چکیده

As the capacities of eld-programmable gate arrays (FPGAs) grow, it becomes desirable to create FPGAs with embedded memory arrays. This paper examines the exibility of the interconnect structure that joins memory and logic. For architectures with only a few memory arrays, we nd that both the routability and the delay of circuits are insensitive to the memory/logic interconnect exibility, which implies that this interconnection can be made very in exible. This is in contrast to the logic connection block exibility, which has been shown to require high exibility [1]. For architectures with more arrays, the memory/logic interconnect exibility requirements increase and approach those of logic interconnect.

The memory/logic interface in FPGAs with large embedded memory arrays

|As the capacities of eld-programmable gate arrays (FPGAs) grow, they will be used to implement much larger circuits than ever before. These larger circuits often require signiicant amounts of storage. In order to address these storage requirements, FPGAs with large embedded memory arrays are now being developed by several vendors. One of the crucial components of an FPGA with on-chip memory is...

Implementing logic in FPGA memory arrays: heterogeneous memory architectures

It has become clear that large embedded configurable memory arrays will be essential in future FPGAs. Embedded arrays provide high-density high-speed implementations of the storage parts of circuits. Unfortunately, they require the FPGA vendor to partition the device into memory and logic resources at manufacture-time. This leads to a waste of chip area for customers that do not use all of the ...

Hybrid FPGA : architecture and interface

Hybrid FPGAs (Field Programmable Gate Arrays) are composed of general-purpose logic resources with different granularities, together with domain-specific coarse-grained units. This thesis proposes a novel hybrid FPGA architecture with embedded coarse-grained Floating Point Units (FPUs) to improve the floating point capability of FPGAs. Based on the proposed hybrid FPGA architecture, we examine ...

Embedded Processor Based Built-In Self-Test and Diagnosis of Logic and Memory Resources in FPGAs

We present an embedded processor based approach for Built-In Self-Test (BIST) and diagnosis of programmable logic and memory resources in Field Programmable Gate Arrays (FPGAs). The resources under test include the programmable logic blocks (PLBs), large random access memories (RAMs), and digital signal processors (DSPs) in all of their modes of operation. The approach is applicable to any FPGA...

Autonomous Built-in Self-Test Methods for SRAM Based FPGAs

Built-in Self-Test (BIST) approaches for Static Random Access Memory (SRAM) based Field Programmable Gate Arrays (FPGAs) must be capable of fully testing the resources in the device. A summary of current techniques is presented in this paper that covers the three main components of modern FPGAs: logic blocks, interconnects and embedded FPGA cores. Overhead requirements, coverage capability, tra...
