Unlike general-purpose computing systems, multicore embedded systems are designed with a specific application in mind. The memory access patterns for the application can be used to customize the memory architecture of the device. This chapter presents a synopsis of memory types and architecture commonly used in multicore embedded systems. It examines the many trade-offs that can be considered when designing the memory architecture. It considers factors such as whether the memory should be shared or distributed among the multiple cores; will the cores benefit from memory cache and what should the cache configuration be; is there a cache coherency protocol used; should there be other memory types on the device such as scratch pad SRAMs and eDRAMs; does the device use a DMA for memory transfers, and other factors. It provides guidance to the embedded system designers to tailor the memory architecture to their needs.

This chapter discusses the potential of and role of system virtualization in meeting the flexibility, scalability, portability, and robustness demands of next-generation multicore embedded systems. Common architectural approaches to hypervisors are compared, including a strong focus on effective sharing and management of I/O peripherals across virtual machines. The chapter also describes and contrasts the virtualization hardware assistance features available in common multicore processors. Finally, emerging applications and use cases enabled by system virtualization are provided.

Synchronization hardware is a fundamental requirement for concurrent software. Ultimately, software depends upon strong guarantees for atomicity, which can only be provided by hardware. Fortunately, hardware can provide a simple but powerful programming interface to higher-level software using only a few synchronization primitives. These few primitives can support a surprisingly broad range of capabilities in software. Yet, even with hardware support to ensure functional correctness, there is an unavoidable performance overhead to pay for synchronization. In recent years, hardware designed to replace precise locking with speculative lock avoidance (e.g., lock-free programming) has begun to emerge. This chapter provides an in-depth look at the lowest level hardware/software interface for synchronization, along with explanations of how the underlying hardware ensures atomicity, and considerations related to weakly consistent memory models. This is complemented with a discussion of various lock avoidance techniques.

As in any complex architecture, debug and instrumentation resources are critical for multicore design. Debug instrumentation provides information for post-silicon debug analysis, software optimization, and performance monitoring. In this chapter, we introduce debug concepts useful for multicore; we deconstruct and discuss different debug instrumentation blocks and interfaces, including typical operations and system integration; and we discuss differences, considerations, and approaches more appropriate to multicore debug. This is followed by multicore debug examples, some of which are based on open standards and some on commercially-available blocks from processor IP providers.
