摘要： In a computer system having multiple components, a bidirectional scheme which allows bidirectional data communications between components over a single wire without using termination resistors by placing two drivers from two corresponding processor cores on the same wire, and allowing simultaneous data transfer in two directions. This doubles the effective bandwidth per pin without requiring a modification to the clocking scheme of the system. The driver is impedance matched to the line, and used as the termination for the driver on the opposite end of the wire. This reduces the termination power, since no power is consumed when both drivers are in the same state. The bidirectional flow of data creates a ternary encoding, with a relatively simple decoding possible.

摘要： An arbiter provides at an output a priority signal that indicates which one of the input signals at an input has gained priority over all other ones. The arbiter comprises a signal processing path between the input and the output for determining the priority signal. The arbiter further comprises a control means coupled to the signal path for detecting (rare) conflicts among priority candidates. In response to the detected conflict, the control means generates control signals to modify the signal path. This conflict-solving part of the arbiter is located outside the signal path. Accordingly, a signal propagation delay in the path is largely independent of the number of input signals.

摘要： A data transfer system includes a buffer for storing data to be transferred out of the buffer and a register circuit coupled to the buffer for receiving the data from the buffer. The buffer generates a first indication signal when the buffer is almost empty. The buffer generates a second indication signal when the buffer is empty. The register circuit generates a request signal to receive the data from the buffer. The data transfer system further includes a throttling circuit coupled to the buffer and the register circuit for throttling data transmission to the register circuit from the buffer when the buffer generates the first indication signal and for stopping data transmission to the register circuit from the buffer when the buffer generates the second indication signal. The throttling circuit receives the first and second indication signals and the request signal. The throttling circuit maintains maximized data transfer rate between the buffer and the register circuit while immediately stopping the data transfer between the buffer and register circuit when the buffer is empty.

摘要： An arbiter based on pairwise mutual exclusion produces an absolute priority signal (G) indicating that one of three or more requests (R.sub.1, R.sub.2, . . . R.sub.N) has gained absolute priority over all the other. At least one mutual-exclusion element (20.sub.1 or 20p) in the arbiter is designed so that its pairwise priority determination car be reversed in response to at least one externally originated test signal (T.sub.1, T.sub.2 or T.sub.M-1, T.sub.M). By doing so after the requests have been asserted in a specified order, a priority conflict can be generated among the requests in order to check the conflict-resolution capability of the arbiter.

摘要： A device and method for improving the synchronization and metastability resolving capabilities of a flip flop. At least one master latch resolves a metastable condition of a received data signal thereby generating a stable data signal which is received and then displayed by a slave latch. Latches with superior metastability time resolution are configured in a master-slave relationship along with a novel clocking scheme whereby the clock signal supplied to the master latch is inverted as compared to that which is supplied to slave latch. As a result, the input data is latched on a falling edge of a clock signal and subsequently displayed on the rising edge of the clock signal providing at one half cycle for the input data to settle before passing out the data thereby allowing metastabilities to resolve during that period.

摘要： A multiple-input arbiter first mutually correlates groups of input signals for identifying a particular group, which includes at least one input signal that is a candidate for gaining the overall priority. Thereupon the priority winner is determined in that particular group. Such a hierarchical processing lends itself to an architecture wherein the processing in groups is implemented by cascaded levels of uniform logic blocks. The decomposition in uniform logic blocks considerably simplifies the design of arbiters that process large numbers of input signals.
