• Design of an image-processing device for cost-sensitive, high-volume applications using a novel dynamically reconfigurable technology (Apr. 05, 2010)
  Many devices could benefit from programmability, but high-volume, cost-sensitive applications often force device manufacturers to use hard-wired RTL design techniques for reasons of end device cost. This results in the need for multiple silicon implementations to support different device variants, and means that device manufacturers are slow to respond to changing market requirements owing to the time taken to redesign, verify, manufacture and test a new device variant. Though programmability is highly desirable, the complete flexibility of function provided by a CPU or DSP-based solution is rarely necessary. This paper illustrates a design approach that uses a novel dynamically reconfigurable logic (DRL) technology to produce a device that is just reconfigurable enough to meet the flexibility requirements of the manufacturer whilst not imposing a significant size or power overhead compared to traditional RTL-based design techniques.
  
  
• A Flexible, Field-programmable ROM Replacement (Mar. 15, 2010)
  For large amounts of on-chip code and data, mask read-only memory (ROM) provides an inexpensive and easily programmed storage mechanism. However, the inability to configure ROM after wafer processing means that information stored in the ROM cannot be changed in the field. Antifuse one-time programmable (OTP) provides a flexible, field-programmable alternative to ROM. An antifuse-based bit cell uses controlled, irreversible thin (gate) oxide breakdown to program a bit.

• Embedded Symmetric MultiProcessing system on a SoC with 1.6GHz PowerPC IP in 45nm (Mar. 01, 2010)
  Because the dimensions of lithography are now closer to the fundamental physical limits, scaling is more and more difficult and thus multi-core processor solutions are just starting to be more popular in the embedded area. This paper describes in details the features that allow SoCs to be built with up to eight 1.6 GHz PowerPC CPU cores in an embedded system supporting Symmetric Multiprocessing (SMP) architecture. The balancing between CPU execution speed, memory bandwidth and latency, and coherency overhead has been the objective of the design of the PLB6 and the L2 Cache IP's, to reduce as much as possible the drop-off in performance-per-core inherent in an SMP approach.
