摘要： A dual port RAM includes an any-time readable/writable memory block in which an access can be made to the same storage area from independent first and second ports. In addition, the RAM includes a first test circuit for performing a test to the storage area of the memory block via the first port on the basis of a first clock signal, and a second test circuit for performing a test to the storage area of the memory block via the second port on the basis of a second clock signal. A control circuit of the RAM causes the first and second test circuits to test the memory block in an alternating manner.

摘要： A digital signal processor includes a programmable memory, a processor and an access controller. The programmable memory has blocks each of which is capable of reading and writing an instruction of a program. The processor sequentially executes the instruction stored in the programmable memory. The access controller sequentially stores the instruction of the program in the blocks of the programmable memory on the basis of an address indicating a location of the respective blocks where the instruction is stored. The access controller controls an access of the processor to the respective blocks.

摘要： There is provided a control system for an internal combustion engine, which is capable of matching an output torque of the engine with a demanded torque excellently when the combustion mode is switched, thereby enhancing drivability. A demanded fuel amount and a demanded torque of the engine are calculated according to detected operating conditions of the engine. A combustion mode is determined to be either the stratified combustion mode or the homogeneous combustion mode according to the demanded torque. A pre-switching demanded fuel injection time period and a pre-switching demanded torque are stored. When the combustion mode is switched, a switching-time demanded fuel amount (limit value) is calculated according to the stored pre-switching demanded fuel injection time period and pre-switching demanded torque, the current demanded torque, and an estimated combustion efficiency parameter.
