Abstract: A portable heads-up display device for deployment on the dashboard of a vehicle. The device includes a housing suitable for mounting to or placing on a surface, and containing system electronics and a projector. A curved high-gain reflective screen disposed on the housing rearward of the projector receives an image produced by the projector, and reflects that image to a semi-transparent curved combiner disposed near the front of the housing. A virtual image appears at the combiner that has a focal point in the distance beyond the combiner. One or more rear-facing sensors and the control electronics detect hand gestures by the driver, which controls the operation of the device in displaying images. The device mounts to a dashboard via a conformable and foot that adapts to the shape of the dashboard. Magnetic coupling between the housing and a puck element held in the foot facilitates removal and replacement of the device.

Abstract: A method for processing data using a multiplexing architecture includes performing a selected one of a plurality of first multiplexer operations on the data and then a selected one of a plurality of second multiplexer operations. The first multiplexer operations include a pass operation and a plurality of bit rearrangement operations. The second multiplexer operations include a pass operation and a plurality of bit duplication operations which duplicates a selected bit or bits to a corresponding block of contiguous bits in the output. A result is then generated that reflects the outputs produced by first and second multiplexers respectively.

Abstract: A data processing system (e.g., microprocessor 30) for packing register data while storing it to memory and unpacking data read from memory while loading it into registers using single processor instructions. The system comprises a memory (42) and a central processing unit core (44) with at least one register file (76). The core is responsive to a load instruction (e.g., LDW_BH[U] instruction 184) to retrieve at least one data word from memory and parse the data word over selected parts of at least two data registers in the register file. The core is responsive to a store instruction (e.g., STBH_W instruction 198) to concatenate data from selected parts of at least two data registers into at least one data word and save the data word to memory. The number of data registers is greater than the number of data words parsed into or concatenated from the data registers. Both memory storage space and central processor unit resources are utilized efficiently when working with packed data.
