferring groups of data between a microprocessor cache memory (114) and an external memory (105) across a data bus (Bbus). Each group of data includes as many bits of data as the width of the bus (Bubs) with the total amount of data transferred filling a line in the cache memory (114). The bus interface unit (112) of the microprocessor (110) initiates a burst read by starting a read request, asserting the address strobe bit and sending the initial requested address on the external bus address bits of the microprocessor (110). The external system will then respond by asserting a burst ready signal, followed by the data bits residing in the appropriate address position. The particular addresses for this data is selected according to the current burst mode, which may be high performance, low power or compatible with a previously known burst mode. Subsequent groups of data are then sent in subsequent cycles according to the prescribed order of the burst mode up to n (=B/b) transfers. In a high performance mode the first group of bytes requested are always returned first. The next transfer will supply the necessary data that will satisfy the next level of data size hierarchy. Thereafter, transfer order follows an increasing wrap-around order. A low power mode includes an initial data order similar to the high performance mode with the additional limitation that only one address bit changes for each sequential data group. A burst write is performed similarly.
