    摘要: A microcomputer system has a peripheral storage control equipped with both a circuit which is responsive to a transfer command received from an MPU to set in a counter a transfer start address, which is designated subsequent to that command. The counter to supply an address for a buffer to control transfer of data from the output of the buffer to a common bus connected between the MPU and a RAM. A circuit is provided for controlling the aforementioned counter to count up in response to a transfer acknowledge signal which is subsequently received from a direct memory access control. In order that the data in the buffer may not be transferred to the RAM but may be rewritten, the peripheral storage control is further equipped with both a circuit for setting a rewrite address also received from the MPU in the counter, which is operative to identify the address of the selected buffer, in association with a rewrite command received from the MPU, and a circuit is also provided for applying the rewrite signal to the buffer each time the rewrite data is received after the setting operation from the MPU.

    摘要: A program executed on a computer including storage, processing, output, and input units, the storage unit storing test-difficulty-calculation-elements-database, test-menu-database, and test-flow-database, for each test-menu-record, the program causing the processing unit to execute: calculating test-difficulty for each test-menu-record based on test-difficulty-calculation-formula by using at least one among pieces of information indicative of relationship with netlist, the number of package/test pins, expected operational clock frequency, process technology information, power consumption, and tester storage space; identifying all relationship between DFT scheme and priority, and causing the storage unit to store information indicative of the relationship between the DFT scheme and priority into the test-flow-database; and sorting the DFT scheme in an order of the priority based on the relationship between the DFT scheme and priority, causing the storage unit to store the DFT scheme as a test flow, and causing the output unit to output the test flow.
