摘要： PURPOSE:To facilitate the debug of software by supplying a single comparison result, a combination of plural comparison results, a single comparison result and its history or a combination of plural comparison results and its histories to a break control circuit. CONSTITUTION:When the break subject is equal to an address, an address ADR showing a break point is set on a comparison register CMP in a chip. When an access occurs, the address to receive an access is compared with the value set on the register and the result of this comparison is supplied to a break control circuit BRCNT. The circuit BRCNT monitors the result of comparison and using combination of the monitor results and the history of the comparison result as inputs to decide whether the designated conditions are satisfied or not, that is, a break is produced or not. Thus the complicated break conditions can be designated.

摘要： PROBLEM TO BE SOLVED: To improve transmission efficiency of downlink data.SOLUTION: This invention relates to a communication method in a radio communication system including at least one base station which has a plurality of transmission parts for communicating with a radio communication terminal and a base station control device for controlling data transmitted from the transmission parts. The base station control device compares the size of the data transmitted from a high-order network and to be transmitted to the radio communication terminal with a predetermined threshold, and selects one of the transmission parts without dividing the data and transmits the data to the selected transmission part when it is determined that the size of the data to be transmitted to the radio communication terminal is smaller than the predetermined threshold. The transmission part transmits the data transmitted from the base station control device to the radio communication terminal.

摘要： PURPOSE:To easily reversely convert the information given to an external part and to obtain internal information by outputting an instructing signal to instruct the access timing to the external part when the converting information is set to a converting table. CONSTITUTION:When a main memory 10 is accessed and converting information is set to an address converting buffer 8, a memory control unit 7 outputs an instructing signal phi to instruct the access timing of the memory 10 to an external part. The signal phi is supplied to an emulator main body 20. The main body 20 stores the address, the data, the signal phi and respective types of control signals into a first trace memory 21A of a trace memory part 21. Further, the information of an address bus AB and a data bus DB is fetched even into a second trace memory 21b. The main body 20 is equipped with an address reverse converting table 22 to convert reversely a physical address to a logical address. The table 22 is used to convert the physical address to the logical address.

摘要： PURPOSE:To fast and surely break a program by using a circuit which switches the SWI instructions held by a memory circuit for input with a signal supplied from outside and performing the replacement of program words. CONSTITUTION:A monitor circuit of a control circuit CONT detects an address where a program to be broken is stored and produces a trigger signal TRG to transmit it to a microprocessor MPU. The MPU switches a multiplexer MPX to the side of a pattern generating circuit PTG when the signal TRG is set at a high level. Thus a program word is replaced with an SWI instruction stored in the circuit PTG and supplied to an FIFO.

摘要： PROBLEM TO BE SOLVED: To realize communication between a base station capable of the communication at a highest transmission rate and a terminal station at all times by securing an incoming communication path between the base station capable of most efficiently transmitting outgoing signals and the terminal station at all times. SOLUTION: Each of terminal stations 111-119 selects the base station capable of receiving outgoing radio waves by the largest reception power and transmit a code for identifying the base station on incoming signals. When the reception power of incoming radio waves transmitted from the terminal station transmitting the code for identifying the present station is larger than a threshold, base stations 501-503 transmit lowering power control signals to the terminal station. In the case that the terminal station transmits the code for identifying other stations or when the reception power of the incoming radio waves transmitted from the terminal station is smaller than the threshold, increasing power control signals are transmitted to the terminal station. The terminal stations each lower transmission power when even one of the power control signals instructing to lower the transmission power is present and increase the transmission power when the power control signals are not present.

摘要： PURPOSE:To provide a trace device which can acquire the bus information in a data access state, the bus information on the program fetch set right before the data access state, and the bus information on the program fetch set right before/after an instruction execution flow is changed. CONSTITUTION:Each of latch circuits 110 and 111 latches the bus information in each instruction fetch cycle and holds the bus information on two bus cycles when the latch operation is exclusively controlled. The exclusive latch operation is started in response to a state where the instruction execution flow detected by a branch signal 205 is changed and also to a data access state which is detected by a program fetch signal 206. Then the bus information latched after the end of the exclusive latch operation are written in a trace memory 100 in parallel to each other.
