Problems solved by technology

Therefore, conventional systems require that all program codes be copied from flash memory to RAM at the beginning of system operation, and this has required the use of large amounts of expensive RAM
Unfortunately, the use of traditional dynamic sharing of RAM in software-defined communication systems is unacceptably expensive due to the relatively high cost of RAM compared to flash memory

Embodiment Construction

[0036] Example embodiments provide methods and structures for dynamic sharing of RAM between different state machine states of a software-defined TDD communication system. As used herein, the term "shared" RAM means that some, but not all, physical RAM addresses are reserved for use by certain classes of program code and constant-value code previously determined, respectively, according to (a) (b) according to the amount of physical RAM available at a particular time. The various classes are used respectively during corresponding concrete states of the state machine to store program code and / or constant code variables for execution of the corresponding concrete states. Program code includes instructions to be executed, and constant code variable data often includes things like look-up tables and filter coefficients.

[0037] Example embodiments focus on the dynamic sharing of program code and are based on the nature of state machines, in particular on the fact that each state...

Abstract

In described examples, dynamic sharing of RAM (75) in a software-defined communication system includes storing program code in a flash memory (71), categorizing parts of the code into groups of transmit categories according to when a part of the code needs to be copied into a section of a RAM (75) and then executed during a first state of a TX state machine and according to how another part of the code can be later fit into the same section and then executed during a second state. Similarly, parts of the code are categorized into groups of receive categories according to when a part of the code needs to be copied into a section of RAM (75) and then executed during a first state of a RX state machine and according to how another part of the code can be later fit into that section and then executed during a second state of the RX state machine, to reduce the amount of RAM (75) without sacrificing speed performance.

Description

technical field Background technique [0001] This generally relates to software-defined or software-programmable TDD (time division duplex) communication systems, and more specifically to a technique and structure for copying from flash memory to RAM ( Random Access Memory) and also dynamically shares RAM by classifying program code and / or data code copied from Flash memory according to how the available RAM space will be shared with other classes of code copied from Flash memory. The term TDD (Time Division Duplex) refers to where the forward (i.e. transmit) communication link is separated in time from the reverse (i.e. receive) A communication system in which communication links are separated. A software-defined communication system is a communication system in which components and functions are implemented by software in a programmable device such as a DSP (Digital Signal Processor) or FPGA (Field Programmable Gate Array). The software-defined communication system may be...
