摘要： A data processing address generator includes a plurality of address registers, a plurality of index address registers, a modulo register storing a plurality of carry break indicators and an arithmetic unit. The arithmetic unit adds or subtracts a selected address register and a selected index register. The arithmetic unit generates a normal carry between a particular bit and the next more significant bit if a corresponding carry break indicator stored in said modulo register has a first digital state. The arithmetic unit breaks any carry between the particular bit and the next more significant bit if the corresponding carry break indicator has a second digital state. The carry break may be dependent upon a modulo qualifier bit being in an enabling state. The modulo qualifier bit may be stored in one of a plurality of qualifier registers corresponding to the address registers.

摘要： A multi-processor system and method arranged, in one embodiment, as an image and graphics processor. The multiprocessor system includes several individual processors all having communication links to several memories. Additional instruction memories are dedicated individually as cache memories to particular processors so that the processors can function in the multiple instruction, multiple data (MIMD) mode. When the processors function in the single instruction, multiple data mode (SIMD) the dedicated memories are reassigned for access by all of the processors for data. A crossbar switch serves to establish the processor memory links. The entire image processor, including the individual processors, the crossbar switch and the memories, is contained on a single silicon chip.

摘要： A data processing apparatus includes an arithmetic logic unit is divided into a plurality of sections. Each section generates at a corresponding output a digital resultant signal representing a combination of respective subsets of first and second multibit digital inputs. The arithmetic logic unit includes a status detector generating a single bit status signal indicative of said digital resultant signal of a corresponding section of the arithmetic logic unit. These single bit status signals are stored in predetermined locations within a multiple flags register. An options register stores an indication of the number of sections selected from a plurality of possible number of sections into which the arithmetic logic unit is divided. The arithmetic logic unit is further connected to the multiple flags register so that each section selects for output either corresponding bits of the first multibit digital input or the second multibit digital input dependent upon the digital state of a corresponding single status bit in the multiple flags register. This technique permits a variety of functions such as add with saturation, maximum, pixel transparency and color expansion.

摘要： This invention is a manner of control of the addresses of memory accesses. The data processing device of this invention includes a memory, a control circuit, a guide table and an address generating circuit. The control circuit receives a packet transfer request and packet transfer parameters. The packet transfer parameters include a start address, a number of guide table entries and a table pointer. The guide table includes guide table entries, each guide table entry having an address value and dimension values defining a block of addresses. The table pointer initially points to a first guide table entry in the guide table. The address generating circuit forms a set of block of addresses for memory access corresponding to each guide table entry, having a start address from a predetermined combination of the start address and the address value of the guide table entry. The block of addresses are formed from the dimension values. Following the memory accesses, the address generating circuit updates the table pointer to point to a next entry in the guide table. The address generating circuit may optionally form the predetermined combination of starting address and address value of guide table entry by adding the address value to the prior block starting address or by adding the guide table value to the starting address. The memory access may be a memory read from the block of addresses or a memory write to the block of addresses. In the preferred embodiment, memory, a data processor and a data transfer controller performing the above memory accesses is constructed in a single semiconductor chip. The data transfer controller may access external memory in the same manner as on-chip memory.
