How To Integrate An Embedded FPGA


Choosing to add programmable logic into an SoC with an eFPGA is just the beginning. Other choices follow involving how many lookup tables (LUTs), how much routing and what topology, how will data be transferred in and out of the fabric, does data need to be coherent with system memory, how will it be programmed and tested, and what RTL functions need to be embedded into the programmable fabric ... » read more

Pushing Performance: Analysis and Optimization of Multicore Communication with SLX


In theory, multicore programming should be simple: Tasks are placed on available cores and allocated a data buffer in the shared memory to communicate data between two tasks. However, the amount of communication resources in the latest multicore SoC is very limited. One cannot deal with all the data communications required by all the tasks without being able to understand communication conte... » read more

Challenges In Using HLS For FPGA Design


High-level synthesis (HLS) tools, which transform C/C++ source code to Verilog/VHDL, have been commercially available for over 15 years. HLS tools from FPGA vendors and EDA companies promise improved productivity through a higher-level of abstraction, faster verification and quicker design iterations. For example, simulating your design in C/C++ can be 10 to 100x faster than simulating in RTL (... » read more

Finding And Avoiding Concurrency Bugs


Understanding the intended and unintended interactions between hardware and software components is changing as architectures become more heterogeneous and interconnect topologies get more complicated. This affects performance, power consumption and cost of the project. Lots of universities are researching this from a software perspective, while a small number are looking at the implications fro... » read more

The Case For Embedded FPGAs Strengthens And Widens


The embedded FPGA, an IP core integrated into an ASIC or SoC, is winning converts. System architects are starting to see the benefits of eFPGAs, which offer the flexibility of programmable logic without the cost of FPGAs. Programmable logic is especially appealing for accelerating machine learning applications that need frequent updates. An eFPGA can provide some architects the cover they ne... » read more

SLX Multi-Objective Optimization (MOPT)


Technologies such as autonomous cars and 5G communication are seeing a rapid increase in the number of processing elements (PE) per platform. Where software professionals were used to programming one, two or a handful of cores, the game has now changed. Intel’s Many Integrated Core Architecture [3] contains up to 78 cores, Nvidia Tegra XI[2] has up to 260 cores and Adapteva’s Epiphany-V[1] ... » read more

The Long And Detailed Road To Automotive Compliance


Compliance with automotive safety requirements is slowing down both innovation and participation by a flurry of startups as the whole ecosystem struggles to bring autonomous vehicles to reality. This is particularly onerous for chipmakers, which face a high bar for IC integrity and reliability. They must meet specifications and be free of design errors. Improper behavior in corner-case s... » read more

Big Shift In Multi-Core Design


Hardware and software engineers have a long history of working independently of each other, but that insular behavior is changing in emerging areas such as AI, machine learning and automotive as the emphasis shifts to the system level. As these new markets consume more semiconductor content, they are having a big impact on the overall design process. The starting point in many of these desig... » read more

Heterogeneous Design Creating Havoc With Firmware Versions


Adding different kinds of processing elements into chips is creating system-level incompatibilities because of sometimes necessary, but usually uncoordinated, firmware updates from multiple vendors. In the past, firmware typically was synchronized with other firmware and the chip was verified and debugged. But this becomes much more difficult when multiple heterogeneous processing elements a... » read more

Getting A Complete Picture Of Automotive Software


The automotive industry is currently undergoing a major disruption, usually referred as the shift to automated, connected, electric, and shared vehicles (ACES[1]). Naturally, these changes also have a significant impact on the requirements of the hard- and software architectures of these new vehicles: Service-oriented software architectures used by multiple applications running on generali... » read more
