This example describes a 64-bit x 8-bit dual clock synchronous RAM design with separate read and write addresses in VHDL. Synthesis tools are able to detect RAM designs in HDL code and automatically infer the altsyncram or altdpram megafunctions depending on the target device architecture.
This example describes a 64-bit x 8-bit single-port RAM design with common read and write addresses in Verilog HDL. Synthesis tools are able to detect single-port RAM designs in the HDL code and automatically infer either the altsyncram or the altdpram megafunctions, depending on the architecture of the target device.
18 Μαρ 2024 · We can understand 32 and 64-bit architectures as the amount of data that a CPU processes each time. The architecture defines, for instance, the total memory supported by a register at once. Also, it typically determines the size of the instruction set employed by a processor.
This handout only mentions a small subset of the rich possibilities provided by the x86-64 instruction set and architecture. For a more complete (but still readable) introduction, consult The AMD64 Architecture Programmer’s Manual, Volume 1: Application Programming.
Looking Behind the Curtain of Software. The OS sits between hardware and user-level software, providing: Isolation (e.g., to give each process a separate memory region) Fairness (e.g., via CPU scheduling) Higher-level abstractions for low-level resources like IO devices.
Regardless of the technology, all RAM memory cells must provide these four functions: Select, DataIn, DataOut, and R/W. This “static” RAM cell is unrealistic in practice, but it is functionally correct.
15 Δεκ 2023 · At its heart, the X86-64 is notable for its 64-bit registers, which allow for a significant expansion in the handling of data — processors that utilize this architecture can theoretically access up to 16 exabytes of memory, though practical system limits are much lower.
