    摘要: Call frame information is used by debugging software. It records how to restore the parent stack frame at any point during execution of a program. It is normally generated during compilation and stored in the executable in a compressed format, consisting of sequences of instructions that describe how the current call frame changes during execution of each function. Described herein is a means of generating call frame information at link time, using linker macro calls generated by a small set of assembler macros.

    摘要: A digital frequency divider includes phase control of the output signal in increments of whole or half cycles of the input frequency. Whole cycle phase control is achieved by varying (logically or physically) the tap off point of a shift register loaded with a bit pattern for appropriate division. Half cycle phase changes is achieved by a multiplexer selecting one of two signals every half cycle.

    摘要: For a packet identification (PID) contained at a variable possible location which comprises part only of a 32-bit packet header, a corresponding DES key value is located. A table (10) stored in memory contains for each DES key (12) (i) a packet header (14) comprising 32 bits with a possible PID of e.g. 12, 9 or 8 bits contained at a defined location and with zero values elsewhere, and (ii) a mask value (16) also comprising 32 bits with ones contained at the said defined location of the PID and zeros elsewhere. The table is divided into regions (18) for respective packet format types. An incoming packet header at an input (22) is combined (26) with a first one of the mask values from the table so as to provide a combined value which consists of the value held in the input packet header at the defined location and zeros elsewhere. This combined value is compared (36) with the corresponding packet header stored in the table. If they are not equal, the combining and comparison is repeated for the next row of the table. If they are equal, the corresponding DES key value is read (32) from the table and provided as an output (38). The system can cope with variable PID formats within the packet header without alteration to the hardware but merely with re-programming of the table contents.

    摘要: A method is described for distinguishing between an input or output signal on a bi-directional pin of a model of a hardware circuit. The method comprises the steps of for a bi-directional pin of said model applying signals to said pin at a reduced drive strength such that a driven signal on said pin will be superimposed over the applied signal, and comparing the drive strength on the bi-directional pin and responsive to said comparison determining whether the bi-directional pin is an input or output.

    摘要: A ratio logic gate has a current mirror (20) controlled by the pull-down transistors (10-13) and supplying a half size pull-down transistor (23). When one or more of the input pull-down transistors (10-13) is on, the mirror current overcomes the output pull-down transistor (23) to provide a high potential output. Process tolerances between p and n type devices is thus avoided.
