摘要： Circuitry for providing external access to signals that are internal to an integrated circuit chip package. A plurality of N:1 multiplexers are physically distributed throughout the integrated circuit die. Each of the multiplexers has its N inputs coupled to a nearby set of N nodes within the integrated circuit, and each of the multiplexers is coupled to a source of select information operable to select one node from the set of N nodes for external access. Each of the multiplexers has its output coupled to an externally-accessible chip pad. The integrated circuit is a microprocessor, and the source of select information may include a storage element. If so, additional circuitry is provided for writing data from a register of the microprocessor to the storage element using one or more microprocessor instructions. Each multiplexer may be coupled to a different source of select information, or all multiplexers may be coupled to the same select information. Moreover, a fixed set of interconnect traces may be provided to couple a fixed set of nodes to an additional set of externally-accessible chip pads. One or more M:1 multiplexers may also be provided, having their M inputs coupled to M different outputs of the N:1 multiplexers. Each of the M:1 multiplexers may be coupled to a second source of select information. Preferably, the outputs of the M:1 multiplexers will be coupled to a circuitry for facilitating debug and performance monitoring of the integrated circuit.

摘要： User-configurable diagnostic hardware contained on-chip with a microprocessor for the purpose of debugging and monitoring the performance of the microprocessor. Method for using the same. A programmable state machine is coupled to on-chip and off-chip input sources. The state machine may be programmed to look for signal patterns presented by the input sources, and to respond to the occurrence of a defined pattern (or sequence of defined patterns) by driving certain control information onto a state machine output bus. On-chip devices coupled to the output bus take user-definable actions as dictated by the bus. The input sources include user-configurable comparators located within the functional blocks of the microprocessor. The comparators are coupled to storage elements within the microprocessor, and are configured to monitor nodes to determine whether the state of the nodes matches the data contained in the storage elements. By changing data in the storage elements, the programmer may change the information against which the state of the nodes is compared and also the method by which the comparison is made. The output devices include counters. Counter outputs may be used as state machine inputs, so one event may be defined as a function of a different event having occurred a certain number of times. The output devices also include circuitry for generating internal and external triggers. User-configurable multiplexer circuitry may be used to route user-selectable signals from within the microprocessor to the chip's output pads, and to select various internal signals to be used as state machine inputs.

摘要： Circuitry for detecting signal patterns on a multi-bit bus. First comparison circuitry monitors a first portion of the bus comparing it with a first expected signal pattern, generating a first comparison output. Second comparison circuitry monitors a second portion of the bus comparing it with a second expected signal pattern, generating a second comparison output. Both comparison outputs are applied to an AND gate and a first OR gate. One data input of a multiplexer is coupled to the output of the first OR gate. Another data input is coupled to the output of the AND gate. Another data input is coupled to the first comparison output, and another data input is coupled to the second comparison output.One input of a second OR gate may be coupled to the multiplexer output, and another input coupled to a disable indicator, allowing the multiplexer output to be overridden. The first and second comparison outputs may be generated by bit-wise comparing first and second portions of the bus with first and second expected signal patterns. The logical AND of the respective comparison results may be treated as the first and second comparison outputs, or they may be treated as first and second intermediate bits. These first and second intermediate bits may be ORed with first and second mask bits, and the results may be treated as the first and second comparison outputs. The outputs of the two OR operations may also be EXCLUSIVE ORed with first and second negate bits, respectively.

摘要： A method and apparatus is disclosed for reading data from and writing data to remote registers that are dispersed throughout an integrated circuit chip. Regardless of the size or number of remote registers involved, the operation is accomplished using only two interconnect lines, plus a clock. Each remote register is associated with a unique address. During a write operation, a microprocessor loads the write data into a staging register, loads the destination address into a header generation register along with a read/write control bit, and loads a count value into a clock. Thereafter, the apparatus of the invention proceeds automatically, as the clock counts down, to shift the data onto a serial data line following a header. Each of the remote registers in the system are arranged serially, and each monitors the header information, comparing the address contained in the header with its own address. In the event of a match, the remote register selected is enabled to shift data serially into itself from the serial data line. During a read operation, the selected remote register shifts its data out onto the serial data line. The read data is ultimately shifted back into the staging register.

摘要： In a computing system having a plurality of transaction source nodes issuing transactions into a switching fabric, an underserviced node notifies source nodes in the system that it needs additional system bandwidth to timely complete an ongoing transaction. The notified nodes continue to process already started transactions to completion, but stop the introduction of new traffic into the fabric until such time as the underserviced node indicates that it has progressed to a preselected point.
