摘要： A cache memory device comprises a data cache memory, an instruction cache memory, an instruction code area change detector, and an instruction code change processor. The instruction code area change detector decides whether writing access to the data cache memory by the processor is to a data area or to an instruction area of a main memory. The instruction code change processor passes the data cache memory to perform direct writing into the main memory when the writing access is to the instruction area, and, when data for a processor address is cached in a tag section of the instruction cache memory, invalidates the effective flag of the tag section.

摘要： Each register of an internal register unit of a microprocessor has a pair of register cells consisting of first and second cells having the same register address. When one of these cells is selected, the other cell non-selected serves as a "back-up cell" for the selected cell. Each register of the register unit has a flag bit for storing a selector flag representing which cell of the pair of cells of the register is currently selected, and a flag bit for storing a change flag representing whether register information of the register is rewritten after a selected cell is changed between the first and second cells of the register. When the register information is stored in one of the pair of cells currently being selected of a certain register and is to be rewritten with another new information, the other cell of the register is selected to store the new information therein. The original register information is held in the first cell, thereby eliminating necessity of saving the original register information to a main memory at this stage. When the original register information is required again, the original register information can be rapidly restored, by only selecting the first cell again, in the corresponding register without executing save/restore processing between the register unit and the main memory.

摘要： A register device includes a register set group, a switching control unit, a write control unit, a write flag memory unit, and a read control unit. The register set group consists of a plurality of register sets each constituted by a plurality of registers. The switching control unit selects a register set to be used in processing from the register set group in response to a saving/recovery instruction. The write control unit writes data in registers of the register set selected by the switching control unit in response to a write instruction. A write flag representing whether data is written in each of the registers is held by the write flag memory unit. The read control unit determines, in response to a read instruction, a register in which data is written most recently of a plurality of registers corresponding to each other between the register sets with reference to the write flags, thereby reading out data from the register.

摘要： A copy-back type cache memory device using a delayed wait method capable of completing a data-write process in one process cycle. The device includes single word memory means for storing the single word of the selected data in a data memory means when an access for a data-write is made, the single word being located at the address in the data memory means corresponding to the processor address; and copy-back memory means for restoring the superseded data along with other data together with which the superseded data forms a block, so that the block can be reorganized in its original state before the data-write process takes place. The device may alternatively include an address latch means for delaying transmission of a processor address from the processor to the data memory means by a predetermined number of process cycles when access by the processor is for a data-write process; and a data latch means for delaying transmission of a processor data from the processor to the data memory means by the predetermined number of process cycles when access by the processor is for a data-write process.

摘要： A presentation display apparatus including a data storage section for storing a plurality of explanative image data each having (R), (G) and (B) color image components, a data processing section for adding, to the explanative image data from the data storage section, function select image data different in color component from the explanative image data, an image memory for storing the image data of one screen image output from the data processing section, a listener's first display device for displaying the image data which is delivered from image memory and a speaker's second display device. The image data output from the image memory is supplied through a first color converter to the listener's display device and through a second color converter to the speaker's display device. In the first color converter, the explanative image data is alone directly delivered as conversion image data in spite of function select menu image data, so that only the explanative (R)/(G)/(B) image is displayed on the listener's display device. In the second converter, the (R)/(G)/(B) input data are directly output as conversion image data when the function select image data is "0" and otherwise converted to all "1" when the function select menu image is "1" so that the function select menu and (R)/(G)/(B) explanative image are overlappingly displayed on the second display device.

摘要： An instruction cache and a data cache are formed with a 2-port structure, the first port of the instruction cache is exclusively used for readout of the contiguous instruction, and the second port thereof is exclusively used for readout of the branched instruction when the conditional branch instruction is executed. With this construction, two instructions which may be executed can be simultaneously fetched irrespective of whether the branch of the conditional branch instruction is taken or untaken, thereby making it possible to enhance the CPU performance. Further, in the 2-port data cache, time for the cache refill process can be reduced by means of the contiguous data transfer and non-cacheable access.

摘要： A bus bridge mutually connects a CPU bus to which a CPU and a corresponding cache memory having a write-back scheme are coupled, an I/O bus to which a bus master is coupled, and a main memory which is commonly accessed through the CPU bus or I/O bus. In response to an access request from the bus master to the main memory, a cache snooping section snoops a cache memory to see whether an address in the access request satisfies a cache hit or miss, and data corresponding to the address is dirty or clear. In response to a snooping result by the cache snooping section indicating that the cache hit has occurred and the data is dirty, a write-back control section writes back the data from the cache memory in the main memory. In the case where the access request indicates a read request, a data bypass section directly transfers the data from the cache memory onto the I/O bus while the write-back control section performs writing back. With this processing, data read processing from the main memory need not wait for completion of write-back processing with respect to the main memory. Therefore, even if a cache write-back operation is performed in response to a main memory access request from the bus master, the main memory access operation can be performed at a high speed.
